abstract = "Larval dispersal is dependent on multiple physical and biotic factors, and is a key driver of population connectivity. Connectivity is believed to be important in determining how species will cope in a changing climate by allowing species{\textquoteright} ranges to expand or constrict in response to environmental shifts. The Limfjorden in Denmark contains a large mussel fishery from the species Mytilus sp. based on wild populations and mussel farms. It is believed that climate change will produce changes in the species biology that will affect their dispersal and connectivity. In the following study, we address these changes using an individual-based approach. We couple a 3D physical model system with an agent-based model (ABM) in order to answer whether climate change effects on mussel larvae will affect the dispersal and the structure of the connectivity in the Limfjorden. We produced scenarios changing the pelagic larval duration (PLD), spawning time, and larval presence after events of hypoxia. Recruitment and self-recruitment of larvae in the different areas was investigated in depth. The results show no significant difference of the spawning and PLD scenarios except for the lowest PLD. Severe events of hypoxia could potentially lead to isolation of the southeastern areas of the fiord. Overall, this well-connected system is very stable to changes. These results are of fundamental importance for the future management and conservation of the mussel fisheries and wild mussel populations in a changing climate.",
