Aquaculture is the practice of rearing, breeding and subsequent harvest of aquatic species, which can either be animals or plants, in a controlled aquatic environment such as oceans and manmade ponds and tanks. Indeed there are a number of purposes that the practice of aquaculture serves and some of these are such as the fact that it helps in the restoration of endangered species, food production, building of aquariums plus a number of other environmental benefits that actually come along with the practice. Read on and see some of the types of aquaculture and how they happen to be important.
The practice of aquaculture in which there is the use of marine water is that which is known as mariculture. Generally, mariculture can be practiced close to an ocean in which case there is a part of the ocean sectioned off or still can be practiced in a pond separate from the ocean but this will be such that contains sea water anyway. You can have aquatic species of various kinds bred in these ponds such as molluscs, sea foods such as prawns and shellfish and the other sea plants such as seaweed. These seaweeds and animals bred have a number of uses in the manufacturing industry as such contribute a lot to the economy. Collagen collected from the seaweed is an ingredient used in the cosmetic industry for the manufacture of beauty products such as facial creams and the pearls that are picked from the molluscs happen to be used for the making of fashion items.
The other kind of aquaculture that is rather common is that of fish farming. Talking of fish farming as a form of aquaculture, this is generally the practice of selective breeding of fish, either in fresh or sea water with the main objective of getting an alternative food source. In fact this is the very reason why it has proved to be so popular, given the fact that it provides an alternative source of cheap protein.
Integrated multitrophic aquaculture, as well known as IMTA, is the other type of the practice of aquaculture. By and large, this is one system of aquaculture that happens to be a little more complex looking at the fact that in it there will be a mix of the different trophic levels in the system to avail different nutritional needs for the organism that will be in the system. Generally speaking, IMTA is considered an efficient system looking at the fact that with it there is actually created an environment that is somewhat a replica of the natural habitat.
