ICES Journal of Marine Science, doi 10.1093/icesjms/fsv056 Exploitable results – Development and test of a lighter mussel dredge Result descriptionA light dredge for mussel farming was tested using two different experimental setups. A standard Dutch dredge was tested against a light dredge using both a twin haul experiment and a single drege experiment. The weight of the sediment retained was 49% less using the light dredge, compared with the Dutch dredge. There was no significant difference of the catch per unit effort (CPUE) of the two gears. However, in the single dredge experiment, the light dredge had a significant increase in the CPUE of 200%. The replacement of a light dredge reduced suspension of sediments and reduced fuel consumption.
