Introduction

The Milkfish is a schooling species that has a small toothless mouth and a large deeply-forked caudal fin. It occurs in freshwater, estuarine, and inshore tropical and subtropical waters.

Identification

The Milkfish is a schooling species that has a small toothless mouth and a large deeply-forked caudal fin. The eyes are covered with a thick layer of gelatinous tissue. The body is silvery blue-green above, silvery on sides and white below.

Habitat

It occurs in freshwater, estuarine, and inshore waters. On the Great Barrier Reef, adult Milkfish live inshore, but in summer, they migrate across the Great Barrier Reef Lagoon, and spawn just outside the ribbon reefs in the Coral Sea. The larvae then move back across the lagoon and recruit to shallow, inshore waters (Leis and Reader, 1991).

Distribution

The species occurs in tropical and subtropical waters of the Indian Ocean and Western to Central Pacific. In Australia it is known from the south-west coast of Western Australia, around the tropical north of the country and south on the east coast to at least Jervis Bay, but possibly to Victoria.
