Abstract :

This study was accomplished during the period of breeding and migration of the kutum (2015) to the Shirud River (Tonekabon, Iran) on 60 male and female broodstocks. During this study, the relationship between total length and weight of adult males and females broodstocks with the reproductive parameters such as the number of eggs per gram, egg weight, egg diameter, number of larvae produced in gram, the weight of larvae produced, and the fertilization rate have been measured. According to Pearson correlation test, results showed that there was a negative significant correlation (P
