Abstract
A total 48 Cyprinus carpi breeders (W = 963 +/- 9.5 g; L= 33.60 +/- 2.6 cm) were divided into two groups as control (n=24) and experimental (n=24). Control group spawned naturally while experimental group were subjected to induce spawning using ova prim. Results showed positive correlation in breeder's body weight, gonad somatic index (GSI) and fecundity. Significantly high (P<0.01) fecundity and % hatch is observed in induced spawning as compared to control (open water). In an other experiment 84,000 C. carpi larvae after alluvial stage were grown on 100% body weight spread in two feeds on powdered egg yolk, beef extract, liver extract and live food for 35 days. Stocking density was kept 7,000 larvae per tank in triplicate for each feed. Growth was observed as beef liver extract > beef extract > open water > egg yolk. Maximum survival (57%) was noted in liver extract feed and minimum (25%) in pond water.
