No notable changes occurred in the distribution of Steller sea lions on the eastern coast of the island, however, Steller sea lions decreased in abundance in the southern part of the island in the Funka Bay region.
From the late 1990's to 2000, Steller sea lions were more numerous in the central western coast on the Shakotan Peninsula, but they became less common at the northwestern extremity, along the eastern coast, and the southern coasts from Nemuro Strait to Funka Bay (Ishinazaka (40), Hoshino (41)).
Distribution and movement of walleye pollock larvae Theragra chalcogramma in
Funka Bay and the adjacent waters, Hokkaido.
In Funka Bay, the main spawning ground for this population, pollock spawn from December to March (Kendall and Nakatani, 1992).
The aim of the present study was to examine, by using otolith daily growth ring analysis, regional differences in hatching date, body size, and early growth of juvenile pollock in Funka Bay and the Tohoku area and to elucidate the importance of Tohoku area as a nursery ground for the Japanese Pacific population of pollock.

ABSTRACT Spawning season of Strongylocentrotus intermedius in Hokkaido is classified into the 3 types, Sea of Japan, Funka Bay, Sea of Okhotsk, and Pacific Ocean.
intermedius in Hokkaido, spawning is classified into three types: Sea of Japan type with intensive spawning in autumn, Funka Bay type with spawning in spring and autumn, and Sea of Okhotsk and Pacific Ocean type with spawning from spring to autumn (reviewed by Agatsuma 2001).
