Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.
Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [2]
Plants are grown in aquaponics systems, with their roots immersed in the nutrient-rich effluent water. This enables them to filter out the ammonia that can become toxic to the aquatic animals, or its metabolites. After the water has passed through the hydroponic subsystem, it is cleaned and oxygenated, and can return to the aquaculture vessels. [2]
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. Two examples of AOB are Nitrosospira and Nitrosomonas. [2] The amount of ammonia present is usually accompanied by a rise in pH. As ammonia is a base ...
Aquariums are usually much more densely stocked with fish than the natural environment. This increases the amount of ammonia produced in the relatively small volume of the aquarium. The bacteria responsible for breaking down the ammonia by converting it to nitrite, Nitrosomonas, colonize the
Aquatic plant management involves the science and methodologies used to control invasive and non-invasive aquatic plant species in waterways. Methods used include spraying herbicide , biological controls , mechanical removal as well as habitat modification. [ 1 ]
