Mitochondrial DNA diversity of wild and hatchery reared strains of Indian Lates calcarifer (Bloch)

Lates calcarifer, locally known as seabass in Asia and barramundi in Australia, is a large, euryhaline member of the family Centropomidae that is widely distributed in the Indo-West Pacific region. Its hardy nature, high tolerance to wide range physiological condition and high commercial value has m...
