1. Haemolymph osmoregulation by the shore crab, Carcinus maenas was confirmed over a range of salinities. 2. Na+K+-ATPase and Mg2+-ATPase activities in gill tissue increased with a decrease in salinity. 3. Na+K+-ATPase and Mg2+-ATPase activities were inhibited after exposure to p,p′-DDT. 4. K+ ion levels of the haemolymph remained unchanged, but Na+ ion levels were affected after 7 hr when transferred from 100 to 5% SW after exposure to DDT.

Mussels tolerant to seawater pH's that are projected to occur by 2300 due to ocean acidification.•Exposure to pH 6.50 reduced mussel immune response, yet in the absence of a pathogen.•Subsequent pathogenic challenge led to a reversal of immune suppression at pH 6.50.•Study highlights the importance of undertaking multiple stressor exposures.•Shows a need to consider physiological trade-offs and measure responses functionally
