Net fishing is a method of catching fish using a large mesh net. Fishermen deploy these nets in various ways, such as casting them from a boat or dragging them along the sea floor. The design of the net allows fish to be trapped while minimizing the escape of smaller or unwanted species. This technique can be used in both freshwater and saltwater environments. Different types of nets, like gill nets and trawl nets, are used depending on the target species and fishing conditions. Net fishing is an important practice for commercial fisheries and local communities relying on fish for food and income.
