Llyn Crafnant, Conwy
Deep, moody, and very cold. Way way too early in the year.
Rare fish on verge of extinction sets up new home in Conwy Valley - North Wales News - News - Daily Post North Wales
A BACK-UP population of a rare fish under threat of extinction has been released into a North Wales lake.
About 800 young arctic charr, a species which can only be found in a few deep, cold lakes across the region, are now swimming in Llyn Crafnant in the Conwy Valley, thanks to Environment Agency Wales.
The charr released into Llyn Crafnant were hatched and raised from eggs collected at Llyn Padarn in December last year. They have been cared for at the Mawddach Hatchery, near Dolgellau, for the past 11 months.
Mr Edwell has thanked estate managers Carter Jones, lake owners Crafnant Trust and fishery owners Anne and Joe Collins for offering the baby charr a new home.
