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.
