Effects of Daphnia magna and Artemia nauplii on growth performance in Persian sturgeon Acipenser persicus larvae
This study was carried out in a completely randomized design 3×3×4 factorial arrangement in three periods of rearing in spring 1997. Density of 300 larvae was assigned for each oval tank with 0.1m2 surface area, 30cm deep, a volume of 20lit and 0.25 lit/min of water flow per minute at Shahid Rajaie fish breeding and culture center in Sari, north of Iran. The fries were divided into ...

متن کاملEffect of Dietary Estradiol 17 on Growth, Hematology and Biochemistry of Stellate Sturgeon Acipenser stellatus
The effects of oral administration of different doses of estradiol-17 (E2) were examined on the growth performance, body composition, sex steroids, blood indices and histology of liver and gonad in Acipenser stellatus juveniles. Five-months-old fish (40.9 ± 1.1 g) were fed 0, 25 and 50 mg E2 kg diet for 210 1 days. Results showed that increasing doses of E2 caused reduce growth rate. No signifi...
متن کاملFertilizing ability of cryopreserved spermatozoa in the Persian sturgeon (Acipenser persicus) and stellate sturgeon (A. stellatus)
Motility of spermatozoa was studied on 12 and 7 specimens of Acipenser persicus and A. stellatus, respectively. The density measured to be 2.22±0.65x109ml-1 in A. persicus and 2.21±0.55x109ml-1 in A. stellatus. Semen samples were diluted with two extenders containing tris 118mM, sucrose 23.4mM, pH=8, egg yolk (20%), dimethyl sulfoxide (15%) and penicillin potassium (500IU/ml) and biociphus exte...
