These compounds can be added to the fish tank water and eliminate theronts and tomonts but do not affect the trophont stage in the fish skin. The toxicity of hydrogen peroxide is increased at higher temperatures. Sodium chloride when applied in a concentration of at least 7.5 g/L inhibits production of infective theronts in tomocysts. [12]
[7] [14] Some have argued the production of reactive oxygen species like hydrogen peroxide may be responsible for gill damage. However, research suggests hydrogen peroxide concentrations are far too low to have significant effects on fish. [15] Mucus production is another proposed, but poorly supported, mechanism for fish mortality. [7]
Bathing fish with hydrogen peroxide (350–500 mg/L for 20 min) will remove mobile sea lice from fish. It is environmentally friendly since H 2 O 2 dissociates to water and oxygen, but can be toxic to fish, depending on water temperature, as well as to operators. [61]
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
One of the treatments for parasite infestations involved bathing fish in hydrogen peroxide, [65] which can harm or kill farmed fish if they are in a weak condition or if the chemical concentration is too strong. A 2008 meta-analysis of available data shows that salmon farming reduces the survival of associated wild salmon populations.
A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution (NH 4 OH, or NH 3 (aq)), and 30% hydrogen peroxide. [2] [3] As hydrogen peroxide is less stable at high pH than under acidic conditions, NH 4 OH (pH c. 11.6) also accelerates its decomposition.
Piranha solution, a dangerous mixture of sulfuric acid and hydrogen peroxide known to aggressively dissolve organic material, draws its name from these legends surrounding the piranha fish. A common falsehood is that they can be attracted by blood and are exclusively carnivores. [41]
A medicated fish bath (ideally using aquarium merbromin, alternately methylene blue, or potassium permanganate and salt), [5] is generally a first step, as well lowering the aquarium temperature to 75 °F (24 °C) is a must, since columnaris is much more virulent at higher temperatures, especially 85–90 °F.
