Shark Depredation and Bycatch in Pelagic Longline Fisheries Page 22 6.1. Industry Attitudes Chapter 6 Industry Attitudes and Practices Table 6.1 summarizes predominant attitudes related to shark depredation and bycatch possessed by fishers of 12 pelagic longline fisheries. The existence of restrictions on shark finning and shark retention limits (Table 4.1) has a large influence on industry attitudes towards shark interactions in the Australia, South Africa, and Hawaii, U.S.A. longline fisheries, where legal constraints have caused shark interactions to be an economic disadvantage. In these fisheries, fishers have a large incentive to avoid shark interactions. In the Italy longline fishery, despite a lack of market for shark products, low shark interaction rates result in low incentive to reduce shark interactions. The Fiji longline fishery attitudes towards shark interactions is unexpected. In this fishery, where almost all caught sharks are finned and carcasses discarded, fishers perceive that costs from shark interactions exceed the economic benefit. In the Chile, Japan and Peru longline fisheries, where restrictions on shark finning and retention are lacking, there is no incentive to reduce shark interactions, as revenue from sharks exceeds costs.

Longline Industry Attitude Pelagic Longline Fishery Australia Tuna and Billfish Fishery Chile Artisanal Mahi Mahi and Shark Fishery Want to minimize shark interaction s due to time required to repair gear and discard sharks Want to minimize shark interactions because revenue from catching sharks is exceeded by costs from shark interactions Little incentive to reduce shark interaction s because they are infrequent and result in nominal costs Want to maximize shark catch because revenue exceeds economic costs from shark interactions Want to minimize shark catch to avoid injuring crew when landing sharks from projectile swivels and shark bites Want to minimize shark fishing mortality because are concerned with overfishing Want to minimize shark catch to make more baited hooks available to more valuable fish species Shark interactions are an expected and unavoidable part of longline fishing X X X X X No incentive to reduce shark interactions because revenue from sharks exceeds costs from shark interactions X X Chile Swordfish Fishery X Fiji Tuna Fishery X X Italy Mediterranean Industrial Swordfish Fishery Japan Distant Water, Offshore and Nearshore Tuna Fisheries Peru Artisanal Mahi Mahi and Shark Fishery South Africa Tuna and Swordfish Fishery X X X X X X X X X X U.S. Hawaii Tuna Fishery X X X X X U.S. Hawaii Swordfish Fishery X X X X X
