Cobia, Rachycentron canadum, is a large marine finfish species distributed
widely in subtropical and tropical oceans and seasonally in
temperate waters (Briggs, 1960). In recent years, the potential for
cobia aquaculture has been recognized because of its good meat quality,
rapid growth rate and good disease resistance. In Southern China, the
artificial culture of cobia has become popular and rendered aquaculture
investment and development an excellent prospect. However, unlike
established mari-culture fish species such as salmon, sea bass and sea
bream, cobia is a recent candidate for use in aquaculture, and the knowledge
on cobia is still poor though more research has been carried out in
recent years
