The difference between dogfish and silver cod is as follows:
Difference in origin
Dogfish are mainly found in the southeastern Pacific Ocean and the southwestern Atlantic Ocean. It ranges from off the southern coast of Chile to Patagonia and the Falkland Islands, Macquarie Island in the southwestern Pacific, South Georgia in the Southern Ocean, and is also found under the Antarctic Islands and near seamounts in the Indian Ocean.
Silver cod are found on both sides of the North Atlantic, including the Bering Sea coast of the Kamchatka Peninsula, Alaska, California and other waters. It is a cold-water demersal fish that generally inhabits the near-bottom layer. The body of the cod contains a large amount of fat, and the meat is white and tender when eaten.
Difference in Genus
The canine toothfish is a member of the class Sphenophora, order Perciformes, family Antarctica, and the genus Canine Antarctica. There are mainly 2 economic species, the small-scaled canine tooth Antarctic fish and the Mo's canine tooth Antarctic fish. Silver cod, also known as the naked cover fish, is a black jack family, naked cover fish genus fish, and the appearance of the cod is similar, is one of the people often eat fish, widely distributed in the world's oceans.
Difference in Appearance
The dogfish is a large and medium-sized benthic freshwater fish with stunted growth, with a very increased and slightly laterally flattened, cylindrical body. The head is pointed, the mouth is medium to large, and the upper jaw is slightly better than the lower jaw. The teeth are small, in bands, and the upper and lower jaws, hoe bones, and palatine bones are toothed. Head and body covered with soft rounded scales, caudal fin y forked. Body dorsum dark grayish blue or greenish dark gray; body venter dark gray or light colored.
The body of the silver hake is rather extended and slightly laterally flattened, cylindrical. The head is pointed, the mouth is large, and the upper jaw is slightly longer than the lower jaw. The teeth are small, in bands, and the upper and lower jaws, hoe bones, and palatine bones are toothed. Head and body covered with weak rounded scales. Dorsal fin separated, caudal fin y forked. The body is dark blue-gray or green-gray dorsally, gray or pale ventrally, and all fins have a black outer edge except for the first dorsal fin.
Difference in habits
The canine toothfish generally inhabits near the bottom, a cold-water benthic freshwater fish, the fish roe is oceanic floating eggs, and after oviposition of the young fish along with the development of the human body, slowly from the shallow waters of the sea areas continue to transfer to the seabed. Omnivorous, most feed on shrimp, large squid, spiders or fish.
Silver cod is a deep-sea fish that lives in cold waters. Its eggs are oceanic floating eggs, and after hatching, the juveniles gradually migrate from shallow waters to the deep sea as they grow older. They are omnivorous, mostly feeding on shrimp, worms or small fish.
Difference in nutritional value
The flesh of the dogfish is tender, known for its few bones and tender white flesh, and its nutritional value is also very high, and it is sold at about the same price as silver cod, and in some cases is more expensive than silver cod. But in comparison, silver cod has a higher nutritional value, the fish meat is rich in fat, protein and a variety of vitamins.
Introduction of the dogfish
The Antarctic dogfish is a large, slow-growing demersal fish, with a length of up to 2.2 meters and a weight of more than 100 kilograms, and can survive for 50 years. It takes about 10-12 years for the species to reach maturity, and the adult fish is about 70-80 centimeters long. It is mainly found in southern Chile, Argentina and the sub-Antarctic archipelagic waters under the jurisdiction of Australia, France, New Zealand, South Africa and the United Kingdom, where it survives to a depth of 2,500 meters.
The Antarctic dogfish is known for its low bone count and white, crystal clear flesh. The fishery dates back to the late 1980s and early 1990s, when the species was first caught by the U.S. and Norwegian longline fisheries off the coasts of Argentina and the Falkland Islands in the southwest Atlantic. In view of the Antarctic dogfish prices continue to rise to become a first-class food fish, known as "white gold", profit is considerable, resulting in many countries have invested in the fishery, the catch in 1995 reached 44,000 tons of the peak.
