Breaking and entering: Examining the role of stress and aerial exposure in predator-prey relationships between the common shore crab (Carcinus maenas) and cultivated blue mussels (Mytilus edulis)

This work is directly relevant to those involved in the benthic cultivation of mussels. Whilst extensive research has investigated sized-based predator-prey relationships but very little is known about how stress may alter the relationship between Carcinus maenas and Mytilus edulis. Our findings have particular relevance to the on-growing of mussels in benthic cultivation and demonstrate that efforts made during handling and transportation processes to maintain mussel condition do not increase their resilience to predation. This research can be used to inform producers on the impacts of predators on their crop and highlights the continued need to monitor and control them to reduce losses and ensure monetary profit.
