Spawning Latency Period in Hormonal Induced Reproduction of Pikeperch (Sander Lucioperca)
Keywords:
hormones, latency, pikeperch, spawningAbstract
The aim of the study was to assess the spawning latency period in the hormonal induced reproduction of pikeperch. Spawners were injected with human chorionic gonadotropine - hCG (Pregnyl. Prior to the intraperitoneal injection, eggs were sampled to establish the maturation stage of oocytes. Females were stimulated with a single hormone dose of hcG (600 IU kg–1) and males were stimulated with a dose of 300 IU kg–1. There is a large variance in the spawning latency time of pikeperch.
