The Prospect and Feasibility Assessment of Brine Shrimp （Artemia franciscana） Culture in Bangladesh

A laboratory-based work was conducted on development, biometry （cyst diameter, hatching efficiency and hatching percentage） and survival rate of Artemia franciscana at 35 ppt using natural brine water under constant aeration facilities. The experiment was carried out for both chorionic and decapsulated cysts. There was a significant increase in hatching output of the decapsulated cysts than the chorionic cysts. The survival rate was counted only for the chorionic cysts because nauplii hatched from decapsulated cysts died after four days of incubation before reaching the adult stage. Untill now the Artemia cysts are imported from abroad. Though the prospect of mass production of Artemia in Bangladesh is feasible but there needs to be more studies done.
