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.
