Circle Hook Program

The Sea Delight Circle Hook Program

The introduction and use of circle hooks in our programs has been fundamental for the success of the following efforts:

Yellowfin Tuna Fishery in Indonesia
Wild-caught Yellowfin Tuna, Handline and Longline Fishery in Vietnam

Recent studies show that the use of circle-shaped hooks instead of the traditionally used J-shaped hooks can significantly reduce the bycatch of turtles in longline fisheries. Whereas the use of a J hook increases gut hooking, research show that the shape and point of the circle hook is designed to prevent deep-hooking and to only hook in the corner of an animal's mouth; thus making it easier to remove. Circle hook also decreases deep hooking as they are less likely to be swallowed by turtles. When ingested J-shaped hooks can cause suffocation or internal bleeding

The Sea Delight Ocean Fund is both committed to supporting circle hook trial programs, as well as providing adequate training and tools for proper handling and release of turtles accidentally hooked. The use of circle hooks is a tool which helps improve responsible fishing practices while significantly reducing incidental catch (bycatch) of marine turtles without impacting fishing activity.
