Marine Aquaculture Online Course
Learn how to set up and run a marine aquaculture venture. Marine aquaculture (mariculture) is saltwater fish farming.
- Learn the culture of salt water species of fish, shellfish, seaweed and other marine products.
- Learn to plan and manage the farming of a wide variety of marine life.
- 100 hours self paced study.
Course Aims
- Explain general mariculture production systems
- Discuss the factors involved in setting up a business
- Evaluate factors that need to be considered when choosing marine species for aquaculture in your region.
- Explain the commercial production of finfish
- Explain the commercial production of crustaceans
- Explain the commercial production of molluscs
- Explain the use and production of Seaweeds and Aquatic Algae
- Discuss the role of echinoderms in mariculture. Explore the pharmaceutical uses of marine organisms
- Explain general diet formulation and feeding
- Describe issues related to the health management of marine animals used in aquaculture.
