Generally it is aquaculture in marine environments. If one takes a closer look there are different definitions. Some limit mariculture to the raising of marine plants and animals in the ocean itself (EEA, 2008[2]). Others also include species from brackish water and include culture methods that take place in salty and brackish water that is not situated in the ocean (CBD, 2004[3], Wecker, 2006[4]).

Mariculture includes a wide range of species and culture methods. It is growing fast on a global scale . This is due to the fact that many fish stocks are overfished and catches are declining . At the same time the world population is rising and with it the need for dietary protein. The expansion of mariculture can reduce pressure on wild fish, shrimps and molluscs
