2 Summer Flounder, Scup, and Black Sea Bass Monitoring Committee Webinar Meeting Summary - Scup July 25, 2016 Monitoring Committee Attendees: Mike Bednarski (MA DMF), Jason McNamee (RI DFW), Peter Clarke (NJ F&W), Greg Wojcik (CT DEEP), Katie May Laumann (VMRC), Steve Doctor (MD DNR), Rich Wong (DE DFW), John Maniscalco (NY DEC), T.D. VanMiddlesworth (NC DMF), Kiley Dancy (Council staff), Julia Beaty (Council staff), Kirby Rootes-Murdy (ASMFC staff), Wilson Laney (USFW) Additional Attendees: Liz Scheimer (NMFS GARFO), Nichola Meserve (MA DMF), Douglas Christel (MA DMF), Greg DiDomenico (Garden State Seafood Association), Katie Almeida (Town Dock), Mike Ruccio (NMFS GARFO) General Comments The Monitoring Committee does not currently have any formal control rules for the recommendation of Annual Catch Targets (ACTs). The Committee recognizes the need to develop ACT control rules or guidelines for addressing management uncertainty in the future, which would be applicable to all three species. The Monitoring Committee will continue to pursue additional analyses requested by the Council and Board in December 2015 related to the review of commercial measures conducted last fall (i.e., review of the feasibility of a common minimum mesh size, summarization of past gear studies, and scup-specific measures as discussed below). Scup Comments and Recommendations For the past five years the recreational and commercial scup fisheries have under-harvested their landings limits by 20-51%. The ABCs began to decline in 2012 and continue to do so through If recent fishery performance continues, landings may begin reaching quota limits by The Monitoring Committee noted that given increasing landings over the past several years, as well as high estimates of recruitment indicating a large 2015 year class, an assessment update in 2017 could be beneficial by way of producing more up to date information on current stock status and population size for scup. This could potentially mitigate issues created by the decreasing ABC and possibly increasing population size. The commercial landings monitoring and fishery closure system is timely and successful in managing the landings. States should continue to be diligent in managing their state quotas to ensure that large overages do not occur. The Committee agreed with the staff recommendation that no changes be made to the implemented management measures, including the 2017 and 2018 ACTs (Table 1), commercial minimum fish size (9- inch total length), gear requirements, and possession limits. The Monitoring Committee will evaluate the timing of the seasonal commercial quota periods, as requested by the Council and Board in December The Monitoring Committee discussed ideas for analyzing the biological and economic impacts of modifying the quota period dates. Any changes to the quota period dates would require a framework or amendment. 1

Moore, Ph.D., Executive Director M E M O R A N D U M DATE: July 7, 2016 TO: Chris Moore, Executive Director FROM: Julia Beaty and Kiley Dancy, Staff SUBJECT: Review of Scup Management Measures Executive Summary The Mid-Atlantic Fishery Management Council (Council) set multi-year specifications for scup in 2015, establishing catch and landings limits for the fishing years. The Council and the Atlantic States Marine Fisheries Commission s Summer Flounder, Scup, and Black Sea Bass Management Board (Board) will review the 2017 scup management measures during their joint meeting in August These measures may remain unchanged if the Scientific and Statistical Committee (SSC) determines that the previously recommended Acceptable Biological Catch (ABC) for 2017 (28.40 million pounds; 12,881 metric tons) is still appropriate and if the Council and Board recommend no changes to the previously implemented catch and landings limits. The Summer Flounder, Scup, and Black Sea Bass Monitoring Committee will also review recent fishery performance and make a recommendation to the Council and Board regarding any necessary modifications to the previously implemented 2017 Annual Catch Targets (ACTs) and commercial management measures (e.g., possession limits, quota period provisions, gear restrictions, and minimum fish size). The most recent benchmark stock assessment for scup was peer-reviewed and accepted by the Stock Assessment Review Committee (SARC) in June The assessment indicated that the scup stock was not overfished and overfishing was not occurring in The assessment model estimated a spawning stock biomass (SSB) of million pounds (182,915 mt) in This is more than double the biomass at maximum sustainable yield (SSBMSY proxy = SSB40% = million pounds = 87,302 mt). The fishing mortality rate on fully selected age 3 scup was in This is 42% lower than the fishing mortality threshold reference point of (FMSY proxy=f40%; NEFSC 2015). The Northeast Fisheries Science Center (NEFSC) provided a data update on scup fishery catch, landings, and discards, as well as NEFSC and state survey catches through This information indicates that scup biomass continues to be high, relative exploitation ratios remain low, and the 2015 year class appears to be large. Reported 2015 landings in the commercial fishery were million pounds (7,725 mt), about 80% of the 2015 commercial quota (21.24 million pounds, 9,632 mt). Estimated 2015 landings in the recreational fishery were 5.06 million pounds (2,295 mt), about 70% of the recreational harvest limit (7.25 million pounds, 3,288 mt). Total commercial and recreational landings in 2015 were million pounds (10,020 mt). Total commercial and recreational discards were 4.41 million pounds (2,000 mt). Total catch in 2015 was about million pounds (12,020 mt), about 79% of the 2015 ABC (NEFSC 2016). Page 1

