Overview

Declining fish numbers in recent years have become a problem for many fish species. Recovering stocks requires an understanding of the amount of food resources required for each fish species as well as the current state of the stock of those fish species. There is also a need for collecting ecological information during the egg and larva stages, which are prone to mass mortality, and managing resources appropriately, such as preventing overfishing, when resources are declining.

In our laboratory, we are exploring methods for predicting resource fluctuations by collecting information on the ecology and marine environments of aquatic organisms. We are trying to achieve the sustainable use of marine resources around Tsugaru Strait through these methods. We are currently studying Pleurogrammus azonus, Lophius litulon, and Todarodes pacificus.
