A study on dredge efficiency in oyster fishery showed that dredge efficiency is low. In mussel culture dredges are adjusted according to the circumstances. An increase in dredge efficiency will reduces the numbers of tows required to catch the harvest limit, reduces costs, and reduce localized biological and ecological effects. Dredge designs to increase efficiency need to be able to cope with a range substrate compositions and topography, different types and volumes of bycatch, a range of current speeds and sea conditions. We want you to quantify and visualize mussel dredge performance, by means of underwater video cameras. This will result in recommendations, on how to improve dredging efficiency. | ||
