[Removing the text below. Getting an image of the total area fished in a single year (the 5%). A couple of sentances about the image and a link to a report using the data.]
In Denmark all vessels fishing for common mussels (Mytilus edulis) are required to be fitted with a sensor system. The fishery involves around 51 dredge vessels with an annual catch of around 30,000 tonnes. The BlackBox R2 system has been installed in the fishery since April 2012 with full functionality and reliability. The system is designed to meet the fishery objective to monitor where and when fishing is taking place, in detail, because mussel fishing is mainly conducted in sensitive marine areas with only 5% of the fishery area fished in a given year.
Data is recorded every 10 seconds. In this fishery data is downloaded in near real time through the GSM network. Due to the frequency and accuracy of the data gathered via our system additional analysis of the data gathered has also been performed by the Danish National Institute of Aquatic Resources (DTU Aqua) to quantify the total area within the Limfjord region that has been directly effected by the mussel fishing operations, which provide valuable information regarding the overall management of the fishery.
