Bering wolffish Anarhichas orientalis (Anarhichadidae) off the coasts of Sakhalin and the Kuril Islands

Abstract

According to long term materials of bottom and pelagic trawl surveys, the distribu tion and some features of biology of pelagic juveniles and adult individuals of Bering wolffish Anarhichas ori entalis off the coasts of Sakhalin and the Kuril Islands are considered. Maximum sizes and age of wolffish are 113 cm, 10.8 kg, and 14 years. It is shown that the seasonal dynamics of distribution and numbers of pelagic juveniles off the Sea of Okhotsk coasts of southern Sakhalin is closely related to the regime of water warming. It is suggested that considerable variability of size-weight indices of juveniles at the beginning of summer is determined by extension of the dates of spawning of wolffish off the coasts of Sakhalin and the presence of fish from other areas of reproduction. Data on feeding of different size groups of wolffish fingerlings are pre sented.

Resilience and the population history of the Kuril Islands, Northwest Pacific: A study in complex human ecodynamics

“…The Kuril Islands have been occupied periodically since at least the mid-Holocene—some islands earlier—and archaeologists have studied the culture history of the region for over 100 years (Fitzhugh et al, 2002; Kuzmin et al, 1998, 2012; Ohyi, 1975; Shubin, 1977, 1991; Stashenko and Gladyshev, 1977; Torii, 1919; Vasilevsky and Shubina, 2006; Yamada, 1999; Yamaura, 1998; Yanshina et al, 2009). Aside from the most recent Russian and Japanese settlement of the Kuril Islands, all cultural occupations were based on hunting and gathering of marine mammals, fish, birds, eggs and to a lesser degree shellfish (Fitzhugh et al, 2004).…”
