write few paragraphs describing the topic fish farming.

Dear student,This is an activity based question which should be answered by you. Following are some of the points which might help you.Fish farming refers to the raising of aquatic animals such as fishes for human use. These fishes are basically reared in tanks and ponds and are sold out commercially for human consumption. An intensive way of farming fishes is the composite fish culture system. In such a system, five or six different species of fishes are grown together in a single fishpond. Fishes with different food habitats are chosen, so that they do not compete for food among themselves. For example, catlafeed on the surface of water, rohu are middle zone feeders, mrigal and common carp are bottom feeders, and grass carp feed on weeds. This ensures complete utilization of food resources in the pond. Such a system increases the fish yield. A major problem with this system is that many of these fishes breed only during monsoon. However, the use of hormonal stimulations has provided a solution for this problem.The ways of increasing marine fish farming are as follows: 1)Yield of marine fishing is increased by locating large school of fishes using satellites and echo sounder. 2) Marine fishes of higher economic value are farmed in seawater. 3) Marine fish farming is increased because of using aquaculture methods.
