Aquaculture Supports a Sustainable Earth - NOAA Fisheries [5] Species that are grown within the methods of sea ranching do not have any additional artificial feed requirements because they are living off of the naturally occurring nutrients within the body of water that the sea pen is set up. Marine biologists often head out on research cruises with other professionals in the field, so they must work well in group environments and with groups in confined spaces.
