SARF087: Monitoring and Eradiation of Invasive and Non-Native Species in Aquaculture Units

Start Date: 01/02/2012
End Date: 31/07/2013
Main Contractor(s): The Scottish Association for Marine Science
Other Sponsor(s): e.g. Defra


  1. To review existing published guidance on the recognition and eradication of marine invasive and non-native species, with particular relevance to species that could potentially negatively impact the Scottish aquaculture industry.


  1. To make recommendations for the production of new identification material, if deemed necessary by Objective 1.


  1. To recommend how such guidance could be better disseminated throughout the industry.


Over fifty sources of information were reviewed, relating to the recognition of marine INNS, which have the potential to impact on the Scottish aquaculture industry. This was achieved by trawling through published and grey literature via web searches and personal recommendations. The latter included e-mail contact with national and international experts in Australia, New Zealand and the USA. These sources included a wide variety of materials such as; websites, factsheets, posters, diver cards, splash- proof identification guides and a You-Tube video. Only a small proportion  (<5%) of this material was directly aimed at the aquaculture industry, with the majority produced for the general public or for other marine users, such as the recreational boating community. The material that had been specifically produced for the aquaculture industry in Ireland and Wales, however, only contained information on three and four species, respectively, out of the 12 species that were identified as potentially problematic for the Scottish aquaculture industry


The incorporation of codes of practice into current aquaculture guidance was discussed and  the general consensus was that if voluntary, these codes would have to be created by the users  themselves and be highly specific to a certain sector or location to gain ‘buy-in’ from the industry.


This project has provided recommendations for the production and dissemination of guidance material for the monitoring and eradication for INNS. Future work would be to produce this  guidance material, in conjunction with SARF and the aquaculture industry and to work with Marine Scotland Science and the Scottish Government, to ensure that there are no disincentives to reporting the sighting of an INNS on a farm site.


The review of potential eradication/ control measures has demonstrated that many methods are not easily transferable to the Scottish aquaculture industry, through different working practices or behaviour/ physiology of the native stock. It is, therefore, recommended that future work examines the practicalities and effectiveness of using existing measures (and other novel methods) at both fin-and shell fish sites to eradicate INNS. Funding for this work, may be possible through a future EU LIFE+ proposal that is being led by the Countryside Council for Wales
