Effects of hydraulic shellfish dredging on the ecology of a cultivated clam bed. Aquaculture Environment Interactions 3:11-21. The effects of hydraulic shellfish harvesting on the ecology of biological communities and chemistry of benthic sediments were investigated through a series of experiments conducted over a 5-year period from 2009 to 2013. Studies on a variety of different clam beds were undertaken in collaboration with local shellfish harvesters. Sediment samples were collected over the summer and early fall (June to October) and sorted to identify and count benthic organisms and to measure chemical parameters (e.g., pH, oxygen, aragonite saturation state), at the sediment/water interface. Comparisons of dredged to not dredged seafloor found that the effects of season (date of sampling) and location (sediment grain size) exceeded those of shellfish harvesting. Numbers of newly settled bivalves were often higher on recently harvested bottom. Shallow inshore marine communities appear to be highly resilient to disturbance, whether natural or manmade. Shellfish harvesting had only minor impacts on the ecology of seafloor communities and on chemistry of marine sediments.
