Tangent Contribution in the Increase of Efficiency of Carp’s Reproduction Technology Through in vitro Fecundation Method

Abstract

The influence of the BioR preparation on some indices of sperm quality, spawn fertilization ability and early embryo development of carp under the conditions of in vitro fertilization was studded. During the experiment there have been chosen ordinary carp (males and females at the age of 5-6 years) used in carp artificial reproduction sector. The injection of BioR to reproductive carp in the period of preparation for artificial reproduction contributed to: -a significant increase of sperms longevity after collection; -moderate improvement of seminal cells mobility after collection in the experimental group by 5.53 % versus the control group; -the increase in seminal cells survival under conservation conditions for a short period of time at temperatures 0- +4° C. BioR favours in vitro fertilization results by improving functional indices of the seminal material, as well as spawn biological value
