Effects of egg size on length, weight, growth and survival of prelarval and early feeding stage of Persian sturgeon (Acipenser persicus)
A study was conducted on the effects of egg size on length, weight, growth and survival of prelarval and early feeding stages of 19 female breeders of Persian sturgeon. The results showed that egg size can affect the total length and weight of prelarvae and there were positive and significant correlation between egg size and total length of prelarvae at the hatching stage and at 2,4,6,8 and 10 days post hatching (P0.05). There were also positive and significant correlation between egg size and volume of yolk sac at hatching (P0.05). However, during the first feeding stage the correlation between egg size and survival was very weak.
