Moina sp. is commonly used as live feed source for larviculture and ornamental fish<br />

industry. This research attempted to determine total bacterial count (TBC) and<br />

proximate compositions of Moina sp. which cryopreserved with dimethyl sulfoxide<br />

(DMSO), ethylene glycol and glycerol at concentration of 5, 10 and 20%. Live<br />

preserved samples (LPS) had the lowest TBC among all treatments. In addition, TBC<br />

of DMSO was found the lowest among other cryopreserved treatments. Besides, Moina<br />

sp. with glycerol had the lowest (p0.05)<br />

to other samples. This similar result was found in protein content. Lastly, lipid content<br />

in glycerol was significantly (p
