How many turtles are killed by bycatch?
Bycatch Victims It is estimated that 300,000 small whales and dolphins, 50 million sharks and rays and 250,000 turtles die annually as bycatch. Many of these animals are keystone species, which means they play a crucial role in their ecosystem. As a result, ecosystems may collapse without them.
Which has the highest rate of bycatch?
Shrimp trawling They found discard rates (bycatch to catch ratios) as high as 20:1 with a world average of 5.7:1. Shrimp trawl fisheries catch two percent of the world total catch of all fish by weight, but produce more than one-third of the world total bycatch.

What animals are affected by bycatch?
Bycatch can negatively affect species such as dolphins, sea turtles, protected fish, and whales by harming animals, contributing to population declines, and impeding population recovery. Other impacts of fisheries on marine mammals may include removal of their preferred prey and sometimes habitat damage.
