SeafoodNews reported on February 10 that in order to reduce the use of pesticides and drugs in the breeding area, wrasse (Wrasse) is widely used as a cleaning fish to remove sea lice from salmon in the cage.
Sea cucumbers and sea urchins in Scottish waters belong to the same subject. Now people hope that they can be used to treat uneaten sedimentary food and the precipitation of fish sewage, thereby reducing the pollution of the marine environment.
Scottish scientists initiated this new study, which may change the future development trend of the aquaculture industry.
This method has been verified in Asia and Chile, but its application in the European Union and the United Kingdom is limited.
Blue Remediation was established by a team of doctoral students from the University of Strathclyde and Heriot-Watt University. It has won the UK Seafood Innovation Fund and the Continued Aquaculture Innovation Center (SAIC) support. The experimental part of the project will be carried out in cooperation with the Marine Science Society of Scotland (SAMS) in Eupen, led by Dr. Georgina Robinson, and supported by members of the scientific team.
The initial test is expected to last three months, using 18 Scottish sea cucumbers with different diets to demonstrate the performance of these creatures in a real fish farm environment.
The sediment was collected and provided by the fish farming giant Mowi from its farm in Loch Leven, and the salmon manure was provided by the University of Stirling Aquaculture Research Institute to simulate natural ecosystems.
Sea cucumbers are considered a delicacy in Asia. If research proves that they are effective cleaning animals, the potential for cultivating sea cucumbers is very great.
