The River Test runs through the grounds of Mottisfont and there is a diverted section of it that runs through a very unnaturally straight section of river near the house.  As we walked along the path by this section, we saw a couple of fish in the water.  As we moved on, we realized that there were loads of them.  To my untrained eye, they looked like they might be trout but I am not an angler or any sort of sim expert.  I got some photos of them but video seemed like the best bet so I had a good at that too.  Can you identify them?
