Abstract

We report the first record of intersexuality in walleye pollock Theragra chalcogramma (Pallas, 1814) caught in the Bering and Okhotsk seas. Prevalence of intersexuality was low (0.0003–0.0016%). We describe intersex gonads at the macro- and microscopic levels (using histological methods).
