GROWTH AND SURVIVAL OF SWIMMING CRAB (Portunuspelagicus) LARVAE FED OMEGA-3 ENRICHED ARTEMIA
Abstract: Highly unsaturated
fatty acid particularly DHA and EPA play important role in survival and growth
of swimming crab larvae. The objective of the present study is to determine
effect of Omega-3 Enriched Artemia on survival and growth of swimming crab
(Portunus pelagicus) larvae from megalopa to crablet-1 stage. Megalopae stage
larvae obtained from natural spawning of a mature berried female kept in
hatchery. The megalopae were stocked at 5 ind/L using 130 L capacity of red
color plastic buckets, filled with 100 L of 30 ppt salinity of sterile treated
seawaters. Live feed using in this experiment was newly hatch artemia enriched with omega-3 rich powder containing
both Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA). Enrichment
concentration examined were 75 mg/L (B), 150 mg/L (C), 225 mg/L (D) and
unenriched artemia as control (A).
