Description

The luderick or blackfish is a schooling fish of the family Kyphosidae from temperate coastal waters of southern Australia and New Zealand. The species grows to about 71 cm and has a deep, dark body with narrow vertical bars. It inhabits estuaries, rocky reefs and coastal waters and flourishes especially in seagrass areas. Luderick are moderately sedentary schooling fish and decided herbivores feeding mainly on seagrass and filamentous algae; the species name (tricuspidata) refers to its three-cusped incisor teeth. The luderick is a popular angling fish caught with weed or green bait, and a valued food fish.
