The role of wind in controlling the connectivity of blue mussels (Mytilus edulis L.) populations
Summary
Researchers found that wind-driven ocean currents play a key role in determining where blue mussel larvae drift and settle in the Irish Sea, with implications for managing shellfish populations as climate patterns shift. This understanding of surface current dynamics also applies to predicting the movement and accumulation of microplastics in coastal marine environments.
Dispersal of mussel larvae in the tidally energetic Irish Sea during the April-May spawning season is potentially driven by wind-driven surface currents, as confirmed by fisherman observations of inter-annual variability in wild spat collection. These results have important implications for metapopulation dynamics within the context of climate change and sustainable shellfisheries management (i.e. gain and loss of populations and harvest areas according to wind conditions).
