Question

A pond is being cleaned using a motor pump. During the initial stage of water removal, X fishes are observed. In the later stage, Y fishes are observed. Identify the X and Y.

• A. Grass Carps, Catlas
• B. Rohus, Mrigals
• C. Catlas, Rohus
• D. Grass Carps, Mrigals

Answer 1

The correct option is C Catlas, Rohus

$\bullet$ In composite fish culture a combination of five or six fish species are used in a single fish pond.
$\bullet$Their food habits are different and therefore food available in all parts of ponds is used. E.g., Catlas are surface feeders. Rohus feed in the middle zone. Mrigals and common carps are bottom feeders, and Grass Carps feed on the weeds.
