Join us for an Institute of Aquaculture lunchtime seminar which will also launch the beginning of a series of events promoting intellectual exchange between Japan and Scotland.

Professor Hideaki Nakata's earlier research interest involved physical-biological interactions in the oceanic fronts and their implications for the recruitment of marine fish populations. It has been revealed from intensive field surveys conducted in the Kuroshio Front and other coastal regions that water circulation associated with the oceanic fronts could have a significant role in egg and larval retention in the nursery areas, and that enhancement of primary production in the vicinity of the fronts could increase food availability of fish larvae in a critical stage, thereby enhancing larval survival and subsequent recruitment success. In addition, behavioural responses of tuna fishes to the seasonal change in vertical water temperature profiles were also investigated using a bio-logging method.

In recent years, his research gives more focuses on coastal environment, since it is of great importance for spawning and nursery grounds of many fisheries resources. Most of the coastal habitats and nurseries in Japan are suffering from severe degradation of the ecological quality as a result of past human impacts. Excessive eutrophication and its secondary effects such as harmful algal blooms and hypoxia formation in the bottom water could be most serious for fisheries production, in the context of global changes in climate and oceanic conditions. It is therefore an urgent task to restore and enhance the ecological quality of the Japanese coastal water and to look at the possible way of adaptation to the global changes. From this viewpoint, he has been engaged in ecosystem-based management of the coastal environment, aiming at sustainable fisheries and aquaculture production.

This event is supported by the Japan Foundation.

This event is open to staff, students and members of the public.
