Abstract

Three species of jellyfish (Rhizostorna sp.l, Rhizostorna sp.2 and Chiropsalmus quadrigatus) were sampled from Sepangar Bay and Tanjung Am beach, Sabah for analysis of biochemical properties which are protein content, lipid content, fatty acid content, moisture content and ash content. These species were examined to distinguish whether significant differences of biochemical properties exist between comparisons of species. The results of analyses were also used to determine specific biochemical characteristic of jellyfish that qualifies them as preferred food for sea turtles. There was a significant difference in protein content between Rhizostoma sp.l and Rhizostoma sp.2, whereas no significant difference was found in lipid content between all analysed species of jellyfish. The moisture contents between Rhizostorna sp.1 and Rhizostoma sp.2 showed a significant difference while the ash content analysis showed significant differences between Rhizostoma sp.1 and C. quadrigatus. The fatty acid analysis showed that the profile of Rhizostoma sp.l and Rhizostoma sp.2 were very similar in the Retention Time and fatty acid fractions whereas profile of C. quadrigatus showed vast differences with Rhizostoma sp.l and Rhizostoma sp.2 with more poly-unsaturated fatty acid fractions. The results show that Rhizostorna sp.1 and Rhizostoma sp.2 are jellyfish of different species but in same genus. The differences in biochemical properties between Rhizostoma sp.l and Rhizostorna sp.2 with C. quadrigatus especially fatty acid content might make C. quadrigatus as preferred food for sea turtles.
