The main variations of fish farming systems
There are several types of fish farming systems, the farmers can use one system or several at the same time. There are two main fish farming systems: extensive and intensive systems.
Extensive system: as an example, we can mention a pond or irrigation ditch system. The main feature of such system is that it is installed in a semi-natural environment, with a natural food supply to the cultured fish. The farmer can regulate the environment of the pond with the help of different fish species and special equipment.

There is also such type of extensive system of fish farming as "re-stocking" of natural populations. In this method, the fish is raised in tanks and then it is released in the wild to feed, but recaptured after receiving marketable size.
As for the intensive system of fish farming, this can be, for example:
- Completely closed system that is called integrated recycling system
- Flow-through/raceway that is called semi-closed system
- Open system that is called floating cage system
Often farmers use closed-circulation tanks or flow-through raceways in such types of systems. There is also floating sea cages, that are open to the natural environment, and they are also related to intensive systems. See also: How to rear catfish at home

In this type of fish farming system, a farmer can easily control water quality, oxygen, and food supply. Most of the closed-circulation tanks are equipped with water purification systems.
The intensive system is considered as a high-cost method of fish farming, but it provides much higher rates of productivity. The disadvantage of this system is that the stocking density can become the factor that increases the risks of diseases among fishes.
There is also one more system that is called “flow-through system” it is also known as classic fry farming, in this system the species of the fish are raised in tanks and then released.
