Ruairi graduated from the National University of Ireland Galway with a B.Sc. in Marine Science in 2008 and a Ph.D. in Zoology in 2012. He has been involved in fisheries research projects on a variety of freshwater and marine species in Europe and North America. Ruairi joined Hubbs-SeaWorld Research Institute in 2015 as a Postdoctoral Research Associate to assess the feasibility of replenishing alternative species by stocking. Since 2019 he has been the Stock Enhancement Research Coordinator, working on the Institute’s programs involving white seabass and California halibut. Current research areas include assessment of stock enhancement (though approaches such as quantitative modeling and development of genetic tagging) and efforts to maximize cultured fish quality and survival in the wild (specifically the impacts of early rearing conditions on fish behavior, morphology and sex determination).
