It turned out that it is possible to protect marine life and improve the efficiency of net recovery just by turning on the LED light on the net used for fishing.

In net fishing such as purse seine fishing and gillnet fishing, ' bycatch ' occurs in which a large amount of inedible fish and sea turtles are caught at the same time as edible fish, which adversely affects the ecosystem and increases the time required for sorting. Problems such as have been pointed out. A research result was reported about fishing using such nets, 'It is possible to reduce bycatch by attaching LED lights to the nets.'

In net fishing, there is a problem that inedible fish such as sharks and organisms designated as endangered species such as sea turtles, marine mammals, and seabirds are also landed, and this problem affects the ecosystem. It has been pointed out that it is out.

A research team led by Jesse Senko, who studies ecological conservation at Arizona State University, installed LED lights on the nets used for gillnet fishing to develop solutions for bycatch and tested their effectiveness.

As a result of gillnet fishing in Baja California Sur , Mexico using nets equipped with LED lights, we succeeded in reducing bycatch by 63%. Of these, sharks and rays were reduced by 95%, Humboldt serrata by 81%, and fin whales by 48%. In addition, it took about half the time to collect the net with the LED light attached. From this result, the research team states that attaching LED lights to the net has specific benefits for fishermen.

The Association of Wildlife and Humanities also said, 'Traditional methods of preventing bycatch could affect catches and have a significant impact on food security. The results of this study faced an endangerment. It provides an effective means of saving fish and will be scrutinized by the Association of Wildlife and Human Resources as part of its global conservation efforts. '
