What are the types of systems used in Aquaculture production
• Earthen ponds • Raceways • Cages and net pens • Re-circulating tank system • Underwater lease
List 2 advantages and disadvantages of earthen ponds
Advantages: • The water is free or “cheap” • There is no need to circulate water Disadvantages: • Minimal control of the environment • High risks of predation
List two advantages and disadvantages of Raceway production
Advantages: • Uses free water from river or other source • Use flow to maintain water quality Disadvantages: • Poor control of water source • Effluent concerns
List two advantages and disadvantages of the cage system
Advantages: • Easy to harvest • Tidal flush provides free water exchange Disadvantages: • Susceptible of storm damage • Exposure to predation
List two advantages and disadvantages of Re-circulating system
Advantages: • Elimination of predation • Complete control of the environment Disadvantages: • Requires expensive investment and management • Loss of water kills all the species within minutes
List two advantages and disadvanatges of underwater lease
Advantages: • Free water • Free feed Disadvantage: • Storm damage • Changes in salinity

List 3 potential solutions for aquaculture to grow
• Establish an Economic Aquaculture Development Potential solutions for aquaculture to grow • National Economic Aquaculture Development that does not just focus on research but target aquaculture as an economic tool • Eduacation (better education) to understand the culture • Pemetting process need to be shortern
