To treat the fish we love
But you know what?
There is such a fish that seems to have become
An indispensable dish on our dinner table
They are known in Northern Europe as "dietitians at the table"
However, in 1996 it was recognized by the International Union for Conservation of Nature (IUCN)
Listed on the Red List of Threatened Species ver 2.3 Vulnerable Species (VU)

Cod (local names: big head blue, big mouth fish, big head fish, ming tai fish, water mouth, broad mouth fish, big head fish, stone intestine fish). Pure cod refers to cod fish, divided into Atlantic cod (Gadus morhua), Greenland cod (Gadus ogac) and Pacific cod. Cod is one of the largest annual fish catches in the world and is of great food and economic value.
They are found in the North Pacific Ocean, where they generally inhabit the near-bottom layer and are carried from nearshore to the deep sea. It is native to the cold waters of the North Atlantic ocean from northern Europe to Canada and the eastern United States. The world's main producers of cod are Canada, Iceland, Norway and Russia, and Japan is mainly produced in Hokkaido. China is mainly distributed in the Bohai Sea, the Yellow Sea and the northern part of the East China Sea, and there are major fishing grounds in the northern Yellow Sea, the east-southeast of Gaojiao in Shandong, and the southern and southeastern sea areas of Ocean Island.
It inhabits the cold water area of the Yellow Sea in summer and autumn, and winters back to the coastal mud bottom area with a water depth of 50 to 80 m. Most cod live in the cold sea of 0 °C to 16 °C in the Pacific Ocean and the northern Atlantic Ocean. Cod feeds on other fish and invertebrates, eats more, grows faster, and can grow to 1 meter in about 10 years; it is a gluttonous migratory fish, because of the group life, it is easy to catch, and it has been quite famous since ancient times.
Among them, the Arctic cod is distributed throughout the Arctic region and is a typical cold-water fish, when the temperature exceeds 5 ° C, they are not found. It is a small and medium-sized fish with a maximum body length of up to 36 cm and is one of the important economic fish in the Arctic.
In summer, the Arctic cod mainly lives on the edge of the icy area of the Barents Sea in the Kara Sea, and the juvenile Arctic cod feeds on small phytoplankton and zooplankton, and as it grows, the individual plankton it feeds gradually changes from small to large, and partially preys on small fish. By September of each year, Arctic cod begins to migrate west and south, laying eggs at sub-zero temperatures in winter, and hatching for up to 4 to 5 months due to low water temperatures.
The nutritional value of cod is very high.
They generally inhabit the near bottom (water depth 0-2740 m), are cold-water demersal fish, and are one of the marine economic fish produced on the northern coast. Its flesh is white and tender, the mouth is not greasy, and many countries in the world regard cod as the main edible fish. In Northern Europe, cod is known as the "nutritionist on the table", in addition to fresh food, but also processed into a variety of aquatic foods, in addition to cod liver is large and high oil content, rich in vitamins A and D, is the raw material for extracting cod liver oil.
It is also because of the high edible value and nutritional value of cod that overfishing has caused a sharp decline in the number of Atlantic cod.
From the 1960s to the early 1990s, Atlantic cod populations plummeted by 99.9 percent off Newfoundland, one of the worst "collapses" of marine and even land animals ever created. Although countries have implemented a series of bans since 1993, it is expected to see a recovery in cod stocks.
However, after more than 10 years of limited fishing or even a ban on fishing, cod populations have shown no signs of rebounding, but have remained at historic lows, and their individual size is far less than before, and the growth and reproduction of existing cod is very slow because the largest and fastest-growing cod are almost completely caught.
Canadian scientists have used well-established fishery stocks to predict the future of cod stocks living in Newfoundland. These models take into account the reproduction rate of cod populations – based on the proportion of cod larvae in the population, the growth status of adult individuals, and natural mortality. The final prediction is regrettable: if limited fishing is allowed, cod populations living in the southern part of the bay will become extinct within the next 20 years.
French scientists have also found that rising ocean temperatures caused by global warming are causing a double catastrophe for cod.
Atlantic cod is listed on the IUCN Red List of Threatened Species in 1996 ver 2.3 – Vulnerable Species (VU); the International Council for the Exploration of the Sea (ICES) Safe Bio-Restricted (SBL)!
