Advantages:
Sustainable Fishing
Higher yields (no Anaerobic Gill Disease) due to freshwater paths
No waste Food due to auto feeder and Infrared Technology
Each Generation Artificially selected to only obtain fish with highest possible yield and disease resistance, increasing yield.
Can be genetically modified to have a 10 fold size increase, and can be made to grow on less nutrients and be more disease resistant.
- Increased growth of fish in hatcheries, due to artificially fertilizing eggs, leading to higher chance of fertilization, as in the wild only 10% of eggs are fertilized.
Disadvantages
- High doses of antibiotics used, leading to bio-accumulation in humans that consume it
- Indoor Hatcheries lead to bio-accumulation of Heavy metals
- Large amount of freshwater used in indoor hatcheries, which means with out an on-site recyclers process is very expensive
- unknown consequences of genetic engineering
- Outdoor Hatcheries leads to competition between wild fish and farmed fish (even though still in nets, food, oxygen and space is still being consumed)
- Environmental impact of large wastes concentrated in one area
- Easy for disease to spread due to low spatial equality, leading easy transmission from host to host.
- Small spaces leads to fin and tails being damaged due to rubber with nets or walls of hatcheries.
