Question

WT IS COMPOSITE FISH CULTURE?MINIMUM 3 POINTS!!​

Answer 1

Composite fish culture is simply the fish culture in which two or more  types of fish are cultured collectively.  It is one of the advanced technique for fish culturing.  This is done to get more yield from a pond.

For composite fish  culture only compatible fish can be used because some may not be able to live with other fishes .

Also,  the feeding habits of every fish may be difference from others.

So while choosing the fish keep in mind the variety of the fishes , pond management facilities availability along with food of fishes

                                                OR

Composite fish culture is a system in which 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, 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. 

Answer 2

1. Water quality:

Biological and physicochemical nature of water and their seasonal variations.

2. Drainage:

There should be replacement and recycling facility.

3. Soil quality:

A selected site’s soil in its every 100 gm. should contain 50- 75 mg nitrogen, 6-12 mg phosphorous and 1.5- 2.5 gm. organic carbon. For good production from cultured fish soil pH should be in between 7.5- 8.5.

4. Fish seed:

Availability of quality fish and prawn seed of required species with the transportation facilities to the site and assurance of supply in required time.etc.......
