1. Culture of the natural production of water; fish-breeding as a branch of industry.
2. The science, art, and business of cultivating marine or freshwater food fish or shellfish; such as, oysters, clams, salmon, and trout, under controlled conditions.
3. Another term for hydroponics [hydro-, "water" + (geo)ponics]; a technique of growing plants (without soil) in water containing dissolved nutrients.

1. An underground bed or layer of earth, gravel, or porous stone that yields water.
2. Permeable underground rock stratum which holds water.
3. Any geological formation containing or conducting ground water; especially, one that supplies the water for wells, springs, etc.

The pore spaces in aquifers are filled with water and are interconnected, so that water flows through them. Sandstones, unconsolidated gravels, and porous limestones make the best aquifers. They can range from a few square kilometers to thousands of square kilometers in size.

2. Water-bearing stratum.

2. Plant communities that are influenced by the presence of groundwater in damp meadows.

1. A leaky confining bed that transmits water at a very slow rate to or from an adjacent aquifer.
2. A geologic formation that may contain ground water but is incapable of transferring that water to the surface.
3. A bed of low permeability adjacent to an aquifer.

An aquitard may serve as a storage unit for groundwater, although it does not yield water readily.

1. The state of being watery.
