Aquaculture and Mariculture

  • Extensive and Intensive Aquaculture [1]
    • Extensive aquaculture does not require the addition of feed. Examples of this include
    • Intensive aquaculture requires the addition of feed. Examples of this include

Types of aquaculture

  • 1/4 bivalves [2]
  • 1/4 seaweed and algae [2]
    • Largely produced for chemicals [2]
  • 1/2 fish [2]
    • salmon
      • largest market value produced [2]
    • shrimp

Potential Mitigation of Over-fishing

  • Collection of juvenile from wild or incubating in a hatchery
    • Rate of replenishment needs to be sustainable for the ecosystem that the juveniles are collected from [3]
  • Urban aquaculture [4]

Impacts on Coral

  • Current common fishing practice in Indo-Pacific if dropping cyanide in water to stun fish- having disastrous effects on coral [3]
  • Coral reefs are used to provide an ecosystem for aquaculture farming. [5]
  • Aquaculture on Costal Reefs and Related Problems
    • Cage Culture [1]
    • Restocking and Reseeding[1]
    • Artificial Habitat Development[1]

Problems

Pollution

  • Increased pollution along coast from concentration of aquacultures [3]

GMO Salmon

  • AquaBoutny Technologies has created a GMO salmon that grows twice as fast as normal salmon and twice as large [6]
    • regulation issues
    • fear of its escape into the wild
