Conservation and management measures (CMMS)
Conservation and management measures (CMMs) describe binding decisions agreed on by the members and cooperating non-members of the Western and Central Pacific Fisheries Commission (WCPFC) at its annual meeting. These two groups and a third, participating territories, are known collectively as CCMs. Among the members are the 14 small island developing states (SIDS) of the Western and Central Pacific Ocean.
CMMs relating to bycatch direct the SIDS’ and other members’ policies and rules for managing tuna fisheries. They include reducing harm to other animals such as sharks, sea turtles, whales, dolphins, and seabirds.
- Encourage the use of non-entangling design and materials when constructing FADs to reduce entanglement of marine species
- Promote the use of natural or biodegradable materials to avoid synthetic marine debris
- Mesh should be avoided, but if it is used, mesh must be less than 7 cm when stretched
- Any mesh used on raft to be securely wrapped so as not to hang, and if used in tail must be tightly bundled and tied into a sausage shape
- The Scientific Committee will continue to review research and recommend the best materials to use. The WCPFC will consider adopting new measures regarding materials used in FADs in 2020
- Vessels are prohibited from setting a purse seine on a school of tuna when a cetacean is sighted before commencement of the set
- Ensure the safe release of any cetacean accidentally encircled in a purse-seine net, and report the details of these incidents
- Keep the safety of the crew as a paramount concern over any efforts to release whales or dolphins
2018-04, Sea turtles
- This measure came into effect on 1 January 2020, and will replace CMM 2008-03
- Implement FAO’s Guidelines to reduce sea turtle mortality in fishing operations, and ensure the safe handling of all captured turtles
- Ensure fishers bring on board any captured hard-shell turtle that is comatose or inactive, and foster its recovery before returning it to the water
- Ensure operators of purse-seine vessels:
– avoid encircling sea turtles, but if turtles are accidentally entangled, ensure that they are safely released;
– release all sea turtles entangled in FADs or other fishing gear;
– stop a net roll if a turtle is entangled, and release it before continuing the net roll; and
– carry and use dip nets to handle turtles
- Ensure operators of longline fishing vessels carry and use line cutters, de-hookers and dip nets to handle and promptly release any turtles caught or entangled
- Ensure longline vessels set for shallow-set fishing use at least 1 of these measures to reduce their impact on turtles: large circle hooks that have an offset of no more than 10°, finfish bait only, or another approved measure
- The Scientific Committee may waive the previous requirement if the country can demonstrate both minimal interaction with sea turtles over 3 consecutive years and observer coverage of at least 10% during the same period
- Operators of fishing vessels must record and report all incidents involving turtles
- Report the results of any research into modified FADs that avoid turtle entanglement
- States the species of sharks the CMM applies to
- CCMs will implement the FAO International plan of action for the conservation and management of sharks, and report to the Commission how they are doing this
- Each CCM will submit data on the WCPFC Key Shark Species for Data Provision
- Finning is prohibited
- All parts of any sharks that are retained on board must be used
- Each shark carcass must be kept, with its fins, in the same bag, preferably biodegradable. Each bag is to be identified clearly so that inspectors can verify the information. Each shark carcass must be landed or transhipped with its fins.
- Lists requirements for specific sharks
- This CMM replaced CMMs 2010-07, 2011-04, 2012-04, 2013-08 and 2014-05 on 1 November 2020
- Notes international conservation conventions that list mobula and manta rays, and notes that they are vulnerable to overfishing
- CCMs will prohibit their vessels from targeting mobulid rays, and will report to the Commission how they meet this CMM
- They are prohibited from keeping on board, transhipping or landing any mobulid rays (whole or part animal)
- Fishing vessels are to release any mobulid rays they catch promptly, alive and unharmed
- Any ray that is unintentionally caught and landed must be surrendered to government authorities. These rays may not be sold or bartered, but may be given away for eating.
- Implement FAO’s International plan of action for reducing incidental catches of seabirds in longline fisheries (IPOA-Seabirds)
- Report on how IPOA-Seabirds is implemented, including national plans of action for reducing incidental catches of seabirds in longline fisheries
- Longline vessels fishing south of 30°S are to use at least 2 of the following 3 measures: weighted branch lines, night setting or tori lines (bird-scaring lines); or hook-shielding devices
- From 1 January 2020, require longline vessels fishing from 25°S–30°S are to use 1 of these measures: weighted branch lines, tori lines, or hook-shielding devices. This requirement does not apply in the EEZs of Cook Islands, Fiji, French Polynesia, New Caledonia, or Tonga.
- Countries fishing south of 25°S are encouraged to collect data on interactions with seabirds, increase observer coverage as appropriate, and implement seabird-mitigation measures when operating inside their EEZ
- Large longline vessels (>24 metres) fishing north of 23°N are to use at least 2 of the mitigation measures listed in the table below. At least 1 of those measures must be from Column A.
- Small longline vessels (<24 metres) fishing north of 23°N are to use at least 1 of the mitigation measures listed in Column A in the table below.
- All longline vessels fishing in areas between 25°S and 23°N are encouraged to use 1 or more of the seabird bycatch-mitigation measures listed in the table below
- All countries with longline vessels fishing from 25°S to 23°N are encouraged to report annually on the mitigation measures they require vessels to use, and report on any changes made to these requirements
- Undertake research and report on any research that improves seabird bycatch-mitigation measures
- Use measures that make sure that any seabird captured alive during longlining is released alive and in the best possible condition, including removing any hooks
- Report annually all data collected by observers on interactions with seabirds
