Marine Science Graduate Program

Mark A. Drawbridge

Senior Research Scientist, Hubbs-SeaWorld Research Institute

Mr. Drawbridge studies factors that affect the reproduction, growth and health of fishes in an aquaculture setting. Stock enhancement is a particular interest, and his research focuses on the process of raising finfish for eventual introduction into the ocean. He has examined the role of diet, exercise and environmental conditions in the hatchery production of finfish.

Scholarly and Creative Work

Drawbridge became involved with HSWRI in 1986 while participating in the Institute’s nearshore fish surveys as part of his Master’s Degree research. Prior to completing his degree at San Diego State University in 1990, he spent a year of his graduate program at the University of Queensland in Queensland, Australia.

Hubbs-SeaWorld Research Institute hired Drawbridge in 1989 as research technician for the Ocean Resources Enhancement and Hatchery Program (OREHP) field assessment program. In 1999, he began to direct the Institute’s aquaculture and fisheries research programs. These programs currently support over 30 full-time employees at facilities located in San Diego, Carlsbad, Catalina Island and Mexico.
