Summary
The authors tested the effectiveness of using green light emitting diodes (LEDs) on demeral, set gillnets in Constante, Peru as a visual deterrent to reduce seabird bycatch. When comparing illuminated nets to control nets, seabird bycatch was significantly lower and represented an 85.1% decline in guanay cormorant ((Phalacrocorax bougainvillii) bycatch. Target catch was not affected, suggesting that this mitigation technique may be an effective mitigation method for seabirds, the same way it seems to be effective for reducing sea turtle bycatch.
