Research outline

(1) “Impacts of ocean climate change (warming and acidification) on marine animals” Atmospheric concentration of carbon dioxide has been rapidly increasing in the last 250 years, due largely to fossil fuel burning and cement production. This has led to warming and increasing acidity (termed ocean acidification) of oceans. There is increasing concern upon potential impacts of these ocean environmental changes, whereas we presently know very little about it. We are experimentally investigating how increasing seawater temperature and acidity affect marine animals by rearing different marine animals under simulated future oceanic conditions.

(2) “Vertebrate evolution from aquatic to terrestrial life”. This is one of the long-debated major questions in zoology. We have tackled this issue using mudskippers as model animals for the last 20 years. From 2013, we have expanded our targets, including a variety of air-breathing fishes to study their anatomy and physiology. These include swamp eels in Japan and Vietnam, mudskippers and Pangasius catfish, both major aquaculture fish in Vietnam, and even planning to study electric eels in Amazon. Many questions remain unresolved.
