Rainbow Trout – Oncorhynchus mykiss
Description: The Rainbow Trout is a popular game fish. Distinguishable by its pink stripe and spotted pattern. They have become popular pond fish over recent years with the gold and blue variants becoming available. They can be piscivorous so caution should be taken if introducing with small fish. The Rainbow trout is widespread throughout the world.
Maximum Size: Upto 24″ but on average 12-16″ when mature.
Environment: Rainbow Trout are very quick growing and require a large pond (10000 litres/2200 Gallons+ ideally). All trout require good filtration (as would be for a large koi pond) and airpumps supplying plenty of oxygen. They will require some shade in the summer months. Trout are popular for use in aquaponics systems due to their fast growth and food consumption.
Trout require year round feeding, even in the lowest temperatures.
Water Conditions: Rainbow Trout require a pH range of 7-8.5, Ammonia and Nitrite to be virtually 0ppm and dissolved oxygen saturation to remain above 8ppm. They are intolerable to lower oxygen saturation values and susceptible to high water temperatures above 22°C.
As with any pet, please fully research for yourself to ensure that you can accommodate a fish of this type in your home.
