6
Q
List the requirements for Extensive Aquaculture
A
- Less labout intensive
- Requires less capital investment
- Fish are grown in oceans, lakes, or rivers instead of tanks
- Stocking densities are kept low
7
Q
List the requirements for Intensive Aquaculture
A
- Requires much more human input
- Stocking densities are high and frequent feeding is carried out
- In tanks and ponds, water filtration systems are used to remove waste and supply oxygen
- Productivity is high