5 Staff recommend maintaining the previously adopted 2017 ABC of million pounds as the basis for scup management measures in This ABC results in a commercial Annual Catch Limit (ACL) of million pounds (10,047 mt) and a recreational ACL of 6.25 million pounds (2,834 mt). In 2015 the Monitoring Committee recommended no reduction from the commercial and recreational ACLs to account for management uncertainty; therefore, both the commercial and recreational ACTs were set equal to their respective ACLs for The previously implemented 2017 scup commercial quota is million pounds (8,337 mt) and the recreational harvest limit is 5.50 million pounds (2,495 mt; Table 1). In 2015 the Monitoring Committee carried out a thorough review of the commercial management measures for the summer flounder, scup, and black sea bass fisheries which may be modified through the annual specifications process (MAFMC 2015B). The Council reviewed the Monitoring Committee s recommendations and Advisory Panel input in December 2015 and voted to increase the scup incidental possession limit for federally-permitted trawl vessels during November April from 500 to 1,000 pounds. No new analysis of commercial scup management measures has been completed since late 2015; therefore, staff recommend no changes to the commercial management measures for the scup fishery at this time.

7 Introduction The Magnuson-Stevens Act (MSA) requires that the Council s SSC provide ongoing scientific advice for fishery management decisions, including recommendations for ABC, prevention of overfishing, and achieving maximum sustainable yield (MSY). The SSC must recommended ABCs that addresses scientific uncertainty. The MSA mandates that the Council's catch limit recommendations for the upcoming fishing year(s) cannot exceed the ABC recommended by the SSC. The Council s Monitoring Committees are responsible for developing recommendations for management measures designed to achieve the ABCs recommended by the SSC. Specifically, the Monitoring Committee must recommend ACTs that are equal to or less than the ACLs to address management uncertainty, and must also recommend management measures designed to achieve these ACTs. Summer flounder, scup, and black sea bass are cooperatively managed by the Council and the Atlantic States Marine Fisheries Commission (the Commission) under a joint Fishery Management Plan (FMP). The Commission s Summer Flounder, Scup, and Black Sea Bass Management Board and the Council meet jointly to consider the recommendations of the SSC and Monitoring Committee before deciding on proposed scup catch limits and other scup management measures. The Council and Board may set multiyear specifications for scup for up to three years at a time. The Council and Board submit their scup management recommendations to the National Marine Fisheries Service (NMFS), which is responsible for implementation and enforcement of federal fisheries regulations. This memorandum includes information to assist the SSC and Monitoring Committee in reviewing their recommendations for 2017 management measures for the scup fishery, which were developed in Additional information about fishery performance and past management measures can be found in the 2016 Scup Fishery Information Document prepared by Council staff (MAFMC 2016A) and the 2015 Summer Flounder, Scup, and Black Sea Bass Fishery Performance Report developed by the Council and Commission Advisory Panels (MAFMC 2016B). Recent Catch and Landings Reported 2015 landings in the commercial scup fishery were million pounds (7,725 mt), about 80% of the 2015 commercial quota (21.24 million pounds, 9,632 mt). Estimated 2015 landings in the recreational fishery were million pounds (2,295 mt), about 70% of the recreational harvest limit (7.249 million pounds, 3,288 mt). Total commercial and recreational landings in 2015 were million pounds (10,020 mt). Total commercial and recreational discards were million pounds (2,000 mt). Total catch in 2015 was about million pounds (12,020 mt), about 79% of the 2015 ABC (NEFSC 2016). The scup commercial quota is allocated among three quota periods: Winter I (January 1 April 30), Summer (May 1 October 31), and Winter II (November 1 December 31). About 64% of the 2016 Winter I commercial scup quota was landed. As of the week ending June 25, 2016, 30% of the Summer commercial scup quota had been landed (Table 2). Page 4

