Proximate composition and Fatty acid analysis of selected commercial fishes in Sarawak

Consumers believed that the nutritional content of many kinds of fish is identical; nevertheless, it differs by species. This study was conducted to compare and analyse the fatty acid content and proximate composition of three commercially fishes in Sarawak, namely Tenualosa toli (Terubuk), Channa striatus (Haruan) and Xenopterus naritus (Buntal Kuning). In general, the moisture content varied between 6 and 77%, the ash content varied between 1 and 5%, and the protein content varied between 20 and 87%. In this study, the chemometric analysis showed the fatty acid content of eicosapentaenoic acid and arachidonic acid Tenualosa toli and Xenopterus naritus were (2.70%, 0.73 %) and (0.16 %, 0.61 %) respectively while the content of arachidonic acid in Channa striatus was 1.47%. The dominant saturated fatty acid in this study is palmitic acid with a percentage of 41.10%
