Abstract

Culture of beluga (HUSO HUSO) in new conditions such as inland BRACKISH WATER necessitates studying nutritional requirements and effects of different diets on gonadic and somatic GROWTH as well as physiological condition. In this research 74 beluga each 4 years old cultured in BRACKISH WATER of earthen ponds in Bafgh Fisheries Research Station, were selected and distributed in 8 circular cement ponds. Feeding was done in 4 formulated diets with fixed protein level and 4 ENERGY levels (400, 425, 450, 475kcal/100g). Samples were biopsied at the start and the end of the experiment to determine sexuality and stage of maturation. To study gonad tissues, the hematoxylin-eosin method was used. Results indicated that somatic and gonadic GROWTH indices were affected by diets. Somatic GROWTH overlapped in both sexes. Sexual maturation stages were not the same in males and females and trarisition from stage II in males was more rapid than females. Considering the results in this study, diet treatments influenced on somatic GROWTH in both sexes and gonadic GROWTH in females. We conclude that somatic and especially gonadic GROWTH in BRACKISH WATER is suitable. Therefore, inland BRACKISH WATER environment can be regarded suitable for beluga cultivation.
