Brown Trout – Salmo trutta
Description: Brown Trout are a game fish found through out the UK. Farmed on a huge scale globally and are one of the most widespread fish species in the world. Some fish become anadromous and become a Sea trout, changing their appearance to that similar of a Salmon. An aggressive fish that will eat a variety for foods including small fish. Some become solely fish eaters and are known as ‘Ferox’ Trout in Scotland surviving solely on a diet of Arctic Char.
Maximum Size: Upto 24″ but on average 12-16″ when mature.
Environment: Brown 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. Brown Trout are popular for use in aquaponics systems due to their fast growth and food consumption. They will eat smaller fish!
Trout require year round feeding, even in the lowest temperatures.
Water Conditions: Brown 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.
