"The study, conducted in the fall of 2002, examined a number of health, behavioural, and reproductive variables before, during, and after, seismic shooting in a preliminary attempt to assess potential effects on physical, biochemical, or activity patterns in the subject animals."--Page vi, Executive summary. This study investigated the effects of seismic air gun noise on snow crab and snow crab catches. This was a preliminary attempt to assess the effects of seismic air gun noise on the physical, biochemical, and activity patterns of snow crab. It examined a number of health, behavioural, and reproductive variables before, during, and after seismic shooting. The study found that the noise had no obvious effects on crab behaviour and no significant effects on the health of adult crabs. (Résumé en français.)
