As a result of applying conventional agriculture that involves synthesis medicines, pesticides and GMO’s, the quality of food gave rise to concerns for the world population. In these circumstances organic agriculture has massively developed in the last decades. The features of this new type of agriculture were also used in aquaculture. Therefore, the European decision makers have issued the following legal acts: Regulations (EC) No 834/2007, 889/2008, 1254/2008, 710/2009 and 537/2009. As regulations they shall apply directly in the national legislation. These regulations cover the fields of pounds for aquaculture, specific organic feed and reproduction methods by organic genetic material. Another target of the regulations is the production of an important source of organic feed–seaweed-intended for the feeding of organic farm animals. In Romania the targeted species are the carp and the Asian carp varieties. There is a great potential for the seaweed organic feed. The organic aquaculture interferes in the friendly way with the environment maintaining the natural characteristics of it and also a sustainable agriculture activity.
