Coastal pathways and connectivity for harmful jellyfish species

A team of scientists from University College Cork led by Chief Scientist Dr. Damien Haberlin carried out a week long survey on-board the RV Celtic Voyager to investigate the seasonal coastal current that circulates in an anti-clockwise direction around the southwest coast of Ireland. This current is known as a pathway for advecting Harmful Algal Blooms (HABs) along the coast, and it is thought this same current could advect harmful jellyfish into the bays of southwest Ireland. These harmful jellyfish species can have major negative impacts on the salmon aquaculture production as they can be swept through the salmon cages and sting the gills of the fish leading to lesions and possible mortality events.
