Bycatches

In this image, guitar fish, rays and other bycatch are thrown overboard from a shrimp boat in the Gulf of California. There has been efforts to reduce bycatch. In some cases thr efforts are beginning to pay off. In some places they now use a better design of hooks and nets, the have pingers on the nets to repel marine mammals. They even have streamers on the back of the boat to scare away seabirds so that they do not get caught.

Trawling

In this image from National Geographic, it shows everything that was caught by trawling in Mexican waters. Out of everything in this image, the only thing to be used and sold will be the shrimp. Everything else will go to waste.
