Walleye pollock

The Walleye pollock is the most common and numerous species occurring in the northern part of the Pacific Ocean. The species is commonly found in Kamchatka waters near the eastern Pacific coast, Sea of Okhotsk coast, and western coast of the Bering Sea. This species is quite big in size, with maximum length of 93 cm and weight – up to 5 kg. The maximum age of life is 16 years. Specimens at the age of more than 8 years are quite rare. A Walleye pollock is a fast growing fish, the biggest length growth is observed in early pre-pubescence years.
The walleye pollock is an autumn-winter-spring run fish, the spawning period beginning later in the northern areas of the habitat. The species is characterized by seasonal migration depending on certain lifecycle periods. During the pre-spawning period, pubescent walleye pollocks concentrate near spawning regions at the depth of 200-300 meters. As the genital products develop, the species moves towards the shelf; by the end of the spawning period the reproducing specimens go up to the depth of 40-50 meters. After spawning, walleye pollock gradually leaves the spawning areas and disseminates both at the shelf and shallow depths and above oceanic depths up to 2-3 thousand meters. Nutrition chain: the walleye pollock is mainly a plankton eating fish.
