正文(英文) | News story Salmon found in River Don at SheffieldAn adult salmon has been found in the River Don at Salmon Pastures confirming the species’ return to Sheffield city centre after an absence of 150 years. The body of the 79cm (31 inches) salmon was reported to the Environment Agency by a member of the public on Wednesday 2 January. It appears to have died from natural causes. Coincidentally, January marked the beginning of the International Year of the Salmon, an initiative to support the conservation and restoration of wild salmon species. Following the recent push to improve water quality and introduce more fish passes to facilitate the migration of our native fish, the re-colonisation of salmon in the Don is now becoming a reality. The Environment Agency’s partnerships with the Don Catchment River Trust, Yorkshire Water, Canal and River Trust and Sheffield City Council has introduced multiple new fish passes. These allow fish to move along the river, easing their migration past weirs. The route is only two weirs away from a ‘fish highway’ between the sea and salmon spawning grounds. The penultimate pass, at Sanderson’s Weir, is expected to be completed within the next year. Jerome Masters Environment Agency Fisheries Technical Specialist said:
Examination by Environment Agency fisheries specialists confirmed the female fish had recently spawned. Salmon often die after spawning, consequently, there is no reason to suspect anything other than a natural cause of death. Prior to spawning, the fish probably weighed between 10 to 12 lbs (4.5 to 5.5 kg). Growth patterns in the scales showed the salmon spent two years in freshwater before spending two years at sea. Most salmon return home to the river where they were born, but some will stray up the ‘wrong’ river. This is how they can recolonise rivers where they may have become locally extinct, such as the River Don. Ben Gillespie, Yorkshire Water’s lead environmental advisor said:
