GENOMIC VARIATION AND NUTRITIONAL COMPOSITION IN SARDINELLA LEMURU: A FOCUS ON OMEGA-3 CONTENT

Sardinella lemuru or Sardine is a marine fish that contains a high amount of omega-3 that is abundant in Lombok Strait. Therefore, the genetic variation of the S. Lemuru and its omega-3 production has not been widely studied yet. Furthermore, we have analyzed the correlation between genetic variation and omega-3 content in S. lemuru in Lombok strait. The variations of the S. lemuru were analyzed by using morphology and RAPD method. The result suggested that the S. lemuru in Lombok Strait has three variants that were associated with omega-3 production. Although differences of omega-3 content in marine fish could be caused by various factors, but the differences in the omega-3 content of Sardine in Lombok strait can be assumed due to genetic variations. This study also has discovered a molecular marker based on RAPD method by using primer 5'-AAGAGCCCG to identify Sardine that has high production of omega-3 cheaply, which is very beneficial for managing the conservation of Lombok Strait
