The results of the second year's study tracking salmon and sea trout migration through the Tees Barrage has confirmed anglers' long-held belief that the barrage is a major factor hindering the recovery of migratory fish stocks in the River Tees, which are lagging far behind those in the neighbouring Rivers Tyne and Wear.
Of 72 fish electronically-tagged in the estuary, not a single one successfully negotiated the barrage to migrate up river to spawn.
