Conservation Measures for All Vessels
To be compliant, all vessels must:
- Not appear on an IUU List
- Have an IMO number (when meeting
IMO minimum requirements) - Have a company policy prohibiting shark finning and requiring sharks be landed with fins naturally attached, if retained
- Not have been found conducting shark finning and/or landing sharks without their fins naturally attached, if retained, within the past 2 years
- Be on an RFMO authorized record, if required
- Be flagged to an RFMO member or Cooperating Non-Member (CNM)
- Not use large-scale pelagic driftnets
Conservation Measures for Purse Seine Vessels
Purse-seine vessels listed on the PVR also must:
- Have been actively fishing for tuna by December
31, 2012 or if a new construction, have replaced existing capacity - Have a Unique Vessel Identifier (UVI), if applicable
- Be able to prove 100% observer coverage of large-scale vessels (human or electronic)
- Retain all caught tunas
- Ensure that their skippers are trained in best practices and responsible fishing operations for tuna purse seine fisheries, as described above
- Be required to implement a Company public policy on purse seine FAD Management best practices, including the following elements:
(a) Comply with flag state and RFMO reporting requirements for fisheries statistics by set type
(b) Report additional FAD buoy data (FAD daily position data and echosounder acoustic records) for use by RFMO science bodies
(c) Support science-based limits on the overall number of FADs used per vessel and/or FAD sets made
(d) Use only non-entangling FADs without netting to reduce ghost fishing
(e) Mitigate other environmental impacts due to FAD loss including through the use of biodegradable FADs and FAD recovery policies
(f) For silky sharks (the main bycatch issue in FAD sets) implement further mitigation efforts
- Engage in no transshipment on the high seas
