Effect of developmental stage in cryopreservation of Carp fish Cyprinus carpio L.

Abstract

A total of 60 specimens of common carp Cyprinus carpio L. (40 male, 20 female) were using in present study, ranges between 2 to 5 years, 2 to 5 kg. in total weight for male and 5 to 8 kg. in weight for female. Then preparing the fish for propagation and gain the sex products. A series of experimental processes were conducted to determine the effect of some entrant factors in the cryopreservation of carp embryos, one of these factors was Effect of developmental stage in cryopreservation of Carp fish Cyprinus carpio L . by measurement of Shrinkage period ;Survival ratio and Hatching ratio.
