Gudgeon

The gudgeon is a bottom-dwelling fish, similar to the stone loach, but with only two whisker-like barbels near its mouth. These sensory organs help it to find its prey in the sand and gravel of the riverbed.

Ynghylch

A small, slender fish, the gudgeon has two moustache-like 'barbels' around its mouth which it uses to detect its prey among the sand and gravel on the riverbed. Found in sandy and gravelly canals, rivers and streams, it is a bottom-feeder, hunting out small invertebrates, such as mayfly larvae and freshwater shrimps, as well as fish eggs. It spawns during spring and summer; the female lays sticky eggs among weeds and stones that hatch out about 10 days after being fertilised.

The Wildlife Trusts work with planners, water companies, landowners, statutory bodies and anglers to help make our waterways and waterbodies as good for wildlife as they are for people. By working together, we can create Living Landscapes: networks of habitats stretching across town and country that allow wildlife to move about freely and people to enjoy the benefits of nature.