The SSC used the Council s risk policy to derive their ABC recommendations from OFL projections provided with the 2015 benchmark stock assessment. The SSC used OFL projections which assumed that 75% of the 2015 ABC would be caught and that F in 2016 and 2017 would be 0.22 (FMSY). The SSC assigned a 60% coefficient of variation (CV) to the OFL, which is double the CV recommended by the SARC, but below the CV of 100% typically used by the SSC for species of this assessment level. The SSC used a probability of overfishing (p*) of 40% to derive the ABCs, based on the Council s risk policy for a species with a typical life history. Page 5

The ABC catch level shown for 2015 is 75% of the 2015 ABC.

As a result, the dynamics of the older ages of scup are driven principally by catches and inferences regarding year class strength. Uncertainty exists with respect to the estimate of natural mortality used in the assessment. Uncertainty exists as to whether the MSY proxies (SSB40%, F40%) selected and their precisions are appropriate for this stock. The SSC assumed that OFL has a lognormal distribution with a 60% CV, based on a metaanalysis of survey and statistical catch at age model accuracies. Survey indices are particularly sensitive to scup availability, which results in high inter-annual variability. Efforts were made to address this question in the Stock Assessment Workshop and Stock Assessment Review Committee (SAW/SARC) that should be continued; and The projection on which the ABC was determined is based on an assumption that the quotas would be landed in 2016, 2017, and Stock Status and Biological Reference Points Biological reference points estimated by the 2015 benchmark scup stock assessment include (NEFSC 2015): A biomass reference point of SSB MSY proxy = SSB40% = million pounds (87,302 mt) A minimum biomass threshold of ½ SSB MSY proxy = ½ SSB40% = million pounds (43,651 mt) A fishing mortality reference point of FMSY proxy = F40% = According to the 2015 benchmark scup stock assessment, the scup stock was not overfished and overfishing was not occurring in The assessment model estimated an SSB of million pounds (182,915 mt) in This is more than double the biomass at MSY (SSBMSY proxy = SSB40% = million pounds = 87,302 mt). The fishing mortality rate on fully selected age 3 scup was in This is 42% lower than the fishing mortality threshold reference point of (FMSY proxy=f40%). Page 6

10 The average recruitment from 1984 to 2014 was 109 million age 0 scup. The 2014 year class was estimated to be about 112 million fish (NEFSC 2015). Catch and survey data through 2015 indicate that scup SSB remains high, relative exploitation ratios remain low, and the 2015 year class appears to be large (NEFSC 2016). Other Management Measures Recreational and Commercial Annual Catch Limits The ABC is divided into a commercial ACL and a recreational ACL (Figure 1). As specified in the Summer Flounder, Scup, and Black Sea Bass FMP, the commercial scup ACL is 78% of the ABC and the recreational ACL is 22% of the ABC. The ACLs include both landings and discards. Staff recommend no changes to the previously implemented 2017 commercial ACL of million pounds (10,047 mt) and recreational ACL of 6.25 million pounds (2,834 mt). Annual Catch Targets The Monitoring Committee is responsible for recommending ACTs for the Council and Board s consideration. The ACTs may either be equal to the ACLs or reduced from the ACLs to account for management uncertainty. The Monitoring Committee should consider all relevant sources of management uncertainty in the scup fishery and provide the technical basis for any reduction in catch when recommending ACTs. Management uncertainty includes uncertainty in the ability of managers to control catch and uncertainty in quantifying the true catch (i.e., estimation errors). This can occur due to a lack of sufficient information about the catch (e.g., due to late reporting, under-reporting, and/or misreporting of landings or bycatch) or due to a lack of management precision (i.e., the ability to constrain catch to desired levels). In 2015 the Monitoring Committee recommended no reduction from the commercial and recreational scup ACTs to the ACLs for As indicated by the 2015 benchmark assessment and the 2016 data update, scup SSB is much higher than the biomass reference point. Both the commercial and recreational fisheries have landed well below their landings limits since 2011 (Table 4). For these reasons, staff recommend that the 2017 ACTs remain equal to the ACLs.

