COMMON NAME:

Blacktail, Cape White Seabream (Afr: Dassie, Kolstert - Deutsch: Große Geißbrasse)

LATIN NAME:

Diplodus Sargus Capensis

DESCRIPTION:

The head and body of the blacktail is usually silvery and there is a black blotch on top or on the side of the peduncle below the rear end of the dorsal fin. Large adults are almost uniformly black while juveniles have 8-10 faint black bars dorsally on the body. Adults also show dark bars at night. Blacktail from Namibia are generally bigger than South Africa fish and often have yellowish flecks on the body. Blacktails north of Cape Vidal and Sodwana Bay are smaller (rarely over 30cm fork length) and the black blotch is mostly on the side of the peduncle.

DISTRIBUTION:

Southeast Atlantic and Western Indian Ocean: Angola to Mozambique and southern Madagascar, possibly reaching Mauritius.

HABITAT:

Tropical - 35°S - reef-associated, brackish, marine. Blacktail is normally found inshore in shallow rocky areas and sandy substrate with high turbulence. Also living freely in estuaries. Juveniles in shallow reefs, estuary mouths and intertidal pools, sandy beach surf zone.

REPRODUCTION:

Like some other members of the Sparidae family, dassies change sex periodically. Spawning takes place throughout the year, but more often in winter and spring.

SEASONAL MOVEMENT:

?

FEEDING / DIET:

Omnivorous on seaweeds, sponges and bivalves. Also feeds on crustaceans, worms, mollusks, and fish. It is a persistent feeder. The feeding habits and alimentary canal of the blacktail changes with age, from a short gutted carnivore to an omnivorous adult with a longer intestine better suited to digesting plant material. Juveniles of 2-3cm standard length eat copepods, polychaete worms, amphipods, insect larvae, etc. Juveniles over 5cm feed on algae, echinoids anthozoans, sponges, bivalves and tunicates. The juveniles feed on the vertical surfaces of gullies. At night blacktail hover in midwater or rest on the bottom.
