Morphometric variations among three different populations of Cobia, Rachycentron canadum (Linnaeus 1766) in Peninsular Malaysia

Cobia Rachycentron canadum, is one of the emerging aquaculture species but is usually a non-target resource in fisheries industry and within Malaysia, their landings are among the highest worldwide. Identification of stocks with unique morphological characters is important for effective management a...

description Cobia Rachycentron canadum, is one of the emerging aquaculture species but is usually a non-target resource in fisheries industry and within Malaysia, their landings are among the highest worldwide. Identification of stocks with unique morphological characters is important for effective management and sustainable utilization.
