How does the otter trawl work?

Homework Answers

Answer #1

Answer: Otter trawl is employed for harvesting fishes or shrimps. It is mostly used to capture the creatures the dwells at the bottom of the sea. It uses a large net which is tied to a boat with help of big ropes. This net has an open mouth just like a carry bag. One side of a net which touches the bottom of the sea contains specialized gears which help net to move at the bottom easily. Imagine you have tied a very big carry bag to the end of the boat with big ropes and thrown it into the bottom of the sea. Now when the boat starts moving forward into the water this net starts moving at the bottom into the water and starts capturing the fish that comes inside the net because of the dragging force. After some time net is pulled at the surface of boat and fishes can be separated from the net.
