"Owners of a fish farm near the village of Alresford have been raising
fish for nearly 30 years. Recently they noticed some of their brown
trout appeared to be missing. Then a local wildlife photographer and
friend of the fish farmers made an amazing discovery.

Dennis Bright captured images of the trout leaping 3 feet out of the
water into the mouth of an 8 inch wide metal feeding pipe. The pipe
leads to a tributary of the River Itchen about 30 feet away. To get to
the water, the trout had to leap into the tiny metal pipe then swim
against the swift current."
