| Details: | Dr. Ohs joined the IRREC faculty in July 2005. His research focuses on evaluating new management practices to maximize production or profitability of existing aquaculture operations and evaluating the potential of producing new aquaculture species. In addition, Dr. Ohs has conducted many studies on the nutrition of fish and crustacean species from larval to adult stages of development. He also has research interests in fish and crustacean physiology, endocrinology, larval nutrition, food science, and marketing. | |
