Various Aquaculture systems

The open-net method

The open-net is one of the most controversial systems you can find all around the world. This is due to the fact that it represents a risk for the environment in which it is placed. An open-net system allows uncontrolled interaction between the farm and the environment.

This may turn out harmful for the species that live in the area. This method is regularly used in freshwater lakes and it is used for growing salmon. The risks derive from the fact that waste and other bacteria are released in the surrounding water.

Closed Systems

This type of system is focused on how to control the contamination of the environment. It usually has a barrier that does not allow your farm and the waste produced to escape. The closed system is perfect for sustaining the environment and preventing cross-species contamination.

The Raceway Method

For those that aim for growing rainbow trout, a raceway system is the perfect choice. Its design uses natural streams or wells ( where is the case) in order to redirect the water in the farm. If the waste is properly controlled, this method may be thought about as a low-risk for the environment.

The Recirculation Method

The Recirculation system is known for its usage of the same water. The principle here is not to waste anything, so the water is reused. This is an environmental friendly method because it represents an enclosed system that does not transfer bacteria, waste or fish escapes. With this method you can grow a variety of fish.

Pond Systems

For a regular household, a pond is the most popular method of establishing a fish farm. Usually, ponds are enclosed waters, but there are some cases when they communicate with another body of water. If the waste is properly removed, there are no risks for nearby ecosystems. In ponds you can grow mostly tilapia, but catfish or shrimps can do a great job too.

Suspended Systems

For certain crustaceans the suspended method can be more than benefic. If you are considering growing shellfish, you may want to know that in this case you will only have to provide fresh water. Usually, those represent little to no risk if the area in which you grow them is part of their natural habitat. By using the suspended systems you can grow oysters, mussels and clams, too.