12 Commercial Quotas and Recreational Harvest Limit Commercial quotas and recreational harvest limits for scup are determined by subtracting projected discards from the sector-specific ACTs. Projected discards from the stock assessment are apportioned between the recreational and commercial fisheries using the average percentage of dead discards attributable to each sector over the past three years. According to the 2015 benchmark stock assessment, commercial dead discards accounted for an average of 83.4% of all dead discards from 2012 through Recreational dead discards accounted for an average of 16.6% of all dead discards from 2012 through The previously implemented 2017 commercial quota is million pounds (8,337 mt) and the 2017 recreational harvest limit is 5.50 million pounds (2,495 mt). As prescribed by the FMP, the commercial scup quota is divided into three periods: Winter I (January 1 April 30; allocated 45.11% of the commercial quota), Summer (May 1 October 31; allocated 38.95% of the commercial quota), and Winter II (November 1 December 31; allocated 15.94% of the commercial quota). Based on the previously implemented 2017 scup commercial quota, the 2017 Winter I commercial quota will be 8.29 million pounds (3,761 mt), the Summer quota will be 7.16 million pounds (3,247 mt), and the Winter II quota will be 2.93 million pounds (1,329 mt), prior to any quota rollover from Winter I, if applicable. Staff recommend no changes to the previously implemented 2017 commercial quota, the Winter I, Summer, and Winter II quotas, or the 2017 recreational harvest limit. Commercial Winter I and Winter II Quota Period Possession Limits The Council and Board use commercial scup possession limits to help constrain landings to the seasonal quotas. The Winter I possession limit is 50,000 pounds. After 80% of the Winter I quota is landed, the possession limit drops to 1,000 pounds. The Winter II possession limit is 12,000 pounds. The Winter II possession limit is an initial possession limit. If the Winter I quota is not fully harvested, the Winter II possession limit increases by 1,500 pounds for every 500,000 pounds of scup not caught during the Winter I period. There are no federal possession limits during the Summer quota period; however, there are state possession limits. In 2015 the Monitoring Committee recommended no changes to the Winter I and Winter II quota period possession limits (MAFMC 2015B). The Council and Board agreed with this recommendation. According to an analysis presented by Council staff, the majority of commercial scup trips in recent years landed well below the Winter I and Winter II possession limits. Based on this analysis, the Monitoring Committee saw no reason to modify these measures. Advisors have not recommended a change to these measures in recent years; however, one advisor noted that the staff analysis of these measures (MAFMC 2015B, MAFMC 2016A) appears to under-represent the number of trips which landed close to the Winter I possession limit in 2014 and Staff recommend no change to the Winter I and Winter II quota period possession limits for Commercial Minimum Fish Size The minimum size for retention of scup in the commercial fishery is 9 inches total length (TL). The Council and Board have not modified this measure since scup was first managed by the Council through Page 9

13 the 1996 amendment that added scup to the Summer Flounder FMP. The Council and Board considered modifying this measure in 2005, 2012, and As part of the commercial management measures review carried out by the Monitoring Committee in 2015, the Monitoring Committee recommended no change to the minimum fish size for scup in the commercial fishery. The Monitoring Committee noted that because such a high proportion of scup discards are smaller than 9 inches, reducing or eliminating the minimum size (as requested by some advisors) could significantly shift selectivity of the fishery and increase harvest of immature fish, which could have negative effects on scup biomass. The Monitoring Committee also noted that reducing or eliminating the minimum size could increase mortality in the commercial pot/trap and hook and line fisheries, which respectively accounted for 3.6% and 4.6%, of commercial scup landings between 2010 and 2014 (NEFSC 2015). Eliminating the commercial minimum size and relying on trawl mesh specifications to limit mortality of smaller scup, as proposed by some advisors, could create enforcement challenges given that scup are targeted using other commercial gear types. The federal commercial and recreational minimum scup sizes are currently identical, which is generally considered beneficial from an equity and enforceability perspective (MAFMC 2015B). In December 2015 the Council and Board agreed with the Monitoring Committee s recommendation and chose not to modify the minimum commercial scup size. Staff recommend that this regulation remain unchanged in Commercial Trawl Mesh Size Trawl vessels which possess more than 500 pounds of scup from November 1 through April 30 and more than 200 pounds of scup from May 1 through October 31 must use a minimum mesh size of 5.0 inches. In 2015 the Council recommended that the winter (i.e., May October) possession limit for vessels using mesh smaller than 5.0 inches be increased from 500 to 1,000 pounds. NMFS published a proposed rule to implement this change on May 23, The Council agreed to modify this measure in recognition of the substantial increase in SSB and the expansion of age structure of the population since this measure was last modified in Staff recommend no additional changes to this measure for Commercial Pot and Trap Regulations NMFS Vessel Trip Report data show that less than 1% of the 2015 commercial scup catch was taken with pots and traps. Pots and traps used in the commercial scup fishery must have either a circular escape vent with a 3.1 inch minimum diameter or square or rectangular escape vents with each side being at least 2.25 inches in length. The Council and Commission hosted a workshop in 2005 to review several studies on vent size. Workshop participants did not recommend any changes in the vent sizes for the commercial scup fishery. The Monitoring Committee reviewed these measures in 2015 and recommend no changes. Staff recommend no changes to these measures for Recreational seasons, possession limits, and minimum size The Council and Board will review recreational measures for 2017 (i.e., the recreational scup season, possession limits, and minimum fish sizes) at their December 2016 meeting. Data from the first four waves (i.e., the two-month reporting increments for recreational data) of 2016 recreational landings are expected to be available in October The Monitoring Committee will meet in November to review these landings data and make recommendations for any necessary changes in recreational management measures. Staff have no recommendations for 2017 recreational management measures at this time. Page 10

