By contrast, an extensive property or extensive quantity is one whose magnitude is additive for subsystems. [4] Examples include mass, volume and Gibbs energy. [5] Not all properties of matter fall into these two categories. For example, the square root of the volume is neither intensive nor extensive. [1]
Extensive aquaculture is the other form of fish farming. Extensive aquaculture is more basic than intensive aquaculture in that less effort is put into the husbandry of the fish. Extensive aquaculture is done in the ocean, natural and man-made lakes, bays, rivers, and Fiords.
The extensive aquaculture is mainly characterized by increased dependence on natural food in the process of producing the stock (Bunting et al.). The Semi-intensive production, on the other hand, is primarily based on the fertilizer applications; this is done in order to improve the natural food production and to maintaining the use of low ...
Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area.
Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. [2] Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems.
Integrated multi-trophic aquaculture (IMTA), also called integrated aquaculture, [52] is a practice in which the by-products (wastes) from one species are recycled to become inputs (fertilizers, food) for another, making aquaculture intensive. Fed aquaculture (e.g. fish and shrimp) is combined with inorganic extractive (e.g. seaweed) and ...
An intensive property does not depend on the size or extent of the system, nor on the amount of matter in the object, while an extensive property shows an additive relationship. These classifications are in general only valid in cases when smaller subdivisions of the sample do not interact in some physical or chemical process when combined.
Recirculating aquaculture systems often involve intensive, high-density culture of a species with limited water usage and extensive filtration. In a typical recirculating aquaculture system, a series of filtration steps maintains a high level of water quality that promotes rapid fish growth. [ 6 ]
