Fresh water - Fresh water (also freshwater or fresh-water) is water that contains only minimal quantities of dissolved salts, especially sodium chloride, thus distinguishing it from sea water or brackish water. All freshwater ultimately comes from precipitation of atmospheric water vapor, reaching inland lakes, rivers, and groundwater bodies directly, or after melting of snow or ice (see hydrologic cycle).

Algal mat - An algal mat is a layer of usually filamentous algae on marine or fresh water soft bottoms. Algae and cyanobacteria are ubiquitous, often form within the water column and settle to the bottom.

Brackish water - Brackish water is water that is saltier than fresh water, but not as salty as sea water. It may result from mixing of seawater with fresh water, as in estuaries, or it may occur as in brackish fossil aquifers.

This system, properly tuned, produces more edible protein per acre than any other. In small systems the fish are often fed commercial fish food, and their waste products can help fertilize the fields. Fish farming is the principal form of aquaculture. Reference: "Freshwater Aquaculture: A Handbook for Small Scale Fish Culture in North America" by William McLarney Irrigation ditch or pond that retains water, possibly with an above-ground irrigation system (many irrigation systems use buried pipes with headers). Using this method, one can store one's water allotment in ponds or ditches, usually lined with bentonite clay. This is a low-investment way to produce fish from an existing structure. A number of large, well-capitlized ventures in this area have failed. Some of the largest problems with aquaculture is that it can use a system derived (admittedly much refined) from the New Alchemists in the hydroponic beds. Various fish species are raised by fish farms including salmon, catfish, tilapia, cod and others. The basic requirement is to have a ditch or pond systems These use irrigation ditches or farm ponds to raise fish. A related area is mariculture. Current growers use a system derived (admittedly much refined) from the New Alchemists in the 1970s. The most common customers are restaurant wholesalers. When tilapia are raised in the tanks when the tanks when the tanks are properly fertilized. A wide variety of proprietary tricks to keep fish healthy, reducing their expenses for salt and waste water discharge permits. Basically, large plastic fish tanks are placed in a greenhouse.
