STATE OF THE CALIFORNIA SOUTH COAST SUPPLEMENTAL REPORT COMMERCIAL FISHERIES Researchers from the California Department of Fish and Wildlife (CDFW) used landings data from CDFW s Commercial Fisheries Information System to characterize the status of commercial fishing in the South Coast which encompasses California s jurisdictional waters (-3 nautical miles from shore) from Point Conception in Santa Barbara County to the US MEX border, including state waters around offshore Islands, from 1992-215. The analysis includes an overview of all commercial fisheries with additional focus on specific species, referred to as fisheries of interest (FOIs) and gear types (Table 1).

Landings (pounds) and Ex-Vessel Revenue (21$) (millions) Number of Fishermen Commercial Landings and Ex-Vessel Revenue Total landings, ex-vessel revenue, and the number of active fishermen within the commercial fishing industry can fluctuate within a year, and through time, as a multitude of factors come into play. Commercial fisheries can be impacted: If the quantity or quality of harvestable species change in response to environmental conditions (e.g. El Niño), As consumer demand and willingness to pay within an economy fluctuates, If the cost of fuel increases or decreases, and If there are regulatory changes in a fishery (e.g. the amount of fish that can be caught). From 1992-215, the South Coast s reported total commercial landings for all commercial fisheries has fluctuated with a high in 2 of approximately 428 million pounds landed to a low in 215 of less than 7 million pounds 5 2,5 landed (Figure 1).

Relative Percent Contribution Landings (pounds) and Ex-Vessel Revenue (21$) (millions) Number of fishermen Commercial Landings and Ex-Vessel Revenue: Fisheries of Interest Reported landings and ex-vessel revenue for the South Coast FOIs, shown in Figure 2, followed a similar trend as all commercial fisheries in the region, shown in Figure 1. This is attributed to the significant proportion FOIs contribute to reported landings and ex-vessel revenue (Figure 3)., 215 From 1992-215, reported landings fluctuated from a high of 41 million pounds in 2 to a low of 6 million pounds in 215. Reported ex-vessel revenue averaged $57 million from 1992-215, with a maximum of $9 million in 21, and a minimum of $26 million in 1998. The number of active fishermen in the South Coast FOIs decreased from 1994-26, remained relatively stable from 26-213, and then decreased to an all-time low of 532 fishermen in 215 (Figure 2). 1 9 45 4 35 3 25 2 15 1 5 Landings Ex-Vessel Revenue Number of Fishermen 1,8 1,6 1,4 1,2 1, Figure 2.

Landings (millions of pounds) Landings (millions of pounds) High Volume Fisheries High volume fisheries contribute considerably to total landings and reported ex-vessel revenue. For example, Market Squid thrives in relatively cool waters (5-6 F), so the presence of three strong El Niño events (1991-1992, 1997-1998, and 215-216) and the resulting above average sea surface temperature contributed to sharp declines in reported Market Squid landings (Figure 4A). Reduced Market Squid landings correlate to three of the lowest years in the South Coast s reported ex-vessel revenue (Figure 1). In warm water years, fishery effort typically shifts from Market Squid towards Coastal Pelagic Species, driven by the abundant Pacific Sardine. However, Pacific Sardine has experienced declines in biomass by about 9% since 27, resulting in a federal fishery closure along the entire US west coast in 214 which has continued into 216. The combination of low Market Squid landings and a fishery closure for Pacific Sardines contributed to the reduced commercial fishing season for 215 (Figure 2). 45 4 35 A 3 Other 25 2 15 1 Urchin-Dive Coastal Pelagic Species- Seine Net Squid-Brail 5 Squid-Seine Net - 4.5 4. 3.5 3. 2.5 2. 1.5 1..5 - B Nearshore Finfish-live-Trap Nearshore Finfish-live-Hook and Line Nearshore Finfish-live- Nearshore Finfish-dead- Nearshore Finfish-dead- Hook and Line Halibut-Trawl Halibut-Hook and Line Prawn-Trap Sea Cucumber-Trawl Sea Cucumber-Dive Lobster-Trap Rock Crab-Trap Figure 4.

Ex-Vessel revenues (millions, 21$) Ex-Vessel revenues (millions, 21$) Market Squid harvested by purse seine nets was the most important FOI in the South Coast for both reported landings (Figure 4A) and ex-vessel revenue (Figure 5A). Coastal Pelagic Species and Urchins were the second and third most landed species in the South Coast respectively (Figure 4A). Urchins and Lobsters were the second and third most lucrative species for ex-vessel revenue in the South Coast respectively (Figure 5A). 12 1 A 8 6 4 2 Other Coastal Pelagic Species-Seine Net Lobster-Trap Urchin-Dive Squid-Seine Net 14 12 1 8 6 B Nearshore Finfish-live-Trap Nearshore Finfish-live- Nearshore Finfish-live-Hook and Line Nearshore Finfish-dead- Nearshore Finfish-dead-Hook and Line Halibut-Trawl Halibut-Hook and Line 4 Sea Cucumber-Trawl 2 Sea Cucumber-Dive Squid-Brail Rock Crab-Trap Prawn-Trap Figure 5.

These FOIs, while landed in low abundance relative to other FOIs in the South Coast, get markedly higher prices per pound landed than other FOIs in the region (Figure 6).

Invertebrate Fisheries Although Lobster does not contribute significantly in way of landings (Figures 4B), its average price per pound was the highest among all South Coast FOIs (Figure 6), and has increased for all ports combined since 25 (Figure 7). This increase in average price per pound contributed to Lobster s claim as the third most lucrative fishery in the South Coast (Figure 5A). 2 18 16 14 12 1 8 6 4 2 Figure 7.

Changes in the socioeconomic landscape (including changes in fish availability, fishery restrictions, and consumer demand) before, during, and after the implementation of MPAs in the South Coast, as well as the short time-scale since MPA implementation (3 years of data), impede the analysis of the effects of these MPAs on commercial fisheries in the region. Over time, analyses may be able to parse out any words Socioeconomics potential MPA effects on the South Coast. However, an independent survey conducted by Point97/Ecotrust looking at MPA impacts on fishermen identified that in 212, 1% of the 114 fishermen interviewed throughout that South Coast indicated that at least one of the fisheries they participated in was directly impacted by the implementation of MPAs.
