PRELIMINARY STUDY REGARDING THE EFFICIENCY OF DIFFERENT HORMONES ON PIKEPERCH SPERMIATION
Keywords:
pikeperch, hormones, spermiationAbstract
The aim of this study is to test the efficiency of different hormones on pikeperch
spermiation and to establish a protocol for obtaining a high quantity of milt. Sixteen
clinically healthy adult pikeperch males (3-4 years old) were used in our
experiments. They were intraperitoneal injected with one of the following hormones:
human chorionic gonadotropine - hCG (Pregnyl), GnRH analog (Receptal) and
carp pituitary extract (CPE). These hormones were injected following two
experimental protocols. The main differences between these two protocols are the
number of stripings after the first injection (1 and 2 for the 1st protocol and the 2nd
one, respectively) and the moment of thermal stimulation. The best results in
stimulating spermiation were obtained with hCG and CPE. The protocols applicable
for milt collecting in pikeperch males must include a thermal stimulation period.
