Question

what is composite fish culture. explain with an example.
​

Answer 1

Answer:

Composite fish culture is a method in which five or six different types of fish species are grown together in a single fish pond. Fish with different food habitats are selected so they don't fight with each other for food. This guarantees that the food supplies in the pond are completely utilized.

Answer 2

Answer:

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.

● For example: 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 now they will not compete for the food. The problem was that most of these fishes breed only during rainy season. Hence the obstacle is to collect good quality seed, so that it can be collected and mixed with other species as well. To solve this problem hormonal stimulation is performed which involves the activities that lead to the maturation of the fish sex cells to breed these fishes in pond.
