Robson Green has officially opened Hexham Fish Pass.
The Fish Pass is designed to make it easier for salmon and sea trout to migrate upstream to breed.
Tyne Rivers Trust is the driving force behind the project, which has been more than twenty years in the planning.
It was completed last year but officially opened today (22nd March) to coincide with the opening of the brown trout fishing season on the river Tyne.
TV star Robson Green has hit out at tax-dodging celebrities, saying that they should "hang their heads in shame".
The actor and presenter, 49, singled out particular criticism for comedian Jimmy Carr, who previously admitted making a "terrible error of judgment" after his arrangements - he was said to be using an aggressive but legal tax-avoidance scheme - came to light.
Earlier this year, multi-millionaire Take That star Gary Barlow was also accused of being involved in a tax avoidance scheme and later broke his silence to "apologise" on Twitter.
Green, whose father was a miner, told the magazine that he was "very proud" to be a 50% tax-payer.
