The data on Careproctus furcellus and C. rastrinus (Liparidae) from the Olyutorskii Gulf of the Bering Sea: Size composition, indices of organs, and diet

Traits of biology of Careproctus furcellus and C. rastrinus are reviewed on the basis of the material of bottom trawlings made in the Olyutorskii Gulf between 59°40′ and 60°05′N and 166°29′ and 168°32′ E at depths from 240 to 580 m on June 10-August 1, 1999. These species spawn in the Olyutorskii Gulf in the second half of June-the beginning of July. Careproctus furcellus attains 50% maturation at length 32 cm and C. rastrinus attains the same at 32 cm. The mean individual absolute fecundity of C. furcellus is 1129 eggs, diameter of oocytes 3.46 mm, and weight 29.2 mg. The diet of C. furcellus basically consists of Gammaridae, Pandalidae, and that of C. rastrinus basically consists of Gammaridae and, to a lesser extent, Pahuridae. © 2010 Pleiades Publishing, Ltd.
