Assessment of the Multispecies Freshwater Biomonitor (MFB) in a marine context: the Green crab (Carcinus maenas) as an early warning indicator.

The Multispecies Freshwater Biomonitor is an online continuous biomonitor which utilises impedance conversion to quantitatively record behavioural responses of vertebrates and invertebrates to environmental change. Here, we extend the use of the MFB into the marine aquaculture environment using the Green crab (Carcinus maenas) as a biological monitor. As a ubiquitous and abundant species, C.
