There is limited understanding of how fishing intensity affects the degree to which marine benthic communities are affected by fishing. To address this question, before-after-regressor-impact experiments incorporating 16 scallop dredging intensities were performed in soft and hard substrate communities. Few significant short-term fishing intensity effects were detected in individual taxa analyses in either ecosystem. Results from meta-analyses of individual taxa responses from this study and community-level analyses were consistent with fishing intensity but not general effects of fishing. Therefore, changes unrelated to fishing intensity were interpreted as ecosystem changes unrelated to fishing. The observed number of significant results were similar or lower to the predicted probability of significant results from simulations of power for low fishing effects. Predicted set-specific mortality rates applied to estimated fishing trip and dominant fishing ground-level fishing intensities should lead to low levels of mortality for the taxa included in the analyses.
