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.
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.
An example of deep water culture in lettuce production. Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water.
The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum or 'A Natural History' by Francis Bacon, printed a year after his death.

[183] Fish was an important food source in medieval Europe, when in average 150 days per year were days of fasting and abstinence , and meat was prohibited. [ 184 ]
The amount of organic waste produced by fish farms is also alarming. A salmon farm in Scotland, for instance, is estimated to produce as much organic waste as equivalent to a town of people between 10,000 and 20,000 people each year. [29] Today 50% of the world's seafood is farm-raised. [30]
