About our trout

We have 5 female trout, all of whom joined us from Northern Trout in March 2016.

How we care for our trout

Our brown trout are housed in a 7000 litre tank in our Wildlife of the World corridor.

Their water is kept cool using a chiller, and maintained between 13°c and 15°c. The pH is maintained at approx. 8.2. The water is filtered using an Aqua Medic external filter, with the water runing through a wier to the external filter, where it is processed through a biological filter and the option of UV filtration. Four ocean runners create a current to mimic a river flow. The tank has artificial rockwork and reeds, to create a complex and varied habitat.

Our trout are fed on a complete trout pellet.

The brown trout share their tank with grayling and stone loach.
