Abstract

We present data on the individuals of the barred knifejaw Oplegnathus fasciatus (Temminck and Schlegel, 1844) caught (47°49′28″ N, 142°03′35″ E) in September, 2020, and found under a fishing buoy (46°38′14″ N, 141°39′01″ E) in August, 2023, in the coastal waters off southwestern Sakhalin. The total length (TL) of the captured fish was 10.2–13.8 cm, and their number was at least 1500 individuals. The maximum TL of the largest individual of the four knifejaw found in the open waters under a Korean fishing buoy was about 8 cm. It is supposed that the fishing buoy and the knifejaw drifting along with it were transported to the waters off southwestern Sakhalin by the Tsushima current from Japan’s coastal waters.
