Mark is currently a Senior Research Scientist at Hubbs-SeaWorld Research Institute (HSWRI) in San Diego, where he has been employed since 1989. Mark also serves as the Director of the Institute’s Sustainable Seafood Program, which is focused on developing techniques for growing marine finfish for ocean replenishment and farming. The HSWRI aquaculture research program supports approximately 20 full-time staff, two research hatcheries in San Diego, and acclimation cage facilities throughout southern California coastal waters. Species currently being investigated for farming include white seabass, striped bass, California yellowtail, and California halibut.
Mr. Drawbridge graduated from Gettysburg College in Pennsylvania in 1985 with a B.A. degree in biology and from San Diego State University in 1990 with an M.Sc. degree in Marine Ecology. In addition to his direct responsibilities at HSWRI, Mark is a current board member and past-president of the California Aquaculture Association; an associate faculty member at the University of San Diego; a member of the Western Regional Aquaculture Center’s technical research committee; and a member of California’s Aquaculture Development Committee.
