Learn to raise freshwater fish

Advantages of Aquaculture

  • Helps overcome a deficiency in seafood supply.
  • Efficient production of a protein-rich food source.
  • Source of Income.
  • Flexible method.
  • Promotes tourism.
  • Reduction of diseases transmitted through wild food sources.
  • Facilitates waste reduction and recycling.
  • Increasing production of a species through aquaculture as opposed to fishing for it will aid in the protection of marine species being over exploited and help reduce pollution of coastal waters.

Learn about the Different Forms of Aquaculture

There are a lot of different terms used to describe growing fish, each with a subtly different connotation.  pisciculture, aquaponics, aquaria or aquaculture are all terms used for growing fish in controlled systems. 

  • Aquaculture is an all embracing term, covering fish, crustaceans, shell fish and other species, including seaweed. It is farming fish and other water dwelling plants or animals - in fresh water or salt water to harvest.
  • Pisciculture is farming fish only (excludes crustaceans, molluscs, seaweed etc.)
  • Mariculture is aquaculture in saline water.
  • Aquaponics involves growing land plants such as vegetables and herbs together with fish, all in the same system (usually in tanks) using (nutrient loaded) water circulated from the plants to the fish, and then returned to the plants. It is a hybrid of hydroponics and aquaculture.
  • Aquaria: Aquarium management or aquaria generally refers to growing plants or animals in water for purposes other than harvesting for food, such as conservation, research, a hobby or decoration.


Applications of Aquaculture

  • Commercial fish farming
  • Fish farming as a tourist attraction
  • Keeping fish as a hobby
Undertaking this course can ultimately be a money saving exercise for many students. If you have limited or no experience in aquaculture, there are many costly mistakes that can be made if you invest time and money before first learning the basics.