36 Scup Fishery Information Document June 2016 This document provides a brief overview of the biology, stock condition, management system, and fishery performance for scup with an emphasis on 2015, the most recent complete fishing year. 1. Biology Scup (Stenotomus chrysops) are a schooling, demersal (i.e., bottom-dwelling) species. They are found in a variety of habitats in the Mid-Atlantic. Essential fish habitat (EFH) for scup includes demersal waters, areas with sandy or muddy bottoms, mussel beds, and sea grass beds from the Gulf of Maine through Cape Hatteras, North Carolina. Scup undertake extensive seasonal migrations between coastal and offshore waters. Scup are found in estuaries and coastal waters during the spring and summer. In the fall and winter they move offshore and to the south, to outer continental shelf waters south of New Jersey. Scup spawn once annually over weedy or sandy areas, mostly off of southern New England. Spawning takes place from May through August and usually peaks in June and July. 1 About 50% of scup are sexually mature at two years of age and about 17 cm (about 7 inches) total length. Nearly all scup older than three years of age are sexually mature. Scup reach a maximum age of at least 14 years. They may live as long as 20 years; however few scup older than age 7 are caught in the Mid-Atlantic. 2, 3 Adult scup are benthic feeders. They consume a variety of prey, including small crustaceans (including zooplankton), polychaetes, mollusks, small squid, vegetable detritus, insect larvae, hydroids, sand dollars, and small fish. The Northeast Fisheries Science Center s (NEFSC s) food habits database lists several predators of scup, including several shark species, skates, silver hake, bluefish, summer flounder, black sea bass, weakfish, lizardfish, king mackerel, and monkfish Status of the Stock The scup stock was designated as overfished in 2005, triggering the establishment of a rebuilding plan (implemented in 2007 via Amendment 14 to the Fishery Management Plan). Scup were declared rebuilt ahead of schedule in 2009 after a benchmark stock assessment determined that the stock was no longer overfished and overfishing was not occurring. 2 The most recent benchmark stock assessment for scup took place in 2015 and determined that scup were not overfished and overfishing was not occurring in 2014 (Figures 1 and 2). 3 1

