Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Adults are usually demersal on the continental shelf and slope, occasionally occurring at the surface; subadults in surface waters, sometimes entering bays, while juveniles occur offshore (Ref. 9563). Reported from depths of 27 m (Ref. 58489) to 600 m (Ref. 9563). They form feeding and spawning aggregations. Spotted warehou are schooling species, usually aggregating close to the sea bed (Ref. 26498) although there is some evidence that they move into the middle water column at night (Ref. 30459). During spring-summer in New Zealand, adult and juvenile fish migrate to feed along the continental slope off the east and southeast coast of the South Island (Ref. 9072). Adults mainly eat planktonic tunicates (Ref. 6390).
In New Zealand, spotted warehou are thought to undertake a southerly migration following spawning on the Chatham Rise in spring (Ref. 26998).
