Thornback Ray Fishing in Ireland

Description

For those chasing a classic Irish thornback ray, focusing on boat fishing in County Clare, Donegal, or Cork offers the most consistent results. The months of June through September represent the prime window for connecting with these powerful fighters. Anglers can expect typical weights around 11lb (4.99kg), with the best specimens reaching up to 14lb (6.35kg). Shannon Estuary and Tralee Bay are standout venues for putting fish on the deck. While a variety of baits work, rag, mackerel, and sandeel remain highly effective choices for these bottom-feeders. Ensure you are well-equipped with reliable tackle, as they provide a dogged resistance when pulled from the seabed. Make sure your hook-bait is fresh, as thornbacks are keen hunters that track down pungent, oily mackerel strips with ease.
