Comparative study of growth and survival rate in Artemia uramiana fed by Chlorella sp. and Chaetocerus sp.

Abstract

Artemia uramiana hatched in the laboratory condition were reared in small glass aquariums for 20 days in 4 replications and fed with Chaetocerus sp. and marine Chlorella sp. as treatments. Culture conditions such as temperature, salinity and pH were kept the same for all treatments and replicates. A one-way analysis of variance, showed a significant difference in the mean growth rate of the Artemia treated with different food items (P<0.05), but no significant differences was found in the Artemia survival rate (P=0.4321). The average survival rate and the mean length of Artemia fed on Chaetocerus sp. were 95%, 97%, 93%, 94% and 7.77, 7.76, 8.01, 7.87; for the four replications. For the Artemia fed on Chlorella sp. the values were 82%, 80%, 77%, 85% and 7.06, 7.66, 7.53, 6.83 respectively.
