Number of Class-6 PS vessels by flag stratified by the percentages of OBJ sets in 2015-2016.

Ordenamiento para atunes tropicales-Management for tropical tunas

• Management measures to restrict YFT catches were in effect from 1966-1979.
• No management measures were in place from 1980-1997.
• All management measures prior to 1998 applied only to YFT.
• 2001 was the last measure that applied only to YFT.

Since 2002, conservation and management measures to control fishing mortality levels in purse-seine fishery have become increasingly restrictive: 31 closure days in 2002 72 closure days in 2017

All PS vessels classes 4-6 >182 t must stop fishing in the EPO for a period of 72 days, choosing to apply one of the two closure periods specified for each year;

• 29 July to 8 October, or
• 9 November to 19 January of the following year

2018-2020, Closure period for PS vessels- Periodo de veda para Cerqueros

Closure of the PS fishery for yellowfin, bigeye, and skipjack tuna Within area bounded by 96º and 110ºW and

Area Vedada- Closed area (2018-2020)

Each PS vessel is limited the following number of active FADs, by vessel class: Class 6 (1,200 m3 and greater): 450 FADs Class 6 (< 1,200 m3): 300 FADs Class 4-5 (213 - 425 m3): 120 FADs Class 1-3 (< 213 m3): 70 FADs

• FADs can only be activated onboard a PS vessel

(i.e. remote activation not allowed)

• FADs cannot be deployed within 15 days prior to

the start of a vessel’s observed closure

• When fishing within 15 days prior to the start of

a vessel’s observed closure, all Class-6 PS vessels must recover and retain on board a number of FADs equal to the number of FADs sets made

Medidas para FADs- Measures for FADs (2018-2020)

Diseño de FADs no enmallantes- Non- entangling FADs design

To reduce entanglements of sharks, sea turtles and other species, the design and deployment of FADs should be based on the following principles.

• If a flat raft is used as a FAD surface structure, it should not be covered,
• r covered only with material that attempts to minimize entanglements.
• Any subsurface component of the FAD should be constructed in a

manner designed to avoid entangling marine life.

• To reduce the amount of synthetic marine debris, the use of natural or

biodegradable materials (such as hessian canvas, hemp ropes, etc.) for drifting FADs should be promoted.

IATTC acknowledging Significant effect that FADs may have on BET spawning biomass. The increased exploitation of SKJ in sets made on FADs and unassociated schools. In 2018

• The scientific staff, the SAC and WG on FADs, shall present to the Commission initial recommendations
• Additional elements for data collection necessary to evaluate the effects of the use of FADs on the ecosystem
• Research results regarding the use of non-entangling and biodegradable material for FAD construction, along with specific

recommendations.

• Assessment of possible effects of FADs in the tuna fishery in the EPO.
• The management of FADs,

Medidas adicionales para FADs-Additional measures for FADs

Antecedentes del manejo de FADs en el OPO- EPO FADs management background

• 1998, limited PS catch of Bet to 45,000 mt and prohibited PS sets on

FOBs once that limit was reached

• 1999, limited PS catch of Bet to 40,000 mt and prohibited PS sets on

FOBs once that limit was reached

• 2000 and 2001, a ban on sets on FOB from September-15 to

December, with the possibility of earlier closure 2 weeks after reached a limit of 40,000 t this limit of BET (<60 cm)

• 2017, limited the combined catches of YFT and BET in the fishery on

FOBs to 97,711 t; and 162,182 t for the fishery on dolphins.

combined effort of Members, the fishing industry and IATTC staff

inter alia:

• Take measures to ensure the long-term

sustainability of the tuna and other resources associated with the FAD fishery.

• Establish measures to avoid, reduce and minimize

the bycatch of juvenille tuna and of non-target species in the FAD fishery.

• Develop means of effectively monitor the number
• f active buoys and reporting of the same in order

to be able to verify compliance with established FAD limits.

• Collect and provide data that will allow the impacts
• Additional data, analysis and management measures needed for FAD fishery

2018 stock assessments for BET and YFT and recomendations

2018 IATTC RECOMMENDATIONS:  Maintain the provisions of the current resolution C-17-02.  For PS fishery, limit the annual number of FOB and UNA sets combined by Class-6 vessels in 2019 and 2020 to 14,895 and 14,498, respectively. Once the limit is reached, only DOL sets will be allowed, and all vessels without a DML must return to port.
