North Atlantic, Argentina (Argentina silus)


Widely distributed in temperate waters of the American and European shores of the Atlantic Ocean from 40° . sh. to 54°40'. sh. to the west and from Ireland and the Skagerrak to the North of Norway and south-western Barents Sea in the east. This fish has a very slow growth and achieves a length of about 60 cm up to 25 years. In the age of 9-12 years, Argentina becomes sexually mature. It reproduces in the spring, from March to May, and spawns from 3500 to 7500 a fairly large eggs. The developing egg has a red oil drop, it floats at depths of 300-400 m. Argentina adults have gregarious way of life in the bottom layers of water at a depth of 150-600 m and more. Their food predominantlyis a variety of invertebrates (small shrimp, squid, ctenophores), and some times small fish. Once in the stomach of Argentina had been discovered deep-sea fish Cyclothone (family Gonostomidae). Catches of this delicious fish are small. The North Atlantic silverfish is an example of a specie with low reproductive capacity. The reason is its slow growth, late sexual maturity and low fecundity.
