IDENTIFIKASI IKAN SARDIN KOMERSIAL (Dussumieria elopsoides) YANG DIDARATKAN DI PASAR MUARA ANGKE, JAKARTA MENGGUNAKAN PENGAMATAN MORFOLOGI, MORFOMETRIK DAN DNA BARCODING

Abstract

Sardines are an important commodity in import activities. Excessive imports and lack of catch data are feared to reduce fish stocks. To complete the fish catch data required knowledge of body type and size. This study aims to identify and confirm commercial sardines species landed at Muara Angke Market, Jakarta using morphological, morphometric, and DNA barcoding methods targeting the Mitochondrial Cytochrome c oxidase-I (COI) gene. The results of morphological and morphometric analysis showed that the samples are the genus Dussumieria originating from the Dussumieriidae family, the Order Clupeidae, having silver-colored body characteristics with reflections resembling rainbows, slender bodies and rounded stomachs with a maximum length of up to 14.4 cm, then less abdominal fins advance from the midsection. Based on the relationship of body weight length, this fish is negative allometric. Molecular DNA barcoding analysis using COI, obtained by type of Dussumieria elopsoides fish with local name of rainbow sardines, similarity level with Query Cover percentage was 94% and Per percentage. Ident of 91.64%. DNA barcoding analysis has corroborated morphological and morphometric observations by obtaining fish samples identified as Dussumieria elopsoides.
