The river bed is home to marine worms, bivalves and larvae. These are fed on by fish, flounders, mullet and eels, which in turn are eaten by cormorant, herons and seals.
The Weir construction allows migratory salmon, sea trout and elvers (young eels) to continue upstream.
Improvements in water quality in recent years enabled the return of salmon and sea trout. Recently even schools of porpoise visited the river at this location. Other notable sightings include otters, mink and seals.
All Salmon, Sea Trout and Eels that migrate up and down the system pass the Weir. Salmon and Sea Trout return to the river, as adult fish, to spawn in the upper reaches. Eels migrate down to the sea, as adults, on their journey to their spawning grounds in the Sargasso Sea.
The Atlantic Salmon has over the last 30 years, re-colonised of the Clyde catchment in increasing numbers, due to improvements in water quality and the environmental management work.
Whilst stocks in northern Europe and North America are cause for international concern, in the Clyde catchment there has been an increase in numbers being reported.
Most river habitats are used but salmon require clean headwater streams with suitable grades of gravel bed for successful spawning which takes place in mainly in the autumn and early winter.
Perhaps the most surprising aspects of the Weir are the numbers of fish species living in the river.
- Up Stream
- Salmon. Sea Trout, Brown Trout, Eels, Roach, Brook Lamprey. Minnow and Stickle Backs
- Down Stream
- Salmon.Sea Trout, Flounders, Mullet, Sea Lamprey and Silver Eels
Many birds species live all year at the river, some stop to rest and feed on their migration routes. Summer months see the passage of martins and terns with goosanders seen from the autumn to spring.
Glasgow City Council has in place an environmental strategy and a wildlife and nature conservation policy. Recently it has agreed to support the production of a local biodiversity action plan for this area. Further information
