Fishing gear modifications to reduce elasmobranch mortality in pelagic and bottom longline fisheries off Northeast Brazil



Target catch: 

tuna (pelagic) and sharks (bottom)

Study Type: 

Field study in the wild

Effect on target catch: 

None reported for pelagic longlines. On bottom longlines, CPUE was higher for blacknose and nurse sharks and southern stingrays; no CPUE difference between hook type; more tiger and blacknose sharks were alive at haulback with circle hooks

Effect on bycatch species: 

CPUE was significantly higher for night, blue, silky, and oceanic whitetip sharks on circle hooks.
