Fish loss can be very discouraging for beginners of fish keeping, so indirectly, fishless cycling can also help beginners get a good start. Cycling aquariums using feeder fish is risky, because it infects the aquarium with any disease or parasite they happen to have. Fish raised as feeders do not get the same degree of care as non-feeders.
All RAS relies on biofiltration to convert ammonia (NH 4 + and NH 3) excreted by the fish into nitrate. [4] Ammonia is a waste product of fish metabolism and high concentrations (>.02 mg/L) are toxic to most finfish. [5] Nitrifying bacteria are chemoautotrophs that convert ammonia into nitrite (NO 2 −) then nitrate (NO 3 −).
A fish with swim bladder disorder can float nose down tail up, or can float to the top or sink to the bottom of the aquarium. [2] Swim bladder disease is a very common illness within aquarium fish that results in the bladder not functioning properly causing the fish to swim upside down.
These bacterial colonies take several weeks to form, during which time the aquarium is vulnerable to a condition commonly known as "new tank syndrome" if stocked with fish too quickly. Some systems incorporate bacteria capable of converting nitrates into nitrogen gas. [6]
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
The source of ammonia in fish tanks is fish's excretion. [1] Fish excrete ammonia as a nitrogenous waste product. A build-up of ammonia in the fish tank leads to ammonia poisoning. Species of ammonia-oxidizing bacteria (AOB) can break down the ammonia and convert it to other, less toxic, nitrogen products.
In 20 communities around Minnesota, the drinking water supply is so contaminated with toxic nitrate from farm pollution that the state has the obligation to change the way farmers fertilize their ...
Ingesting too much nitrite and/or nitrate through well water is suspected to cause methemoglobinemia. [17] 95% of the nitrite ingested in modern diets comes from bacterial conversion of nitrates naturally found in vegetables. [18] However, potentially cancer-causing nitroso compounds are not made in the pH-neutral colon.
