| Definition | A towed box dredge where the make and manufacturer are unknown. The dredge is a box-shape and extracts fauna by means of a blade that is 41cm deep and 91cm wide. Typically, hydraulic dredges fluidise the sand immediately ahead and then extracts fauna from the substrate using a blade that protrudes into the sediment. The forward movement of the dredge blade through the fluidised sand lifts the biota and backwards into a collecting vessel. | ||
