- There is an increased demand for seafood, this is putting a large strain on wild fisheries.
- Fish farms are being researched and implemented to reduce the pressure on wild fish populations.
- There are two main challenges to creating a sustainable fish farm: feeding the fish and maintaining water quality.
- Fish farms require large amounts of food.
- Sustainable fish farms should grow foods that can feed the farmed fish.
- Fish waste can build up in a fish farm.
- Sustainable fish farms need to have a constant flow of ocean water through them to prevent waste build-up.
- Waste and excess nutrients are removed from the water in sustainable fish farms before being returned to the ocean.
- Fish farms need to ensure the water being returned to the ocean is free of waste and excess nutrients.
