Abstract

Cross-breeding of GRASS CARP and BIGHEAD CARP resulted into viable hybrid. Artificial propagation was induced by I.P. injection of LRH-A. Percentage of egg fecundity, hatching ratio and active swimming larvae were found to be 88%, 90% and 90%, respectively. Larval development of hybrids during incubation was normal and nearly identical to other Chinese carps until the fifth day. Then they were transferred into 400 m2 ponds for further rearing. The high mortality rate of 60% "vas observed in the first day of feeding, due to the failure in development of gill and mouth of hybrids. During the early life stage, the larvae were zooplankton feeder and then turned to a mixed phyto-zooplankton feeding regime and finally after day 48 were completely phyto feeder. Morphological analysis on color, scales, structure of fins, mouth, body shape, body length, vertebral bones, body ratios and the form of pharyngeal teeth of the hybrid showed significant differences with control fish. Furthermore, blood smears of hybrids indicated different shape and cell volume in the erythrocytes in comparison with control. Chromosomal preparation also indicated that the majority of hybrids were TRIPLOID (2n=72) as well as some diploid (2n=48) whereas both the GRASS CARP and BIGHEAD CARP were totally diploid with 2n=48.The proximate analysis results of hybrids meat showed different amount in protein, fat and ash with control, too.
