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.
Inland saline aquaculture is the farming or culture of aquatic animals and plants using inland (i.e. non-coastal) sources of saline groundwater rather than the more common coastal aquaculture methods. As a side benefit, it can be used to reduce the amount of salt in underground water tables, leading to an improvement in the surrounding land ...
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 ...
Extensive farming can have the following problems: [3] Yields tend to be much lower than with intensive farming in the short term. Large land requirements limit the habitat of wild species (in some cases, even very low stocking rates can be dangerous), as is the case with intensive farming. Less profitable then intensive farming per unit of 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.
They include extensive, semi-intensive and intensive systems. [13] Extensive aquaculture systems are usually conducted in medium-to-large-sized ponds or water bodies. The fish production depends on the natural productivity of the water, making this system low cost and maintenance. With semi-intensive fish farming, the production of fish per ...
The terms "IMTA" and "integrated aquaculture" differ primarily in their precision and are sometimes interchanged. Aquaponics, fractionated aquaculture, integrated agriculture-aquaculture systems, integrated peri-urban-aquaculture systems, and integrated fisheries-aquaculture systems are all variations of the IMTA concept.
