Distribution

provided by FAO species catalogs
There are two disjunct populations, one of which (M. a. australis) is found from about 38°S to nearly 62°S around the Falkland/Malvinas Islands and Argentine Patagonia in the western South Atlantic; also off South Georgia, South Shetland and South Orkney Islands and in the southeastern Pacific, off Chile; the other population (M. a. pallidus) lives on the various banks and rises around the South Island of New Zealand.

Brief Summary

provided by FAO species catalogs
Benthopelagic to pelagicat depths of about 70 to 800 m, invading the shelf 60° waters during summer and concentrating over the continental slope in winter. The New Zealand population is most abundant at 500 m (range: 180 to 800 m), the Argentine fishes at about 200 m (range: 70 to 620 m).In warm summers, the population of the Falkland/Malvinas current (on the Patagonian shelves of Argentina and southern Chile) migrates southward to S. Georgia, S. Shetland Islands, Elephant Island and the northern part of the Antarctic Peninsula.Up to 30 cm length, all fish are males, at 50 cm females and males are in the same proportion, and larger than 50 cm 90% are females. Spawning occurs from June to July in New Zealand and spring to early summer in Patagonia and the Falkland/Malvinas Islands. Growth rate differs by sex with females larger than males: 1 year = 13 cm; 2 years = 22 cm; 3 years = 29 cm; 10 years = 50 cm females and 47 cm males.The young feed on euphausids and amphipods and occasionally on copepods, cephalopods, octopods and small fish.

Benefits

provided by FAO species catalogs
Catches of Micromesistius australis are reported from areas 41 (128,727 t in 1995), 81 (32,322 t) and 87 (20,917 t). In area 41 most of the catches are taken by Argentina, the rest by distant fishing fleets. Caught with mid-water trawl and bottom trawl mostly on the Patagonian/Fuegan shelf, off Argentina, and off the southern shelf of New Zealand. Also very abundant around Elephant and S. Orkney Islands. The total catch reported for this species to FAO for 1999 was 167 282 t. The countries with the largest catches were Argentina (55 097 t) and New Zealand (39 012 t). Utilized mainly in frozen blocks and as fish meal.

Biology

provided by Fishbase
Invades shelf waters during summer and concentrating over the continental slope in winter. Forms schools (Ref. 9072). The young feed on euphausiids and amphipods and occasionally on copepods, cephalopods and small fish. Utilized in frozen blocks and as fishmeal. In Japan used as suerii (minced meat) for karaoke (fish cake) (Ref. 27363). Can be fried, microwaved and baked (Ref. 9988).

Southern blue whiting

provided by wikipedia EN

The southern blue whiting (Micromesistius australis) is a codfish of the genus Micromesistius, found in the southern oceans with temperatures between 3 and 7 °C, at depths of 50 to 900 m. Its length is commonly between 30 and 60 cm, with a maximum length of 90 cm.[1] Maximum weight is at least 1350 g.[2]

Southern blue whiting fillet

A related species, the blue whiting, Micromesistius poutassou, occurs in the Northern Hemisphere.

In Canada, according to Canadian Food Inspection Agency regulations and the list of acceptable fish species names, "Micromesistius australis" (or southern blue whiting) can also be referred to as blue cod.[3][4] This well-known species is part of the family Gadidae and is a very versatile fish. It is most commonly filleted and served breaded or battered, but it is also well-suited to pan frying, oven baking and steaming. It has flaky white fillets and mild flavor with broad appeal to children and adults alike.

The two disjunct populations are:[1]

Most of the southern blue whiting catch comes from New Zealand's Bounty Platform and Campbell Island Rise given the large numbers there. They are harvested mainly by mid-water and semi-pelagic trawl.[6]

New Zealand southern blue whiting were the first blue whiting fisheries in the world to gain Marine Stewardship Council certification, the ‘gold standard’ for sustainable fisheries performance.[6]

The two disjunct populations are:

M. a. australis occurs around the Falkland Islands and Argentine Patagonia in the southwest Atlantic, off Chile in the southeast Pacific, and off South Georgia, South Shetland and South Orkney Islands. M. a. pallidus occurs around the South Island of New Zealand. Some evidence indicates southern blue whiting in this area may actually comprise multiple stocks.

Most of the southern blue whiting catch comes from New Zealand's Bounty Platform and Campbell Island Rise given the large numbers there. They are harvested mainly by mid-water and semi-pelagic trawl.

New Zealand southern blue whiting were the first blue whiting fisheries in the world to gain Marine Stewardship Council certification, the ‘gold standard’ for sustainable fisheries performance.
