What the day feels like
What the day feels like
Expect a long, deliberate day on the water: from the pier you head into Blacksod Bay to set lines baited with whole fresh mackerel and to deploy the Rubby Dubby chum mix (mackerel, fish oil and bran). When a shark is hooked the charter team works to photograph, measure and tag before releasing—every trip operates as catch-and-release and contributes data to the Irish Shark Tagging Programme.
