[2] Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems.
Aquaculture technology is varied with design and development requiring knowledge of mechanical, biological and environmental systems along with material engineering and instrumentation. [4] Furthermore, engineering techniques often involve solutions borrowed from wastewater treatment , fisheries, and traditional agriculture.
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.

This offers a valid solution to the problem of limited access to resources and this is why the urban aquaculture should be more widespread and encouraged for all the ...
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.
