Jun 7, 2019 · Scientists are testing nets illuminated with LED lights to see if increasing net visibility reduces sea turtle bycatch in gillnet fisheries. Gillnet fisheries operate by suspending a wall of netting in the water column.

Jan 27, 2022 · Research of the past 10 years has shown that gillnets illuminated with lights ward off sea turtles. They can see the nets and veer away. But the effects of illuminated nets on other vulnerable species, total bycatch and how they affect fishing have never been tested.

Jul 11, 2018 · We assessed the effectiveness of illuminating fishing nets with green light emitting diodes (LEDs) to reduce the incidental capture of seabirds. Experiments were conducted in the demersal, set gillnet fishery of Constante, Peru and compared 114 pairs of …

May 1, 2023 · The results were: (1) The number of fish caught at a distance of < 1 m and at a distance of 1-2 m, this proves that many fish are attracted to light (positive phototaxis); (2) Proven by gill...

Jan 25, 2022 · In a new study, a research team has discovered that using gillnets illuminated by LED lights greatly reduces accidental bycatch of sea turtles, rays, sharks and other fish, Wildlife Conservation Society (WCS) reported. Furthermore, the market value and catch rates of targeted fish were not affected by the lighted nets.

Feb 28, 2022 · Senko et al. find that illuminating gillnets with green LED lights reduces total discarded fisheries bycatch biomass, which includes decreases in elasmobranch, Humboldt squid, and unwanted finfish, without compromising target fish catch or value. Illuminated gillnets also reduce the time it takes fishers to retrieve and disentangle nets.

Jul 11, 2018 · According to scientists from the University of Exeter, an estimated 400,000 diving seabirds die annually by getting caught in gill nets intended to catch fish.

Dec 9, 2019 · Researchers at the University of Exeter and the Peruvian conservation organization ProDelphinus have found that installing LED lights on top of floating gill nets can greatly reduce the likelihood of accidental capture of protected species.

We assessed the effectiveness of illuminating fishing nets with green light emitting diodes (LEDs) to reduce the incidental capture of seabirds. Experiments were conducted in the demersal, set gillnet fishery of Constante, Peru and compared 114 pairs of control and illuminated nets.

Nov 8, 2019 · We examined the potential effectiveness of 3 visual cues-shark shapes placed along the length of the gill net, illumination of nets by LED lights, and nets illuminated with chemical...
