The approach of using large man-made tanks that are placed inside a greenhouse with hydroponic beds that are placed near the tanks is circulated to the hydroponic beds, where the fish feed waste goes to provide nutrients to the plant crops that are grown in the hydroponic beds. The majority of types of plants that are grown in the hydroponic beds are herbs which are natural and organic to fish.
The innovative type of fish farming method is very modernized to the traditional “flow through system”, a system when sport fish species are raised from eggs and are put in streams and released.
There are a number of different fish species that are raised on fish farms, the most common fish spices raised are salmon, carp, tilapia, catfish and cod.
Advantages to indoor fish farming
• Fish are protected from predators and weather changes.
• Fish are often produced faster through temperature control, water quality and feeding practices.
• Indoor fish farming is often considered more environmentally friendly because it requires less water and produces less waste.
• Avoids the chance of fish escaping and getting loose amongst wild fish populations.
• Allows higher stock densities and often saved farm labour input costs.
• It often allows greater flexibility for facility locations, which can save transportation costs if facilities are located near markets.
