As part of a programme to evaluate the potential impact of fishing activities on benthic systems, a short-term field study was conducted to document the changes that occur in benthic habitats and communities resulting from the activities of commercial flounder draggers. The study was carried out within the intertidal zone of the Minas Basin, Bay of Fundy to take advantage of the ability to sample and make observations within the intertidal during the long exposure times that characterize this macrotidal system. The results suggest that the impact, as measured by changes in chlorophyll a and benthic macrofauna biomass, is relatively minor. This may, however, be partly a reflection of the time the study was performed (late fall), and it is recommended that a similar study be carried out during the spring and summer when biological activity and the potential for impacts within the intertidal is greater.
