Aquacultural engineering is a multidisciplinary field of engineering and that aims to solve technical problems associated with farming aquatic vertebrates, invertebrates, and algae. [1] Common aquaculture systems requiring optimization and engineering include sea cages, ponds, and recirculating systems. [2]
The Blue Revolution refers to the significant growth and intensification of global aquaculture production—domestication and farming of fish, shellfish, and aquatic plants—from the middle of the 20th century to the present, particularly in underdeveloped countries. [1]
Mariculture, sometimes called marine farming or marine aquaculture, [1] is a branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in seawater. Subsets of it include ( offshore mariculture ), fish farms built on littoral waters ( inshore mariculture ), or in artificial tanks , ponds or raceways ...
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.
According to the FAO, "...a fishery is an activity leading to harvesting of fish.It may involve capture of wild fish or raising of fish through aquaculture." It is typically defined in terms of the "people involved, species or type of fish, area of water or seabed, method of fishing, class of boats, purpose of the activities or a combination of the foregoing features".
An increase in upwelling index over the period 1985–2009 was documented in all studied regions while additionally upwelling intensification were observed in the south. [257] A continuous increase in water temperature, ranging from 0.1 to 0.2 °C per decade has also been documented. [258] [226]
In terms of outputs, an aquaponics system may continually yield plants such as vegetables grown in hydroponics, and edible aquatic species raised in an aquaculture. Typical build ratios are .5 to 1 square foot of grow space for every 1 U.S. gal (3.8 L) of aquaculture water in the system. 1 U.S. gal (3.8 L) of water can support between .5 lb (0. ...
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.
