Quantitative indices of herring infestation in Sakhalin waters reveal a high infection rate of fish in the basin of the Sea of Okhotsk, off the east coast of the island. Moreover, in certain years almost 100% of herring were infested. The so-called local populations as well as widely migrating Sakhalin Hokkaido herring are confined to the area of this waterbody. In the basin of the Sea of Japan, off the west coast of Sakhalin, the indicator values of herring infestation are much lower. The local population as well as widely migrating herring of Sakhalin Hokkaido population are confined to this marine area. The causality analysis of herring infestation in these areas allows to confirm our earlier conclusions about population structure of herring inhabiting the waters around Sakhalin Island.

A new species of marine fish leeches is described and compared with its congeners. Oceanobdella sakhalinica possesses a unique combination of characters: the anterior sucker is small; one of posterior transverse bands on the urosome is very dark; a wedge-shaped patch is located on the posterior sucker; posterior crop caeca are separate for their entire length; accessory glands on the atrium are lacking; five pairs of testisacs are present; the copulatory area and the conductive tissue are lacking. Hosts include a sculpin Myoxocephalus sp. and the blackline prickleback Acantholumpenus mackayi. The leeches were collected in Aniva Bay, southern Sakhalin.
