list different types of fish cultures explain composit culture with example & also write the advantages?

Fish farming is the practice of raising fish population commercially. It involves the production of aquatic animals, which are of high economic value like prawns, fishes, lobsters, crabs, shrimps, mussels, oysters etc.

There are two ways of obtaining fishes:

  • Capture fishing is the process of obtaining fishes from natural resources

  • Culture fishery is the practice of farming fishes

Farming can be done in both fresh water (such as rivers, ponds etc.) and marine ecosystems.

For composite culture  please refer to the answers provided by Ishan.

  • Fish culture can be practiced either separately for different fishes or as composite fish culture system. In composite fish culture system, five or six different species of fishes are grown together in a single fish pond. Fishes with different food habitats are chosen, so that they do not compete for food among themselves. For example, catla feed 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.

Fish Culture Practices  
Pond can be classified as monoculture or polyculture.
1. Monoculture:    This is the practice of culturing only one species of fish 
in a pond unit (Fig. 2a).  Under monoculture, a farmer may grow only Clarias 
in the pond.  He will be able to know more about the management of Clarias 
than other fish species. 8
2.  Polyculture:  This is the practice of culturing more than one species of fish 
in the same pond.  Fish yield under polyculture (Fig. 2b) can be higher and 
foods in the pond properly utilized, since the different fish species exploit 
food at different trophic levels.
uses of composit culture
  • food available in all parts of the pond is consumed by all the fish.
  • they have different food habits.
