Evaluation of ecosystem-level effects of bivalve aquaculture activities: Dredge impacts

PARR-2008-QC-09

Description

An upcoming aquaculture activity in Québec (and elsewhere) is the development of soft-shell clam (and related) farming in intertidal or shallow subtidal areas. The impacts from this type of farming are likely to be associated with harvesting as this is done by hydraulic rake. To this end, a study was done in Quebec 2003 to evaluate impacts of this activity and the recovery of the benthic communities under local conditions (sandy sediments in low energy systems), but it has not been published. This project will focus on the analysis, writing, and publishing of the results of the research on the impacts of hydraulic dredge harvesting of soft-shell clams on benthic communities and the recovery of the communities over a 1 year period.
