Abstract:

Experiments were conducted to evaluate decapsulated  Artemia  cysts as food for  Salmo trutta caspius  fry. Initially, The larvae Mean wet weight 16.1 ± 78 mg were fed on different diets :(T1) dried decapsulated Artemia cysts, (T2) decapsulated  Artemia  urmiana, (T3)  Artemia urmiana  nauplii,(T4) artificial feed feeds for  51 days.After this period, all treatments were fed with commercial diets  for 02days.At the end of  the first period, larval treated fish T2 (feed with Nauplii Artemia) of WG, LG, percentage of body weight gain, SGR, dry weight and survival were better than the other treatments (p <0.05). In the end of second stage after 20 days in treatments T2 and T3 had the highest wet weight (p <0.05), the highest dry weight and length were obtained at treatment T3 (p <0.05), The highest percentage increase in body weight in the treatments T1 and T3 respectively (p <0.05). In all treatments there was no significant difference in SGR and survival (p <0.05). This study showed that the larval Caspian Sea salmon have growth and better performance in use of Artemia Nauplii.
