BRDs can assist with the on-deck release of bycatch species, such as sharks and mobula rays. These tools can improve crew safety and speed up the release of vulnerable species, enhancing their chances of post-release survival.
BRDs range from simple, low-cost designs to more sophisticated, mid-cost tools, and they can be adapted to suit the characteristics of any vessel. Below, we present the most common ones used on tropical tuna purse-seine vessels.
