Abstract

The occurrence of Acanthocybium solandri in the hooks and line catches off Lawsons Bay was noticed in1988 and 1990. The specimen was infested with the parasitic copepod of the genus Lernaeenicus, almost similar to L. seeri. The occurrence of A. solandri off the north coast of Andhra as reported now confines to the period October - March. This is the period when a strong surface current from the Malasian region enters the south-east corner of Bay of Bengal,bringing the equatorial Indo-Pacific waters.Wahoo' probably enters the Bay of Bengal along with this current and moves along with the prevaling currents on the east coast of India during October – March.
