Department of Living Marine Resources

Popular fish, such as sardines and mackerel, are always on the market, and supplies therefore appear to be stable. In reality, most popular fish are sometimes superabundant, and sometimes extremely scarce. It has become clear that the ocean ecosystems supporting productivity of marine life change drastically with climatic variations. The main research themes of the Department of Living Marine Resources are the mechanisms linking physical environments and stock fluctuations (Fisheries Environmental Oceanography), reproductive and early life ecology of fish and shellfish (Biology of Fisheries Resources), and stock assessment and fisheries management for sustainable use of bioresources (Fish Population Dynamics).
To explore the mechanisms controlling distribution,transport and variations of living marine resources, we study the dynamics of physical oceanographic processes and physical-biological interactions by field observations, laboratory experiments and numerical simulalions
Using mathematical modeling, computer simulalions and statistical analyses of the survey dala,we study the mechanisms of population fluctuations,stock assessment for sustainable use, and management of living marine resources.
To elucidate the biological traits of marine living resources underlying the mechanisms of recruitment fluctuations,we investigate physiological and ecological characteristics of adult sexual maturation, and growth and mortality in their early life stages, by field studies and laboratory experiments.
