According to the recent study carried out by the team of international researchers, led by Dr Jeffrey Mangel from the University of Exeter, the number of birds caught in gillnets during fishing can be dramatically reduced by attaching green battery-powered LED lights.
The study had the researchers compare 114 pairs of gillnets which were anchored in fixed positions at sea and designed to snare fish by the gills in fishing waters off the coast of Peru.
The inventive study carried Sechura Bay in northern Peru; saw the LED lights attached at regular intervals to commercial fishing gillnets which are anchored to the bottom of the water. From late afternoon until sunlight, the nets are left in situ when the fishermen collect their haul.
The result showed that the nets attached with the LED light caught 85 per cent fewer guanay cormorants which is a native diving bird. This bird generally becomes entangled in nets as compared with those without LED lights.
Additionally, as per previous research conducted by the same team, it showed LED lighting also reduced the number of sea turtles caught in fishing nets by 64 per cent. According to the researchers, the lights offer a cost-effective, reliable and durable way to drastically reduce the capture and death of birds and turtles, without affecting or reducing the intended catch of fish.
