How does the fishing net work?
A mesh-like net is cast and pulled through the water. As the net moves through the currents, fish are collected inside. The net is then pulled out of the water and the entrapped fish are removed. The fisher uses the pole to drag the net through the water and collect fish.
How do you measure a fishing net?
For sizing the right net, measure the hoop on your net, width first then length(end of pole to outer-most edge of hoop), those two numbers should not be larger than the size of net you’ll need.
Why is commercial fishing bad?
It can change the size of fish remaining, as well as how they reproduce and the speed at which they mature. When too many fish are taken out of the ocean it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals.
What fish are caught with nets?

A bottom-set gillnet can be used in rivers, lakes or the sea. You should use it when you know that the fish you want to catch live on the bottom or near to the bottom. It is hard to use if the bottom is too steep, too deep or too rocky. Almost any size of boat can be used to fish with these nets.
Is a cast net a gill net?
The gill net mesh size allows a fish of the proper size to fit its head and gills through the net, but not its body. When the fish attempts to pull out of the net, it becomes “gilled” or stuck by its gills. A cast net is a cone shaped net with a weighted perimeter that is thrown by hand.

Do fish suffer when caught?
Catch-and-release fishing is seen as a harmless hobby thanks in part to the belief that fish do not experience pain, and so they do not suffer when a hook pierces their lips, jaws, or other body parts. But research increasingly shows that these beliefs are incorrect.