38 3. Management System and Overall Fishery Performance The Mid-Atlantic Fishery Management Council (Council) and the Atlantic States Marine Fisheries Commission (Commission) work cooperatively to develop fishery regulations for scup off the east coast of the United States. The Council and Commission work in conjunction with the National Marine Fisheries Service (NMFS), which serves as the federal implementation and enforcement entity. This cooperative management endeavor was developed because a significant portion of the catch is taken from both state waters (0-3 miles offshore) and federal waters (3-200 miles offshore, also known as the Exclusive Economic Zone or EEZ). The management unit for scup includes U.S. waters from Cape Hatteras, North Carolina to the U.S.-Canadian border. The Fishery Management Plan (FMP) for scup has been in place since 1996, when scup were incorporated into the Summer Flounder FMP through Amendment 8 to that plan. Amendment 8 also established measures to ensure effective management of scup fisheries, including gear restrictions, reporting requirements, commercial quotas, a moratorium on new commercial scup permits, recreational possession limits, and minimum size restrictions. The Council has made several adjustments to the FMP since The FMP and subsequent amendments and framework adjustments can be found at: Scup fisheries are currently managed through output controls (catch and landings limits), with 78% of the allowable catch allocated to the commercial fishery and 22% of allowable catch allocated to the recreational fishery. The Council s Scientific and Statistical Committee (SSC) recommends annual Acceptable Biological Catch (ABC) levels for scup, which are then approved by the Council and Commission and submitted to NMFS for final approval and implementation. The ABC is divided into commercial and recreational Annual Catch Limits (ACLs), based on the quota allocation percentages prescribed in the FMP (i.e., 78% commercial, 22% recreational). The Council first implemented recreational and commercial ACLs with a system of overage accountability in Both ABCs and ACLs are catch-based limits, meaning they include both projected landings and discards. Projected discards are subtracted to determine the commercial quota and recreational harvest limit, which are landings-based limits. Table 1 shows scup catch and landings limits from 2007 through 2018, as well as commercial and recreational landings through Scup support sizable commercial and recreational fisheries in the Mid-Atlantic region. Total scup landings (commercial and recreational) from Maine to North Carolina peaked in 1981 at over 27 million pounds and reached a low of 5.1 million pounds in In 2015, about 22.0 million pounds of scup were landed by commercial and recreational fishermen (Figure 3). 4,5 3

39 Table 1: Summary of catch limits, landings limits, and landings for commercial and recreational scup fisheries from 2007 through Measure e 2018 e ABC (mil. lb) a TAC (mil. lb) b Commercial ACL (mil lb) c Commercial quota (mil lb) d Commercial landings (mil. lb) % of commercial 104% 100% 98% 100% 74% 53% 76% 72% 80% quota landed Recreational ACL (mil lb) c Recreational harvest limit (mil. lb) d Recreational landings (mil. lb) % of recreational limit harvested 166% 207% 125% 198% 64% 49% 72% 66% 74% a The ABC is the annual Acceptable Biological Catch for the entire scup fishery, and is divided into sector-specific Annual Catch Limits (ACLs) for the commercial and recreational fisheries. The ABC and ACLs include both landings and discards. b Prior to the implementation of the 2011 Omnibus ACLs and AMs Amendment, the Council specified a Total Allowable Catch (TAC). After implementation of this amendment, the Council specified ABCs instead of TACs. Both terms refer to the total catch limit in a given year. The difference between the TAC and the ABC in 2009 is due to NMFS specifying a revised catch limit after new scientific information became available. In 2011, the difference was due to the Council specifying a more conservative limit than that recommended by the SSC. c ACLs are annual sector-specific catch limits for the commercial and recreational fisheries. ACLs include both landings and discards. d Commercial quotas and recreational harvest limits reflect the removal of projected discards from the sector-specific ACLs. For , these limits are also adjusted for Research Set Aside (RSA). Quotas and harvest limits for do not reflect an adjustment for RSA due to the suspension of the program in e In 2015, the Council implemented ABCs, ACLs, commercial quotas, and recreational harvest limits for The 2017 and 2018 measures will be reviewed by the SSC, the Council, and the Commission in 2016 and 2017, respectively, and may be modified. 4

Commercial Fishery Regulations and Performance Commercial landings for scup peaked in 1981 at million pounds and reached a low of 2.66 million pounds in 2000 (Figure 3). In 2015, commercial fishermen landed million pounds of scup, about 80% of the commercial quota. 4 A moratorium permit is required to fish commercially for scup. Moratorium permits became a requirement in the commercial scup fishery after Amendment 8 established a limited-entry system. In 2015, 650 vessels held moratorium permits for scup. 6 The commercial scup fishery operates year-round, taking place mostly in federal waters during the winter months and mostly in state waters during the summer. A coast-wide commercial quota is allocated between three quota periods, known as winter I, summer, and winter II (Table 2). The Council and Commission developed these seasonal quota periods ensure that both smaller day boats, which typically operate near shore in the summer months, and larger vessels, which typically operate offshore in the winter months, have the ability to land scup before the annual quota is reached. The summer period quota is divided among states according to the allocation percentages outlined in the Commission s FMP (Table 3). Once the quota for a given period is reached, the commercial fishery is closed for the remainder of that period. If the full winter I quota is not harvested, unused quota is added to the quota for the winter II period. Any quota overages during the winter I and II periods are subtracted from the quota allocated to those periods in the following 5

