Hand harvesting, (for instance using hand-pushed rakes, hand-dredge, dip nets, harvesting-knife, or direct manual harvesting) instead of dredging can have fewer negative impacts on subtidal benthic invertebrates and the surrounding seabed (Bishop et al. Dredging, for instance for bivalves, normally involves towing a heavy steel frame along the seabed, which negatively impacts subtidal benthic invertebrates due to direct physical damage, and changes to the seabed structure and topography (Currie & Parry 1996).
