Answer 1

The correct option is A Statements 1, 2, and 3 are correct.

Composite fish culture is an indigenous system developed by the Indian council of agricultural research.
It involves a combination of five to six species of fish and all are cultured in a single pond.
Fishes are selected in such a way that they have different food habits and do not compete with each other.
As a result nutrients present in all levels of the pond are used up.
Usually, fishes like Rohu, Catla, Mrigal, Grass carp, and Chinese carp are used. This increases the per hectare production of fish.
