UV lights reduce turtle bycatch
July 24, 2013
Researchers have devised a simple but effective way to reduce the number of turtles accidentally caught by fishing nets: Illuminate the nets with ultraviolet lights.
When fishing boats gather fish such as flounders, they often pick up sea turtles as well. This bycatch is “a barrier to the recovery of sea turtle populations,” researchers write in Biology Letters. But they note that green, loggerhead, and leatherback turtles can detect UV light — a capability that sets them apart from some fish species.
The team attached UV LED lights to floatlines and tested them around Punta Abreojos and Bahia de los Angeles, Mexico. The lights cut the amount of turtle bycatch by 40 percent, the researchers found. The technique didn’t appear to scare fish away: In a commercial gillnet fishery, the number of target fish caught by nets with and without UV illumination didn’t significantly differ. The team performed their tests at night, so the next step is to try the UV lights during the day. — Roberta Kwok

WHY TURTLES NEED MOOD LIGHTING “A teenager studied satellite imagery to show how the regulation of beachfront lighting has influenced a resurgence in nesting sites over the past 20 years.” [TakePart]
Tens of thousands of sea turtles are caught each year by small-scale fishers off South America’s Pacific coast, new research shows. Surveys at 43 harbours in Ecuador, Peru and Chile reveal that gillnet fisheries catch more than 46,000 sea turtles per year, with more than 16,000 killed in the process: here.

Yes, it probably should be applied everywhere where there is a turtle bycatch problem.
