Explanation should include
- factors in site selection (e.g., depth of water, water quality, prevailing winds, natural currents)
- species suitability
- source and materials
- rearing aquaculture species inside confined enclosures (to include cages, net pens, baskets, etc.) in freshwater and marine environments
- types of cages (i.e., fixed, floating, submersible, and submerged)
- cage requirements (vary by species and location)
- engineering/construction (to incorporate cage design requirements)
- cage maintenance
- clean fish cages in accordance with BMPs (routine scrubbing)
- use anti-fouling materials
- arrange and secure fish cages in the pond
- preventive controls/biosecurity
- advantages of cage culture
- disadvantages of cage culture
- stocking densities based on species and cage size
- factors in production
- species selection for cage culture
- salmon
- catfish
- tilapia
- trout
- striped bass
- red drum
- bluegill
- carp
- feeding methods for cages (feeding ring).
