Little Fishy Life Saver

To reduce overfishing and help maintain the ocean’s ecological balance, the Little Fish Protector was developed to prevent the problem of bycatching (the accidental capture of untargeted species). The device works by emitting sound waves to herd non-target fish schools away from nets and major fishing areas. Though it doesn’t detect species itself, the stringed, floating units can be deployed by experts and fishermen within minutes to deter unwanted catches and preserve homeostasis.

Designers: JiaChen Du, GuangHao Wu, WenZai Ye, Jooyoung Joen
