To save the world fisheries from depletion, shrimp trawlers need to reduce unwanted extra catches. To find an answer to this problem, here are the innovative fishing nets with ‘exit holes’ being introduced. Using it can reduce extra catches to 70 percent! This is revealed by a U.N. study on Sunday.
The new trawler nets have metal grilles, letting only shrimp through into the main bulb-shape net. But, it stops bigger fish or turtles, forcing them out through an “exit hole” in the side.
The otherwise, generally used fine-mesh nets also scoop up everything from tiny fish to sharks and turtles, and these usually end up discarded dead.
The 12 tropical-nation-project includes Mexico and the Philippines. And, they are said to have dramatically cut the unwanted catch of young fish, turtles and other ‘by-catch’ by as much as 30 to 70 percent! The U.N. Environment Programme informed this in a statement.
