Minnow
The minnow Phoxinus phoxinus is a small freshwater fish (8 to 10cm long) of the carp family. Common throughout much of Eurasia, the minnow prefers cool (12–20 C) streams and well-oxygenated lakes and ponds.

Atlantic Salmon
The Atlantic salmon, Salmo salar, spends most of its life in freshwater where the eggs are laid and juveniles mature, being known initially as parr and later as smolt, migrating to the sea to feed and grow, before returning to spawn in streams and rivers.

White-clawed Crayfish
The white-clawed or the Atlantic stream crayfish Austropotomobius pallipes. is is one of the largest freshwater invertebrates in the UK.

River Lamprey
The river lamprey or lampern,Lampetra fluviatilis, is a primative jawless fish. It is found in coastal waters around almost all of Europe. It feeds as a parasite by attaching itself to the side of another fish and rasping with its sucker mouth. The reproductive cycle is similar to that of salmon. River lampreys migrate upstream from the sea in autumn or winter. Spawning activity is greatest in the springtime and young river lampreys spend several years in soft sediments in their natal rivers and streams before migrating to sea as adults.

Blue-winged Olive Mayfly larva
Mayflies are relatives of the dragonflies and damselflies. They are aquatic insects whose immature stage (called "naiad" or, colloquially, "nymph") lives for a year or more in freshwater.

Brown Trout
The brown trout Salmo trutta is a relative of the salmon. There are both purely freshwater populations and a sea going form known as the sea trout. The latter migrates to the oceans for much of its life and returns to freshwater only to spawn.
