Black Rabbitfish, Siganus fuscescens (Houttuyn 1782)

More Info


Distribution

Busselton, Western Australia, around the tropical north to Nadgee, southern New South Wales; also the Lord Howe Province in the Tasman Sea. Elsewhere, the species is widespread in the tropical, east-Indo-west Pacific. 
Inhabits algal and seagrass flats and shallow lagoons, coastal reefs and estuaries. Forms aggregations in clear coastal waters feeding on filamentous algae, leafy algae and seagrass leaves.

Features

Dorsal fin XIII, 10; Anal fin VII, 9; Pectoral fin 15-18; Vertebrae 13.  Slender, pungent, venomous spines. Preopercular angle 89°-95°. Lower half to 2/3 of cheeks commonly covered with weak, scattered scales. Midline of thorax between pelvic ridges.

Feeding

Adults consume brown and green algae, while juveniles prefer filamentous algae and seagrass leaves.

Biology

Prespawning aggregations shoal on inner reef flats, and spawning occurs on the 4th or 5th day of the new moon near the edge of the reef. Females release about 300,000 eggs/female at a single spawning. Eggs and larvae are pelagic.

Fisheries

Fished commercially throughout its range, and commercially cultured in Japan.

Similar Species

The similar Siganus argenteus has a deeply forked tail, and differs in coloration.

Etymology

The specific name is from the Latin fuscescens (= become dark, turning dark), presumably in reference to the coloration of this species.