41 year. Quota overages during the summer period are subtracted from the following year s quota only in the states where the overages occurred. A possession limit of 50,000 pounds of scup is in effect during the winter I quota period. A possession limit of 12,000 pounds is in effect during the winter II period. If the winter I quota is not reached, the winter II possession limit increases by 1,500 pounds for every 500,000 pounds of quota not caught during winter I. The winter II possession limit was 18,000 pounds in 2015 due to quota rollover from the winter I period. Almost 96% of the 1,307 commercial trips which landed scup during the winter II period in 2015 landed less than 10,000 pounds of scup. 4 The Council increased the winter I commercial scup possession limit from 30,000 pounds to 50,000 pounds in Over the past five years, less than 1% of the commercial trips which landed scup during the winter I period landed more than 20,000 pounds (Table 4). Table 2: The dates, allocations, and possession limits associated with the three quota periods for the commercial scup fishery. Quota Period Winter I Summer Winter II Dates January 1 April 30 May 1 October 31 November 1 December 31 Percentage of commercial quota allocated 45.11% Possession limit 50,000 pounds, until 80% of winter I allocation is reached, then reduced to 1,000 pounds % State-specific 15.94% 12,000 pounds. If winter I quota is not reached, the winter II possession limit increases by 1,500 pounds for every 500,000 pounds of scup not landed during winter I.

In 2015, about 98% of the scup caught (by weight) by federal commercial fishing permit holders were caught with bottom otter trawls. All other gear types each accounted for less than 1% of the commercial scup catch in Trawl vessels with a scup moratorium permit may not possess 500 pounds or more of scup from November 1 through April 30, or 200 pounds or more from May 1 through October 31, unless fishing with nets that have a minimum mesh size of 5-inch diamond mesh, applied throughout the codend for at least 75 continuous meshes forward of the terminus of the net. These limits are known as the trawl incidental possession limits. In December 2015 the Council voted to increase the winter (i.e., November 1 through April 30) scup incidental possession limit from 500 to 1,000 pounds. This measure has not yet been implemented, but is expected to be in effect by November 1, Pots and traps for scup are required to have degradable hinges and escape vents that are either circular with a 3.1 inch minimum diameter or square with a minimum length of 2.25 inches on the side. Two scup Gear Restricted Areas (GRAs) were first implemented in 2000 with the goal of reducing scup discards in small-mesh fisheries (i.e., mesh smaller than that required in the commercial scup fishery). Trawl vessels may not fish for or possess longfin squid, black sea bass, or silver hake in the Northern GRA from November 1 December 31 and in the Southern GRA from January 1 March 15 unless they use mesh which is at least 5 inches in diameter (Figure 4). In April 2016 the Council voted to modify the boundaries of the Southern Scup GRA. This modification has not yet been implemented. The GRAs are thought to have contributed to the recovery of the scup population in the mid- to late-2000s. 8 7

Vessel Trip Report (VTR) data suggest that NMFS statistical areas 537, 613, and 616 were responsible for the largest percentage of the commercial scup catch in Statistical area 539, off of Rhode Island, had the highest number of trips which caught scup (Table 6, Figure 5). 7 Table 6: Statistical areas that each accounted for at least 5% of the total commercial scup catch in 2015, with associated number of trips. 7 Statistical Area Percent of 2015 Commercial Scup Catch Number of Trips % 1, % 1, % % 1, % 1,636 8

44 Figure 5: NMFS Statistical Areas, highlighting those that each accounted for more than 5% of the commercial scup catch in Over the past two decades, total scup ex-vessel revenue ranged from a low of $4.8 million in 2000 (adjusted to real 2015 dollars to account for inflation) to a high of $11.3 million in In 2015, million pounds of scup were landed by commercial fishermen from Maine to North Carolina. The average price per pound was $0.67, which resulted in a total ex-vessel value of $11.3 million. 4 There is a strong relationship between the amount of scup landed in a given year and the average price per pound. As landings increase, price generally decreases (Figure 6). The highest average price per pound over the past two decades was $1.46 ($2.23 in 2015 dollars) and occurred in The lowest mean price per pound was $0.55 ($0.51 in 2015 dollars) and occurred in
