well as brackish water fisheries.

 Some of the inland fish varieties are as follows:

Rohu

Mrigal

Catla

Silvercarp

 Inland fishery is of two types- capture fishery and culture fishery.

Composite fish culture
 Intensive fish farming can be done in composite fish culture system. Both local

and imported fish species are used in such systems.

 In such a system, a combination of five or six fish species is used in a single
fishpond. These species are selected so that they do not compete for food

among them having different types of food habits.
 As Catlas are surface feeders, Rohu feeds in the middle zone of the pond, Mrigal

and Common Carps are bottom feeders and Grass Carps feed on the aquatic

weeds.
