SLU Aqua Sailor is an aquatic unmanned ocean vehicle missioned to survey the sea and collect environmental data used in research and monitoring programmes. The autonomous drone has a wide range of benefits compared to traditional ship-based data collection: it has minimal environmental impact, runs quietly, operates in all weathers and offers a smart and gentle data collection. SLU Aqua Sailor is stationed at the Institute of Marine Research in Lysekil.
SLU Aqua Sailor is used in both research and environmental monitoring and offers a cheap and interference-free method for data survey.
Equipped with specially designed acoustic sensors, the unmanned SLU Aqua Sailor will measure the amount of fish and plankton thanks to new algorithms. The sensors reduce the need for traditional monitoring of fish and provides a more gentle sampling. With SLU Aqua Sailor, information on ocean conditions such as salinity and water temperature, are also measured, and via GPS researchers can continuously keep track of the location of the drone.
The SLU Aqua Sailor drone was built in Norway and was purchased by the Department of Aquatic Resources in the autumn of 2018, with partial funding from the Nordic Council of Ministers. SLU Aqua Sailor is stationed at the Institute of Marine Research in Lysekil.

During the late spring and summer of 2020, 2021 and 2022 the SLU Aqua Sailor drone sailed between the great Swedish islands of Öland and Gotland and collected data on the amount of fish and zooplankton. The drone survey partly took place at the same time as the fisheries survey Sprat Acoustic Survey (Spras). Spras collects information on herring and sprat in the Baltic Sea, and is carried out with the research vessel R/V Svea. By matching data from Spras with data from the sailing drone, the researchers hope to gain better knowledge of how the Baltic Sea ecosystem works.
On its first trip in December 2018, SLU Aqua Sailor sailed over 600 km in the North Sea in the areas around Lilla Middelgrund and Fladen in the Kattegat Sea. Registered data will be used to improve the protection of the Kattegat's unique habitats.
