Silver Warehou are common around New Zealand's South Island and on the Chatham Rise at depths between 200 and 800 metres.
The majority of the commercial catch is taken from the Chatham Rise, Canterbury Bight, southeast of Stewart Island and the west coast of the South Island.
Silver Warehou belong to the Centrolophidae family of Raftfishes and Medusafishes.
They are blue-grey above and silver-white below with a dark head. There is a dark blotch above the pectoral fin and blackish spots on the mid belly. Silver Warehou are more slender in shape than Blue or White Warehou.
The flesh is firm and white.
Silver Warehou is managed by the Ministry for Primary Industries using the New Zealand Quota Management System (QMS). Regular stock assessments are conducted to estimate fishery stock size and numbers. Scientific studies are also used. From these, scientists can estimate future stock sizes and catch limits.
They are generally found at depths of 200 and 800 metres on the Chatham Rise, the outer Canterbury Bight, off the west coast of the South island and along the shelf edge south east of Stewart Island
Silver Warehou have firm, white flesh fillets with a high fat content. It is suitable for most cooking methods including baked, fried, poached, grilled, steamed and barbecued.
