Using of nutshell pomegranate, Alum Solution to remove adhesive substance from common carp ( Cyprinus carpio ) Eggs during artificial reproduction.

Abstract

This study hael been established in aheatchary private / Babylon province from 9 April to 25 April 2011, in order to study the possibility tannins substitute (which is used in artificial propagation for elimination of adhesive substance from eggs of Cyprinus carpio ) by alum solution or grenacle punnic granetun and their effects on both hatching and fertilization. Four different concentrations of punnic granetun ( 1, 2, 3 and 4 ) g/L and another four concentrations of alum solution ( 0.5, 1, 1.5 and 2 ) g/L with acontrol solution ( 0.5 g/L Tannin ) for each experiment at 3 replicutes . The Results showed that there is not signefcet differente ( p < 0.05 ) between punnic granetum 2 g/L and control solution wherease averages of hatching ratio ( %70.97 ) ، ( % 71.09 ) respectively also there is not any scgnificat between alum solution ( 1g/L ) and the control solution ( %71.41 ) , ( %70.88 ) respectively for hatching ratio, that is mean they are the best to use in stead of tannins solution.
