Marine biology and sustainable aquaculture sample courses

  • MBAQ 301 Sustainable Aquaculture Techniques I: Growing Shellfish and Finfish

    This course covers the theory and practice of aquaculture techniques used in growing shellfish and finfish in both freshwater and marine habitats. Topics covered will include species identification, habitat creation, reproduction, hatchery and nursery operation, and growth promotion. Additionally, students will learn how to manage the health of aquaculture organisms, harvesting principles and techniques, processing procedures, and identifying appropriate markets for sale. Discussions will be based on the biological, chemical, and economic aspects of aquaculture with a strong emphasis on sustainability, underscoring techniques which minimize environmental impact while maximizing human and animal welfare. Students will assess best-practices in the industry which meet sustainability goals.

  • MBAQ 307 Ichthyology and Fish Health

    Learn an overview of freshwater and marine fishes, their diversity, behavior, and health. You’ll learn about the evolution, morphology, physiology, and life history of the global diversity of fishes, with an emphasis on integrating knowledge of fish anatomy and physiology in relation to their survival and wellbeing. Study major diseases of captive-raised and farmed fish, including pathogenic control measures. Additionally, we’ll explore the relationship between host, pathogen, and the environment, and explore methods for disease diagnosis and management for fish, including basic biosecurity protocols.

  • MBAQ 310 Marine Mammal and Seabird Biology

    Explore the identification, evolution, anatomy and physiology, population biology, behavior, and ecology of marine mammals and seabirds. We’ll look at the breadth and evolutionary history of all marine mammals and seabirds, with an emphasis on what makes each family and species unique. You’ll become familiar with the primary literature in the field and refine your critical thinking and public speaking skills. Conduct multiple research projects throughout the course related to the biology and ecology of these species, with a focus on conservation and ecology. You’ll also learn of the many sampling techniques used from land and sea platforms and discuss how their data impacts the health and survival of these important organisms.
