An illuminating idea to reduce bycatch in the Peruvian small-scale gillnet fishery.

Study Type: 

Field study in the wild

Location: 

San Jose, Salaverry, Ancon, Peru

Target catch: 

Elasmobranchs, tuna, dolphinfish

Effect on bycatch species: 

Bycatch probability per set was reduced by up to 74.4% for sea turtles and 70.8 for small cetaceans in comparison to non-illuminated nets. For seabirds, nominal BPUE decreased by 84% in the presence of LEDs.

Effect on target catch: 

No effect

Final report to the New England Aquarium on pinger displacement trials for Ganges River dolphins Platanista gangetica in the Sundarbans mangrove forest, Bangledesh

Study Type: 

Field study in the wild

Location: 

Bangledash

Target catch: 

N/A

Effect on bycatch species: 

Subtle differences in dolphin behavior were detected but it remains unclear if pingers would successfully reduce dolphin interactions with gillnets.

Acoustic investigation of bycatch mitigation pingers

Study Type: 

Field study in the wild

Location: 

Queensland, Australia

Target catch: 

Shark

Effect on bycatch species: 

The current net/pinger configuration is adequate for humpback whales, dugongs and dolphins swimming at normal travelling speeds. The current pinger spacing is insufficient for dolphins swimming straight at the net at high speeds.
