This lecture is also omnibus by some teachers and researchers. In this lecture, diversity of fish egg and fish-egg products in Japan is introduced. Then, diversity of early development, such as cleavage pattern, mesoderm formation and differentiation of primordial germ cells, is introduced.
This lecture is omnibus by some teachers, researchers and artist. The educational staff of Nanae Lab. introduces about embryology and developmental technology in teleost fish. In this lecture, history of analyzing the mechanism of early development of fish, and its application for recent developmental technology, such as induction of chimeric animals, are introduced.
In this field training, students moved between Sapporo and Hakodate campus by bus or training vessel, Oshoro-maru. When students visit to the Nanae Station, some lectures about aquaculture of teleost fish and field experiments are performed.
In this lecture, two teachers, Prof. H. Ueda and Prof. E. Yamaha belonging to Field Science Center for Northern Biosphere conduct this lecture to the third-year students in Faculty of Fisheries. In the part by Prof. Yamaha, technology of aquaculture is firstly introduced, and then future prospect of aquaculture is discussed in recent study of fisheries science associated with the current technology in agriculture and livestock science.
In this practice, students study about general aquaculture in Hokkaido
at local stations in FSC, namely Usujiri Fisheries Station, Toya Lake Station
and Nanae Fresh-Water Station, and other facilities about aquaculture around
seashore of Hokkaido Prefecture. Students also try to experiment
about reproduction, development and growth in algea and fish, physiological
differentiation concerned with migration of salmonid species, studying
several techniques of aquaculture and interaction between environment and
organisms.
In the Nanae Fresh-Water Station, students try artificial fertilization,
chromosome set manipulation and cryopreservation of sperm. Students
also study otolith marking and its detection.
In this student experiment, several teachers conduct several kinds of biological
experiments associated with aquaculture of fisheries science, such as histology,
genomic analysis, pathology, physiology, reproductive biology, developmental
biology and so on, using teleost fish, invertebrate animals and marine
algae. In the part by Prof. Yamaha, students observe normal development
of cyprinid species from fertilization to hatching. Students also
try to manipulate fish embryo and learn the mechanism of development in
teleost fish.
In this lecture, students study recent biomass and food production by
plant agriculture, forestry, stockbreeding and aquaculture, and their fundamental
biological and ecological system. Students will realize balanced
biomass production between human activity and nature conservation on the
earth.
