The wildlife that can be encountered in the vicinity of the Laboratory
It is located on the Pacific coast of eastern Hokkaido, 50 km east of Kushiro City, on the bedrock below the cliffs of Cape Aikappu on the eastern shore of Akkeshi Bay. The seafloor in front of the site is bedrock and sand and gravel. Lake Akkeshi, which is connected to the bay, was shallow, with eelgrass and large and small oyster reefs, but the oyster reefs have now disappeared.In the bay, there are fisheries for shishamo, hagfish, komai, hokki, flatfish, and kelp, and in the lake for shiraoi, hokkai shrimp, magaki, and clams. Offshore, Daikoku Island has been designated a natural monument as a breeding ground for seabirds, with flocks of white-rumped petrels laying eggs in the island, and nesting Greater White-fronted Gulls, Cormorants, Sea Urchins, and Etopilicas, as well as harbor seals and Gomafu seals.
The front of the laboratory is a protected restricted marine area. In addition to hydrozoans, sea anemones, and gorgonians, there are also giant mussels, the Okhotsk flatworm, the Okhotsk flatworm, the Hokkai shrimp, and the Okhotsk hermit crab, and it is relatively easy to collect the Hanasaki crab, chestnut crab, and compound boa.
In the premises, the Reverdin's jay, Ezo red-bellied woodpecker, white-breasted nuthatch, and Japanese nightingale can commonly be seen, and foxes, Ezo hares, Ezo squirrels, chipmunks, and Ezo sika deer can also be encountered. The Cape Aikappu coastline is a special research reserve, off-limits to non-researchers so as not to interfere with field experiments.
The sea water temperature rarely exceeds 20 degrees Celsius due to the cold currents, and there are many foggy days in June and July. The lake is frozen over from January, and the sea surface in front of the experiment station is covered with lotus-shaped ice.There is little snowfall, and snow removal is not required on many days. The highest and lowest average monthly temperatures at 10:00 a.m. are in August (18.3°C) and January and February (-3.3°C), while the average sea water temperature is in August (17.6°C) and February (-0.1°C) (1992-95).
