Fisherman PJ Martyn talks viewers through the changes in the dredging process since he first began fishing in Galway Bay more than 40 years ago. Significant changes in the abundance of shellfish is noted and the recording clearly illustrates the challenges facing the livelihoods of local oyster fishermen and the continuance of this aspect of coastal life in rural Galway. One of the areas that Cuan Beo is actively focusing its efforts on is addressing the continued demise of water quality in the Bay, its impact on sentinel and protected species such as the Native oyster and subsequent effects on the quality of life, environment, economy and heritage around Galway Bay.
