Oshoro Marine Station is bases 15km southwest of Otaru out of Oshoro Bay. Established in 1908, the facility was first used by the Tohoku Imperial University School of Fisheries, until assimilation into Hokkaido University. It one of the oldest facilities in Japan, 2nd right after Tokyo University Misaki Marine Biological Station established in 1886. Located in the closed-section of Ishikari Bay, Oshoro Bay is exceptionally calm, with water temperatures throughout the course of the year ranging between 5~22 degrees Celsius. The limits on its temperature range are greatly influenced by the Tsushima Current and the Liman Current, which flow through into the bay during the summer-fall and winter-spring seasons, respectfully. Special to the Sea of Japan, there is not much tidal level variation. Even at low tide, the appearance of exposed rock is less common. However, continuing to the conglomerate zone near its mouth, a nesting ground for marine flora and fauna begin to emerge. The waters within the bay, placid even in the midst of strong winds, have been found to be not only suitable for the collection of invertebrate, fish, and marine algae samples; but also meeting the desired conditions for feeding experimentation, seawater surveys, and also plankton sample collection.

Although this laboratory has a reputation to be unstaffed at times, it is maintained and readily available for use. As many students and researchers from Hakodate as well as Sapporo campus often drop by, the facility is thought of as a place for active research. The facility is also often used by independent researchers. To date, this lab has generously been the host to a myriad of research.

This station was built in 1927 by the Lake Toya Fishery Association as a red salmon hatchery. In 1936, it was donated to Hakodate Fisheries High School. Since 2001, it has been used by the Northern Biosphere Field Science Center and is currently referred to as the Toya Inland Water Station. Lake Toya is used for irrigation as well as drinking water. Its waters, considered very important, have been made public and put into environmental protection. The lake is home to many species of aquatic life such as masu salmon, whitespotted char, rainbow trout, ezogei, carp, crucian carp, amur goby, Japanese mitten crab, and lake prawn.

Every year, observation of plankton and dissection of salmon species are carried out by 1st and 3rd year students belonging to Hokkaido University School of Fisheries Department of Marine Bioproductive Science. As two of the institutions big research projects we are:

(1) investigating the lake water environmental conservation along with fish species resource management

(2) researching the possibility of introducing the inhabitants into Hokkaido's salmon resource pool.

Nanae Freshwater Laboratory is situated in the heart of Nanae, the town neighboring the north side of Hakodate, right off of National Highway-5. By vehicle it is roughly 20 minutes from the School of Fisheries on Hakodate campus and 15 minutes from Onuma Park. Water is supplied to the facility by utilizing both the Kunebetsu-Narukawa drainage and a well supplying as much as 1 tonne of water per minute. The facility is home to many common as well as uncommon fish species: such as the Carp; Sturgeons; and 14 different kinds of Masu Salmon taken from 25 distinct genealogical families. In entirety, the fish kept can be seen as precious genetic material. Among the rarest of breeds are the Non-spotted Sakura Salmon and the Albino Ito that are kept in captivity under selective breeding. The facility consists of a main research laboratory, a holding facility, and a fish breading practice lab. In addition, there are 13 concrete based artificial ponds and more than 80 water tanks where wish are kept.

In the field of domestic animal production, the application of cloning technology is actively researched. In our lab, we are wish to research ways to apply the same technology in the field of fisheries. In order to make this happen, we need to push forward research employing techniques used in the field of developmental bioengineering to better understand fish cell differentiation mechanisms. Our goal is to use our findings to help methods to farm the Ito (Hucho Perri), an endangered species of fish recognized by the Ministry of Environment.

The waters expanding of the shore of Usujiri, situated near the mouth of Funka Bay are heavily influenced seasonally by the water mass interchange between the Oya Current and the Tsugaru Warm Current. Due to the mixture of cold and warm currents throughout the year, a variety of wildlife can be seen inhabiting its waters from season to season. Due to these oceanic changes, as a first in fish species, a variety of wildlife including warm water and cold water inhabiting fish species can be seen between seasons. Moreover throughout the course of a year, it is said that the area has an observed capacity to support diverse wildlife.

On our marine campus we use scuba diving, fish raising, and genetic markers as a weapon challenging question put out by wildlife. Making the ecology of wildlife inhabiting the northern waters clear and suggesting ways to preserve in natural harmony the ocean and its inhabitants is our objective.
