11 The CMLR Convention 3. ny harvesting shall be conducted in accordance with the following principles of conservation: (a) prevention of decrease in the size of any harvested population to levels below those which ensure its stable recruitment. (b) maintenance of the ecological relationships between harvested, dependent and related populations and the restoration of depleted populations and (c) prevention or minimisation of the risk of changes in the marine ecosystem which are not potentially reversible over two or three decades,

12 The CMLR Convention, and the institutional structure, provide for decision-making based on best available science...data supports the science

13 Fishery data requirements The requirements for collecting and submitting data to the Data Centre are generally described in the Schedule of Conservation Measures in Force (annual publication available from the CCMLR website). Standard forms capture data from: Fisheries in the Southern Ocean Scientific observations on board fishing vessels Fishery-based research Research surveys and ecosystem monitoring Compliance activities and processes.

14 Data requirements The types of data required by CCMLR include: Fishery data Catch and effort real-time reports Haul-by-haul data for catch and effort, biological data and VME-indicator taxa STTLNT catch and effort data (public domain) Scientific observer data Cruise report Logbook data (e.g. fishing operations, biological data, mitigation, tag-release data, fish condition and hooking injuries) Survey data Fishery survey data (surveys and research fishing)

15 Data requirements (continued ) Compliance data Vessel information (including movements) Licensing Inspectors and inspections Vessel Monitoring System (VMS) Catch Documentation Scheme (CDS) Transhipments Fishery Notifications (new, exploratory, krill)

21 Regulatory framework for fisheries fishery is not allowed to expand faster than the acquisition of information necessary for achieving CCMLR s management objectives. There are 5 types of fisheries: New fishery notification, no recent information Exploratory fishery notification, fishery-based research Established fishery Lapsed fishery Closed fishery comprehensive stock assessment, notification (krill) operation has ceased due to commercial considerations, assessment no longer current directed fishing on the target species is prohibited

22 Regulatory framework for fisheries New fishery biological data (including species distribution and abundance) and fishery data are not available, or data from the two most recent fishing seasons have not been submitted to CCMLR notification is required prior to fishing (Measure 21-01) becomes an exploratory fishery after the first year of fishing.

23 Regulatory framework for fisheries Exploratory fishery not allowed to expand faster than the acquisition of information necessary for managing the fishery within CCMLR s management objectives notification and permission are required prior to fishing (Measure 21-02) remains an exploratory fishery until sufficient information is available on appropriate catch and effort levels, and on the potential impacts on dependent and related species.

24 Regulatory framework for fisheries Established fishery appropriate time series of data to support a comprehensive stock assessment and evaluation of a management strategy notification and permission are required prior to fishing for krill (Measure 21-03), and are optional for other target species.

25 Regulatory framework for fisheries Lapsed fishery fishing operations have ceased due to commercial considerations and assessments are no longer current/valid. Closed fishery directed fishing on the target species is prohibited.

26 Setting catch limits CCMLR sets catch limits using a set of decision rules to determine what proportion of the stock can be fished while still achieving the objective of the Convention. To do this the population of the harvest species is projected forward in time using a population model to allow the effects of different catch levels to be simulated.

27 Setting catch limits Two population levels have been agreed as the basis of the decision rules. These levels are the fractions of the population that can be taken by the fishery each year so that the spawning biomass (i.e. the population of the target species old enough to spawn): 1) only drops below 20% of the pre-fishing median on 1 in 10 years during the projected period of fishing (shown by the red dot) 2) after projected period of fishing, is 75% (krill and icefish) or 50% (toothfish) of the median before fishing started (the right hand blue distribution)

28 Setting catch limits In the case of krill the size of the stock is estimated from acoustic surveys. For icefish, a species that shows very highly variable population size, a short-term projection is made using a biomass estimate provided by a survey of the population every one or two years. For other fish species (e.g. toothfish) a range of approaches, including surveys, tag-recaptures and catch statistics are used.

29 nnual fishing season CCMLR fisheries are managed on an annual cycle (Measure 32-01) Starts 1 December each year Ends 30 November of the following year. This period is referred to as the fishing season, and fisheries may operate throughout this period or during shorter, defined intervals within the period.
