Abstract

SPAWNING TIME AND SPAWNING TIME REPEATABILITY OF RAINBOW TROUT (Oncorhynchus mykiss)

This study was conducted in farm conditions in order to reveal the distribution of spawning time and spawning time repeatability in rainbow trout. The spawning times of 48 farms in Eastern Blacksea Region of Turkey were analysed. Separately, the broodstocks of two farms, selected from these farms, were spawned individually and marked group by group according to spawning time/party. Therefore, one year later, when these fish spawned, their spawning characteristics were determined. It was determined that spawning time of rainbow trout showed a distribution between September and May in the region, and in (70%) of these farms spawning continued between December and March when egg strip was performed. Furthermore, it was found out that the rate of repeatability of spawning time was high in one year later (incoming year). When compared with former year, it was found out that rainbow trout spawned 15 days earlier or later.
