The Reproduction Biology of Rainbow Trout (Oncoryhynchus mykiss) in the Gürün Gökpinar Fisheries Station Conditions

Mehmet KARATAŞ

Abstract

Fecundity, maturity age and spawning time were determined for Rainbow trout (Oncoryhynchus mykiss) living Gürün Gökpinar conditions. The majority of males begins to mature at an age of 2 years in Gürün Gökpinar conditions. Females were mature at an age of 3 years. The main spawning period for Rainbow trout in Gürün Gökpinar conditions would appear to be within the months of December and January, though a small number of ripe fish were appeared the end of November. The egg yields of Rainbow trout in the 2.3.4 age groups were found as 2383 egg/kg, 1872 egg/kg and 1716 egg/kg respectively.
