Description Asian seabass or barramundi (Lates calcarifer) is an important food fish with commercial
value and a wide geographic distribution. Though some reports based on molecular and/or
morphological data exist, a comprehensive effort to establish species identity across its
range is lacking. In order to address this issue and especially to ascertain whether the
wide-spread distribution has resulted in bifurcation of the species, we collected Asian
seabass samples from various locations representing the Western and Eastern Coastline
of India, Andaman and Nicobar Islands, Bangladesh and Australia. Samples from Malaysia,
Indonesia, Thailand and Singapore were collected as part of a previous study. DNA
sequence variations, including cytochrome c oxidase subunit 1 (COI), 16S rDNA and the
highly variable D-loop (or control region), were examined to establish species delineation.
Data from all the sequences analyzed concordantly point to the existence of at least two
distinct species—one representing the Indian subcontinent plus Myanmar, and a second,
representing Southeast Asia (Singapore, Malaysia, Thailand and Indonesia) plus Northern
Australia. These data are useful for conservation ecology, aquaculture management,
for establishing the extent of genetic diversity in the Asian seabass and implementing
selective breeding programs for members of this species complex.
