Abstract
Rainbow trout (Oncorhynchus mykiss), the main species of fish breeding in Iran is that the cellar every year in different breeding centers, which are the artificial propagation. The amplification process, various factors such as extraction of selected female egg, the sperm quantity and quality of male broodstock, is involved in this study, the ionic composition of the sperm of male broodstock rainbow trout and their relationship with the efficiency of artificial reproduction, the was investigated. 15 samples from male broodstock in five pieces so that a 3 year, 5-year segment 4 and 5 had a 5-year mean and standard deviation of ionic compounds in fish, 3, 4 and 5 years were evaluated in Na: 25.4 ± 207.02 meq/l, 36.72 ± 184.98 meq/l and 37.97 ± 176.96 meq/l, K: 7.01 ± 20.23 meq/l, 4.8 ± 19.36 meq/l and 5.17 ± 17.48 meq/l, Ca: 2.24 ± 8.56 mg/dl, 1.39 ± 5.42 mg/dl and 2.4 ± 5.04 mg/dl, P: 0.5 ± 1.54 mg/dl, 1.47 ± 2.08 mg/dl and 0.93 ± 1.83 mg/dl, Mg: 0.09 ± 2.04 meq/l, 0.13 ± 1.982 meq/l and 0.16 ± 1.98 meq/l, respectively. Curiously, the relationship between potassium and the percentage of larval survival, positive, Vartbat between magnesium fertilization rate, percentage of the stroke, the percentage of hatching and larval survival, positive, and the relationship between phosphorus, sodium percentage (fertilization and hatching of eye protrusion) and negative images were obtained.
