EFFECT OF FEED ON CYST HATCHING PERFORMANCE OF FAIRY STRIMP STREPTOCEPHALUS DICHOTOMUS BAIRD (CRUSTACEA:ANOSTRACA)B. Jesi Selvarani
The fairy shrimp Streptocephalus dichotomus has been widely used as food for diverse groups of organisms reared for aquaculture or research purposes. Hatching quality of cysts is of prime importance to aquaculturist and aquariologist. This paper highlights the effect of different feeds on cyst hatching performance of fairy shrimp. Average hatching percentage 86% was recorded that the cysts collected from rice bran fed animals, 74% from cow dung fed animals. Hatching rate was better in the former (24- 48 hours) than the latter (48-72 hours). Cyst hatching efficiency considerably varied between 64% (cow dung fed animals) to 71% (rice bran fed animals) suggesting rice bran found to be a better feed.
