Effects of pile driving sound playbacks and cadmium co-exposure on the early life stage development of the Norway lobster, Nephrops norvegicus

  There is an urgent need to understand how organisms respond to multiple, potentially interacting drivers in today’s world. The effects of the pollutants of anthropogenic sound (pile-driving sound playbacks) and waterborne cadmium were investigated across multiple levels of biology in larvae of the Norway lobster, Nephrops norvegicus under controlled laboratory conditions. The combination of pile-driving playbacks (170 dBpk-pk re 1 µPa) and cadmium combined synergistically at concentrations > 9.62 µg[Cd] L-1, resulting in increased larval mortality, with sound playbacks otherwise antagonistic to cadmium toxicity. Significant delays in larval development were caused by exposure to 63.52 µg[Cd] L-1, dropping to 6.48 µg[Cd] L-1 in the presence of piling playbacks. Pre-exposure to piling playbacks and 6.48 µg[Cd] L-1 led to significant differences in swimming behaviour of the first juvenile stage. Biomarker analysis suggested oxidative stress as the mechanism of deleterious effects, with cellular metallothionein (MT) being the predominant protective mechanism.
