Abstract
In order to check the survival and growth rate of Stellate sturgeon (Acipenser stellatus) in a one-month growth period, 1200 Stellate sturgeon fish fry weighing 0.5 to 10 grams in different salinities from 0 to 13 parts per thousand in 12 fiberglass tanks 2 tons were (Water height 50 cm) tested. During the experiment, the fish were fed with live food, preferably daphnia, gammarus, and sea nereis worms 6 times a day. Tanks were siphoned and water changed every day. The water temperature of the ponds along with sea and well water temperature, dissolved oxygen level and pH level were measured daily. During the test period, daily losses were collected and recorded. The results showed that in the weight range of 0.5-5 grams, the percentage of survival was better in lower salinities, but the percentage of survival in the weight range of 5-10 grams was equal in different salinities. According to the results, it is suggested that the fish fry from Stellate sturgeon first be released in the river mouth in a salinity of less than 8 parts per thousand and then enter the sea after adapting to the salinity.
