Design elements must consider changing environmental condition, and its effect on growth and survival. To aid in the quantification of biological data, underwater videocameras and imaging analysis systems were developed in Dr. Petrell's fish image laboratory. They have been used to gather information on how large populations of fish feed and distribute within an enclosed space. Collaboration with the Graduate Fisheries Centre helps bring the research work into contact with well-known fisheries biologists. The research areas tend to be interdisciplinary in nature.
Team work is usually essential.
