Examination of Sperm Viability and Egg Fertilization Rates in Trout (Oncorhynchus mykiss) Breeding

Abstract

The purpose of this review is to investigate various methods used to extend sperm viability and increase egg fertilization rates in trout. It aims to identify effective sperm protection and fertilization rate increasing strategies to increase variation in trout variation. Sperm samples taken from trout were examined with different preservative solutions and storage conditions. Sperm viability conditions and fertilization rates were compared using Cortland solution and other preservative solutions. Findings obtained through analysis show that some preservative solutions and storage methods significantly increase sperm survival time and egg fertilization rates. It has been observed that Cortland solution, in particular, is effective in prolonging sperm viability and increasing fertilization rates. The possibility of applying effective methods to increase the viability of trout sperm and the prolongation of fertilization and the positive effects on trout production are being investigated. Guidance for practical suggestions and changes is recorded.
