5.1-5.9 Food Production:

• Maintaining water quality: filter water to remove waste and harmful bacteria to prevent disease
• Controlling intraspecific predation: stops competition within the same species, as fish are separated by size and age to prevent competition
• Controlling interspecific predation: stops competition between species, as different species are separated by nets or tanks
• Controlling disease: antibiotics are given to increase chances of survival
• Removal of waste products: water is filtered to remove waste faeces
• Controlling feeding quality + frequency: fish are fed frequently in small amounts so they don't overeat and to avoid food wastage
• Selective breeding: reproduce fish with desired characteristics
