5.9 Fish Farming

Fish contains high proteins and also low fat. They are also efficient at turning the nutrients into fish mass.
Fish farming will result in increasing the yield of the fish by controlling these factors:

• allow us to control the quality of water 
• controlling the amount of predators 
• controlling the pests 
• controlling diseases

- However the higher the density of fish, the higher the chance that disease will spread. Farmers control this by use of antibiotics and pesticides to keep away pathogen carrying pests . These antibiotics are concerns to human health. 

- Abundance of fish also makes pest and requires farmers to use pesticides which are also concern to the human health.
