5.9 explain the methods which are used to farm large numbers of fish to provide a source of protein, including maintenance of water quality, control of intraspecific and interspecific predation, control of diseases, removal of waste products, quality and frequency of feeding and the use of selective breeding.
Fish farming:
1. Fish have low fat and high protein :)
2. Efficient at turning the nutrient into fish mass :)
Advantages: Fish farming will allows us to….
1. Control quality of water = clean
2. Control predators
3. Reduces pests
4. Reduce disease
By controlling the above we contribute to an increase in yield of fish
Where there is a high density of fish, then the possibility of transmission of disease.
Some fish farmers use Antibiotics that is a concern to human health.
The abundance of fish also makes pests common therefore some fish farmers have taken to using pesticides. Also a concern amongst human health
