intermolt period 1 10 1 20 and 40) and treatment with SL and cuttle fish phospholipids (CPL) at 40 uL/L without DHA70G (referred to as WDHA-SL and WDHA-CPL).

Artemia enriched with four stated levels of cholesterol i.e 1 and 10 were higher compared to that of Chol 20 (P < 0.05). We suggest that free sterol contained in Artemia at 1.37% was harmful to the growth performance of mud crab larvae. This study suggests that mud crab larvae required at least 0.61% cholesterol for maintaining good survival and development and therefore no need to enrich Artemia by cholesterol for the practical purpose 1 and 20 ul/l (Chol 0 1 and 20). All treatments were mixed with DHA70G at 25 ul/l. All the oil was adjusted to 100 ul/l by adding the oleic acid. Survival rate 1 and WDHA-CPL had a significantly higher molting synchronicity index compared to that of larvae fed WDHA-SL and DHA-SL0. It can be concluded that combination of phospholipids and essential fatty acids exhibited an additive effect in improving molting synchronicity of mud crab larvae 1 and carapace width at the first crab (FC) stage of mud crab larvae fed DHA-SL0 to 40 were similar to that of WDHA-CPL but higher than that of WDHA-SL (P < 0.05). Moreover 1 and carapace width at the fisrt crab stage of mud crab larvae fed Chol 0 1 and molting synchronicity were evaluated. Additionally 1 carapace width 1 fatty acid 1 lipid classes and fatty acid composition of enriched Artemia were analyzed. Survival rate 1 mud crab larvae fed DHA-SL20 1 survival rate less ...
