EFFECT OF MICROALGAE ON GROWTH AND FATTY ACID PROFILES OF HARPACTICOID COPEPOD, Tisbe holothuriae
Abstract: Growth of marine
copepods is influenced by feed. The purposes of this trial were to observe both
growth and fatty acid compositions of harpacticoid copepod nauplii, Tisbe
holothuriae by feeding with several microalgal species in laboratory: (A)
Isochrysis tahiti; (B) Nannochloropsis oculata; (C) Rhodomonas sp., and (D)
Tetraselmis chuii. The trial was carried out for 35 days with randomized
complete design and triplicates in each treatment. The results showed that
final copepod nauplii densities were not significantly different (P>0.05) in
all treatments. However, lipid content of copepod nauplii fed with T. chuii was
significantly higher (P<0.05) compared to that of other treatments while
fatty acid profiles of EPA, DHA and DHA/EPA ratios showed both insignificant
and significant differences among treatments.
