Question

what is composite fish farming ? how are fishes select this farming ? explain with ex

Answer 1

In composite fish culture, a combination of 5 to 6 species is used in a single fishpond.These species are selected so that they do not compete for food among them having different type of food habits.As a result,the food available in all the parts of the pond is used.As catlas are surface feeders, rohus feed in the middile-zone of the pond,mrigals and common carp are bottom feeders,and grass carps feed on the weeds,toghether these species can use all the food in the pond without competing with each other.This increase the fish yield from the pond.

Answer 2

Composite Fish Farming or Polyculture Of Fish is the type of fish culture in which fast growing compatible species of fishes are selected, so that, there is little competition between them and all ecological zones are exploited for achieving maximum yield.

1. The Silver Carp is a SURFACE FEEDER.
2. The Rohu feeds in MIDDLE ZONE.
The Mrigal is a BOTTOM FEEDER
