In composite fish culture mark the fish as top feeder(T), mid zone feeder(M) and bottom feeder (B). Fish Feeding (i) Rohu (ii) Common Carp (iii) Catla (iv) Mrigal

(i) Rohu is the one among the Indian species, and it is a mid-zone feeder. (ii) Common carp is a bottom feeder but feeds on all types of living organisms. It is thus an omnivorous species. (iii) Catla is a top surface feeder that feeds on small organisms. These fishes have a straight back that helps their upturned mouth to easily reach the surface and capture the food without being revealed to the prey. (iv) Mrigal is a bottom feeder that feeds on detritus and decaying animal and plant remains.

Match the following. Column I Column II (a) Catla (i) Bottom feeders (b) Rohu (ii) Surface feeders (c) Mrigal (iii) Middle-zone feeder (d) Fish farming (iv) Culture fishery

(a) - (ii) Catla and silver carp are surface feeders. These are freshwater fishes. (b) - (iii) Rohu feed in the middle-zone of the pond, i.e., column feeder. (c) - (i) Mrigal carps are bottom feeders. (d) - (iv) Culture fishery is one of the ways of obtaining fishes. In this, fishes are obtained from fish farming. A culture fishery is a sort of inland fishery that takes place in tiny bodies of water and involves the rearing and harvesting of desired species. In culture fishery, all indigenous fishes are herbivores.
