Marine biology and sustainable aquaculture involves the study of ocean ecosystems and the cultivation of aquatic organisms in eco-friendly ways. Marine biology explores the behavior, genetics, and habitats of marine species, contributing to conservation efforts and understanding biodiversity. Sustainable aquaculture focuses on farming fish, shellfish, and seaweed with minimal environmental impact, ensuring food security and protecting marine environments.
The Bachelor’s in Marine Biology and Sustainable Aquaculture prepares students for a broad range of careers helping protect, preserve, maintain, and grow marine organisms and environments. Graduates can obtain employment immediately after graduation with private firms, aquariums, and various government agencies as marine animal trainers, aquaculture scientists, and fisheries technicians.
This degree provides students with a broad emphasis on both marine biology and aquaculture and encompasses coursework with the rigor to prepare students for further study in graduate school or even starting their own aquaculture enterprise.
