Question

name the fishes used in composite fish culture according to their columns​

Answer 1

Answer:

A single species of carp culture in a pond is known as mono-culture and previously this mono-culture was the normal practice in many of the countries. Hence there was a small production of 300-600 kg of fishes per hectare of water in a pond. Subsequently there is a great change in the process of carp culture. Instead of single species, more than one species of major carps have been selected for rearing and culture in the same pond. They are living in the different water levels as well as they have different feeding habits. This process of rearing of fishes is known as composite fish culture. Recently three exotic carps such as silver carp, grass carp and common carp along with the three Indian major carps are selected for composite carp culture in the Asian countries. Thus the composite fish culture or composite mixed culture of six species is now introduced in the same pond. They are to be reared scientifically so that there will be very good production of fishes. To achieve this, appropriate amount of supplementary food as well as manure are to be supplied timely.
