Nanae Fresh-Water Station新着情報

      This station was established as one of the field stations named Nanae Fish-Culture Experimental Station, belonging Faculty of Fisheries, Hokkaido University at 1959.  This station becomes to be one of the field stations at 2001, when Field Stations belonging Faculties of Fisheries, Agriculture, and Science, Hokkaido University were integrated to Field Science Center for Northern Biosphere.  The name of this station was changed to present one.  At 2011, old square ponds were reconstructed to new circular ones.  Construction of new building is expected to start in this spring. 

      This station has been used for education and research of fundamental biology concerned with artificial reproduction of fish species, and conservation of natural genetic resources of fish.  Advanced biological researches were performed in this Nanae Fresh-Water Station.  ­At the beginning of this station, biology and techniques of common carp aquaculture were educated to the students of faculty of fisheries.  Biology of Salvelinus species collected from all over Japan began to study in this station around 1970’s when population of the fish had been decreasing because of the general development of national land.  Around 1980’s, chromosome set manipulation techniques, including sex control, of cultured fish were established in Faculty of Fisheries and this station. From late 1980’s to 1990’s, bio-chemical studies of fish reproduction have been conducted in this station.  During the study, it has been becoming to elucidate that artificial materials activate some endocrine system of fish, resulting in discovery of endocrine-disrupting chemicals, namely “environmental hormone”.

      Many undergraduate and graduate students use this station, facilities and fishes for their student experiments, field training and researches of their master and doctoral thesis, concerned with developmental biology, genetics, endocrinology, physiology of reproduction and nutrition, fish ethology, fish pathology and so on.  Educational programs for elementary school and junior high schools are also performed. 

      In national universities, social requirements of active contribution to education and research have been gradually increasing after they were incorporated.  We want to meet those requirements as much as possible.  Do not hesitate to ask for research cooperation.
