Narrow Barred Spanish Mackerel ( Scomberomorus commerson ) Confirmed with Leucism from East Coast of India

A single abnormally pigmented leucistic fish was collected from commercial fish catch from off Bay of Bengal, east coast of India. Using morphometric and DNA barcoding analysis, the fish species was identified as narrow barred Spanish mackerel (Scomberomorus commerson). The standard length of the fish was 130 cm and weight was 1600 g. Mitochondrial COI gene sequence search of the leucistic fish specimen showed more similarity towards the species Scomberomorus commerson in the scombroid fish group. This is the first report confirm the species narrow barred Spanish mackerel with leucism from the region and is probably caused by random genetic alterations.
