Current Research Interests
Evaluation of marine stock enhancement programs (MSE):
I have long studied the effects of Japan MSE using survey sampling and population genetics methodologies. In collaboration with my colleagues, I collected samples of red sea bream, Japanese Spanish mackerel, herring, and Manila clam, and evaluated the ecological and genetic effects of the large-scale releases on wild populations. Currently, I am reviewing the status of Japan and worldwide marine stock enhancement programs.
Statistical methods for MSE, population genetics and genomics:
Hirohisa Kishino and I have developed statistical methods for estimating survival rates from mark-recapture, total landings from hatchery releases and recreational fishery, and mixing proportions and genetic population structure. Sampling theory, maximum likelihood, and Bayesian inference have been used in our methods. We are developing methods for estimating fine-scale population structure for high gene flow species and for detecting genomic selection for environmental adaptation.
Ecology of marine species and response to environmental changes:
Katsuyuki Hamasaki and I have investigated early life history, behavior, ecology, and population genetics of the diverse terrestrial hermit crabs using field surveys and laboratory experiments. My current research interests include how marine populations respond to anthropogenic and natural disturbances, and climate changes.
Many thanks to:
My friend, colleagues and students for collaboration of field sampling and laboratory experiments. I thank Kate Myers for opportunity of my research in 2000 at School of Aquatic and Fishery Sciences, University of Washington.
