What means Aquaculture?
What species are farmed in aquaculture?
One of the most important parts of the aquaculture process is represented by microalgae. Traditionally known as seaweed, those species are not easy to maintain and grow. On a small scale this can be achieved, but if you want to extend your farming you will encounter problems like their size and preferences in growing properly.
Fish farming represents the most encountered type of aquaculture. Mainly, this technique is used for obtaining various species of fish for food. Fish is usually harvest in tanks, ponds or ocean set-ups. Usually there is grown fish like carp, salmon or catfish, but you can encounter other species depending on the region. As an example, you can see the Bluefin tuna grown in the Mediterranean.
Shrimp farms are usually found in China or Thailand. It is a troublesome area of the aquaculture due to the fact that shrimp is prone to developing certain diseases.
Oyster farming and various other molluscs are part of this industry. Those depend on the environment and not on inputs of fish or other feed. There are various growing techniques that are strictly related on the area and on the species. Usually, those are farmed directly on the beach or suspended from rafts. The harvest process is done by hand due to the fact that molluscs are sensitive.
There are some farmers that opt for growing aquatic reptiles, amphibians and some invertebrates. Anyway, for the industry of aquafarming this is not an important part.
What are the methods used?
Mariculture is defined by the use of seawater in growing marine life forms. Basically, the growing area is set up in the ocean, in a closed section of it or in specially designed ponds. Furthermore, there exists an Integrated Multi-Trophic Aquaculture. This represents a technique that relies on the fact that the waste obtained from a certain species is used as food or fertilizer for another. It is a method that creates a certain balance in the environment of the growing process.
