Research Activities
The distribution, migration and stock variation of marine organisms fluctuate with physical, biological and chemical marine environments on various temporal and spatial scales. Global oceanic and climatic phenomena represented by El Nino have a close relationship with spawning and feeding migrations of large-scale migrating fishes that migrate over several thousand kilometers. Biological transport associated with ocean circulation and vertical mixing caused by oceanic turbulence play very important roles in the growth and survival of larvae and small marine organisms. The marine environments that affect not only species but also growth stages vary widely. Our objectives are to clarify the characteristics of oceanic phenomena related to ecology of marine organisms and to determine the response mechanisms of marine organisms to global environmental changes.

Future Plan
Since the 1996 ratification of the United Nations Convention on the Law of the Sea, Japan has been working on developing a national fisheries management scheme with the introduction of the Total Allowable Catch (TAC) system and the establishment of an exclusive economic zone. The allowable catch is revised annually for each of these species based on the Allowable Biological Catch (ABC) that is calculated based on scientific studies. Prior to the implementation of this system, fish stocks had become a frequent subject of discussion on endangered species at meetings of the signatories of the Washington Convention (the Convention on International Trade in Endangered Species of Wild Fauna and Flora). Under these international circumstances, the Basic Law of the Sea was established in Japan in 2007. If we are to avoid the imposition of misguided international regulations on fisheries based on misunderstandings or erroneous information, we must make an effort to accurately estimate fish stocks by accounting for global environmental changes. On the other hand, it is true that we live in an age in which the international community demands Japan to expressly demonstrate its readiness to develop and adhere to national standards for sensible fisheries. In our laboratory, we will proceed to study topics related to fishery management, conservation of marine environment and ocean policy, in addition to general marine natural science.
Messages to Students
Oceanography is a scientific field that necessitates a multidisciplinary approach. In particular, to clarify the mechanisms of the marine biological response to global environmental change, physical, chemical and biological processes should be studied using various scientific methods including marine observation, numerical simulation, rearing experiments and chemical analyses. Our laboratory teaches these subjects and welcomes all students who wish to study the biological response processes of marine organisms.
