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 OR 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 correl...

| description | A study was conducted on the effects of egg size OR 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 (P<0.05). There were positive and significant correlation between egg size and weight of prelarvae at hatching stage (P<0.05), but at 10days post hatching differences were not significant (P>0.05).
There were also positive and significant correlation between egg size and volume of yolk sac at hatching (P<0.05)but during yolk sac absorption, differences decreased gradually and volume of yolk sac at. 10 days post hatching were equal. Survival rate at yolk sac absorption stage increased with increasing of egg size but differences were not significant (P>0.05). However, during the first feeding stage the correlation between egg size and survival was very weak. |
