26577 Effects of Clam Dredging 2009-2013 Data Set Published / External 23141 Aquaculture Systems & Ecology Branch (ASEB) Project Completed 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.

The organisms are collected using a Smith McIntyre benthic grab which takes a sample of sediment, which is sorted back at the lab to remove all the benthic organisms, which are identified using taxonomic keys and field guides and counted. Field sampling to collect benthic organisms is conducted aboard the R/V Victor Loosanoff. A Smith McIntyre benthic grab is used to collect bottom sediments which are sieved through a 4 mm onto a 1 mm screen, placed in jars, and brought back to the lab for processing. 32740 bivalve counts 2013 Summary Published / External Completed Effects of hydraulic shellfish harvesting on sediment chemistry and bivalve abundance was examined on a leased, cultivated clam bed near Milford, Connecticut in the central basin of Long Island Sound. The clam bed was divided into two 2-ha plots, one was hydraulically dredged by commercial clam boat in January 2013 and one remained not dredged to serve as a control. Both plots were further subdivided into 9 boxes for spatially randomized sampling. Pore-water chemistry and sediment grain size were measured on 3 occasions over the study period from July to October 2013. Four sampling trips to obtain benthic sediment using a Smith McIntyre grab were conducted over the same time interval.
