The effect of sodium sulphate, aluminum hydroxide and aluminum acetate on capsule remover Artemia cysts (Artemia franciscana)

Abstract

Artemia Cyst is a kind of live food which has external hard cuticle which should be de membrane before usage. Artemia Cysts membrane can be eliminated with the use of capsule remover. In this study, in order to determine the most effective capsule remover, Cysts (Artemia franciscana) were primarily exposed to 8%, 16%, and 24% levels of chemical material including Sodium sulfate (Na2So4), Aluminum hydroxide (Al (OH) 3) and Aluminum acetate (AlC2H5O4) respectively for 10 minutes and Hypochlorite was used as the control treatment. After that, the Cysts with 2 g/l density at 27 ºC for 24 hours were hatched. The results showed that the most hatching rate (70 percent) was related to ALCOH3 and the least rate (21 percent) was related to Na2Co4 revealed a significant difference between them (p<0/05). According to the results, It is suggested to be used of Aluminum hydroxide in order to increase the efficiency of Artemia cysts (A. franciscana) hatching.
