文摘
Data of long-term studies (1997–2013) on biology of Hadropareia middendorffii from different areas of Tauysk Bay, the Sea of Okhotsk are generalized. This species is widespread over the entire northern coast of the Sea of Okhotsk, and it prefers sandy-pebbly grounds. Maximum sizes and age comprise 267 mm, 73 g, and 7+; in catches, individuals with a length of 9.1–12.0 cm, weight 0.1–10.0 g, at an age of 1+ to 3+ dominate. In general size–age characteristics of females and males as a whole are rather similar, and sex ratio is nearly equal. Hadropareia middendorffii spawns from the second half of June to the first 10-day period of August; its fecundity varies within 67–219 eggs.
