Question

write a short note on marine fishery and compost fish culture?

Answer 1

hii frnd .. here is ur ans ...

#Marine fishery: It is the practice of catching fishes in ocean. Mostly marine fisheries are practiced near the coast. This is because harvesting is easier in shallow water depth and also fishes are mostly abundant near the coastal areas as nutrients are abundant there.

#Composite fish culture is a system in which both local and imported fishes are cultured in the same water body. Five or six species of fishes can be grown together in this system. the species are selected in such a way that they do not compete with each other and as well as all the food resources of the pond can be sustainably used. Fishes used in this system are catla, rohu, silver carp, common carp etc.

Nice Question !

Friend !

# Most Marine fisheries are based near the coast.

# This is not only because harvesting from relatively shallow waters is easier than in the open ocean.

# but, also because fish are much more abundant near the coastle shelf, due to the abundance of nutrients available there from coastle upwelling and land runoff.

# The compite fish culture system is the technology developed in India by the Indian council of agricultural research in the 1975s.

# 5 or six species of fishes is used in a single fish pond.
