Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater.
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.

The Integrated Aqua-Vegeculture System (iAVs), also informally known as Sandponics, [1] is a food production method that combines aquaculture and horticulture (olericulture). [2]
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.
The origins of microponics can be traced back to the integrated aquaculture experiments conducted by the New Alchemy Institute during the late 1960s and early 1970s. The New Alchemists developed innovative food production models that revolved around the integration of various elements, including fish, plants, ducks, rabbits, and other organisms, all housed within their solar and wind-powered ...
Aquaculture not only impacts the fish on the farm, but it also influences other species, which in return are attracted to or repelled by the farms. [79] Mobile fauna, such as crustaceans, fish, birds, and marine mammals, interact with the process of aquaculture, but the long-term or ecological effects as a result of these interactions is still ...
The main benefit of RAS is the ability to reduce the need for fresh, clean water while still maintaining a healthy environment for fish. To be operated economically commercial RAS must have high fish stocking densities, and many researchers are currently conducting studies to determine if RAS is a viable form of intensive aquaculture.

Integrated aquaculture is a form of aquaculture in which cultures of fish or shrimp are grown together with seaweed, shellfish, or micro-algae. Mono-species aquaculture poses problems for farmers and the environment. The harvesting of seaweed crops in mono-species aquaculture releases nitrates into the water and can lead to eutrophication.
