Patsy Peril joined Alan Morrissey in-studio to chat about his latest book.

Swimming Upstream: One Man’s Fight to Save the Atlantic Wild Salmon, written with Deirdre Nuttall, details Patsy’s mission to save the Shannon’s wild salmon, which have been affected by Ardnacrusha Power Station.

Patsy knows plenty about fish and fishing, having been born to a small fishing community on the Shannon.
