Overview

Comprehensive Description

Biology

Inhabit continental shelf depths mainly between 100 and 200 m (Ref. 1371). Larger individuals feed on fish (anchovies, hake, nototheniids, myctophids and Southern blue whitings), squids and macrozooplankton (euphausiids and amphipods); smaller individuals feed on mysids and amphipods (Ref. 1371). Migrate inshore during spring and summer, and offshore into deep water wintering areas after spawning; also undertake diel vertical migrations (Ref. 1371). Sold fresh and frozen.

Wikipedia

Merluccius hubbsi

The Argentine hake (Merluccius hubbsi) is a merluccid hake of the genus Merluccius, found in the southwestern Atlantic Ocean, along the coast of Argentina.

Very similar to Merluccius merluccius (European hake), it can reach a length of 95 cm, with a weight up to 5 kg. It lives at depths from 100 to 200 m, and feeds on crustaceans, squids and fish (including smaller hakes). It migrates southwards in spring and northwards in autumn.
