Cod-like fish

Cod-like fishes belong to the Gadidae family. This includes the Atlantic and Pacific cod, pouting, haddock, whiting, European pollock, Alaska pollock and saithe. They live near the seabed in coastal waters and in deeper waters. During the day, they aggregate in schools. At night, they separate to forage independently. Gadidae are omnivorous fish that feed on worms, molluscs, bivalves, crustaceans and small fish. They migrate over large distances to spawn and to hunt on large schools of herring and smelt.

 

 

Blue grenadier

The blue grenadier, blue hake, hoki or whiptail can be found in waters surrounding New Zealand and Australia. This species belongs to the hake family. The blue grenadier can reach up to 120 cm in length and is characterized by a long tail with a pointy end. This species lives at depths between 10 and  1000 m and mainly feeds on crustaceans, squid and other fish.

Explanation assessment

Blue grenadier, or Hoki, has been available MSCMSC:
Marine Stewardship Council, an independent, international non-profit organization that has developed an eco-label that guarantees well-managed, sustainable fisheries. Fish products that meet the criteria of the eco-label can be identified by the blue MSC logo.
-certified since 2015, with fisheries in Australia and New Zealand. Hoki is one of Australia’s most commercially important species. Under MSC certification, hoki populations are well managed and efforts are made to reduce interactions between fisheries and seals. MSC-certified hoki are caught using bottomBottom trawls:
A fishing technique in which cone-shaped nets terminating in a codend are dragged through the water column or along the bottom.
