Abstract :
Abstract Rainbow trout (Oncorhynchus mykiss), is the one of the main species of cool water fishes in Iran that each year in different centers of reproduction, have the artificial reproduction. In procedure of reproduction, different factors such as extraction of selected females breeding stocks eggs, the sperm quantity and quality of male breeding stocks, the biochemical and ion composition of sperm from male breeding stocks rainbow trout and their relations with the efficiency of artificial reproduction, were investigated. In 15 samples from male breeding stocks so that 5 pieces of 3 years, 5 pieces of 4 years and 5 had a 5-year. Mean and standard deviation of biochemical compounds in fish 3, 4 and 5 years were investigated. Relationship between albumin, alkaline phosphatase, urea, triglycerides and cholesterol, with multiplication factors of efficiency, were direct, and between creatinine with the efficiency of amplification, was negative. Relationship between total protein with fertilization rate, was negative, but with percentage of protrusion of the eyes, the percentage of hatching, larval survival rate were positive and direct. While relationship between glucose with the percentage of fertilization, was positive, but with percentage of protrusion of the eyes, the percentage of hatching and larval survival were negative.
