Descripción

Decapsulation of brine shrimp eggs was originally carried out with sodium hydroxide and sodium hypochlorite at the Chacheongsao Fisheries Station. The cost of decapsulation by that technique was estimated at B300/kg. of brine shrimp eggs. A modified technique has been developed whereby decapsulation is conducted by using calcium oxide and calcium hypochlorite as stimulating agents. Promising results were achieved with the same degree of success as with the former technique. However, the latest t echnique is better because the cost of decapsulation can be reduced from B300/kg. to only B18/kg. of brine shrimp eggs.
