“…The ranked levels of confidence (1 = low; 2 = medium; 3 = high; 4 = very high) associated with each response in AS‐ISK mirror the confidence rankings that the Intergovernmental Panel on Climate Change recommended (IPCC, ; see also Copp et al, ). Based on the CL allocated to each response for a given species, the confidence factor (CF) is calculated as:

\sum ()(, {CL}_{Q i}) false/ ()(, 4 \times 55) (i = 1, \dots, 55),

where CL Q i is the confidence level for Question i (Q i ), 4 is the maximum achievable value for certainty of confidence in the response (i.e.…”

“…The other six questions require the assessor to predict how future climatic conditions are likely to affect the BRA with respect to risks of introduction, establishment, dispersal and impact, and these comprise the climate change assessment (CCA). In the recently released AS‐ISK v2, which the assessors employed in the current study, the 16 taxonomic groups of aquatic organisms previously accounted for in AS‐ISK v1 (Copp et al, ) have been expanded to a total of 27 following the classification of living organisms by Ruggiero et al ().…”

Invasive non‐native species (NNS) are internationally recognized as posing a serious threat to global biodiversity, economies and human health. The identification of invasive NNS is already established, those that may arrive in the future, their vectors and pathways of introduction and spread, and hotspots of invasion are important for a targeted approach to managing introductions and impacts at local, regional and global scales. The aim of this study was to identify which marine and brackish NNS are already present in marine systems of the northeastern Arabia area (Arabian Gulf and Sea of Oman) and of these which ones are potentially invasive, and which species have a high likelihood of being introduced in the future and negatively affect biodiversity. Overall, 136 NNS were identified, of which 56 are already present in the region and a further 80 were identified as likely to arrive in the future, including fish, tunicates, invertebrates, plants and protists. The Aquatic Species Invasiveness Screening Kit (AS‐ISK) was used to identify the risk of NNS being (or becoming) invasive within the region. Based on the AS‐ISK basic risk assessment (BRA) thresholds, 36 extant and 37 horizon species (53.7% of all species) were identified as high risk. When the impact of climate change on the overall assessment was considered, the combined risk score (BRA+CCA) increased for 38.2% of all species, suggesting higher risk under warmer conditions, including the highest‐risk horizon NNS the green crab Carcinus maenas, and the extant macro‐alga Hypnea musciformis. This is the first horizon‐scanning exercise for NNS in the region, thus providing a vital baseline for future management. The outcome of this study is the prioritization of NNS to inform decision‐making for the targeted monitoring and management in the region to prevent new bio‐invasions and to control existing species, including their potential for spread.

“…Indeed, all three of these risk assessment protocols have by now been enhanced to meet the minimum standards—demonstrating the utility of this approach. Furthermore, at least one further protocol, the Aquatic Species‐Invasiveness Screening Kit (AS‐ISK) has ensured consistency with the minimum standards (Copp et al., ). An additional component was included to provide background information on the species alongside questions on potential socio‐economic impacts and those on ecosystem services.…”

Biological invasions are a threat to biodiversity, society and the economy. There is an urgent need to provide evidence‐based assessments of the risks posed by invasive alien species (IAS) to prioritize action. Risk assessments underpin IAS policies in many ways: informing legislation; providing justification of restrictions in trade or consumer activities; prioritizing surveillance and rapid response. There are benefits to ensuring consistency in content of IAS risk assessments globally, and this can be achieved by providing a framework of minimum standards as a checklist for quality assurance. From a review of existing risk assessment protocols, and with reference to the requirements of the EU Regulation on IAS (1143/2014) and international agreements including the World Trade Organisation, Convention on Biological Diversity and International Plant Protection Convention, coupled with consensus methods, we identified and agreed upon 14 minimum standards (attributes) a risk‐assessment scheme should include. The agreed minimum standards were as follows: (1) basic species description; (2) likelihood of invasion; (3) distribution, spread and impacts; (4) assessment of introduction pathways; (5) assessment of impacts on biodiversity and ecosystems; (6) Assessment of impact on ecosystem services; (7) assessment of socio‐economic impacts; (8) consideration of status (threatened or protected) of species or habitat under threat; (9) assessment of effects of future climate change; (10) completion possible even when there is a lack of information; (11) documents information sources; (12) provides a summary in a consistent and interpretable form; (13) includes uncertainty; (14) includes quality assurance. In deriving these minimum standards, gaps in knowledge required for completing risk assessments and the scope of existing risk assessment protocols were revealed, most notably in relation to assessing benefits, socio‐economic impacts and impacts on ecosystem services but also inclusion of consideration of climate change. Policy implications. We provide a checklist of components that should be within invasive alien species risk assessments and recommendations to develop risk assessments to meet these proposed minimum standards. Although inspired by implementation of the European Union Regulation on invasive alien species, and as such developed specifically within a European context, the derived framework and minimum standards could be applied globally.

“…Assessments using ENSARS begin with the Pre‐screening module (Copp, Russell, et al, ), which originally comprised a suite of taxon‐specific toolkits and a generic screening module. Since ENSARS’ creation, the generic screening module was combined with the architecture of version 2 (Lawson, Vilizzi, Hill, Hardin, & Copp, ) of the Fish Invasiveness Screening Kit (FISK: Copp et al, ; Vilizzi et al, ) to create the Aquatic Species Invasiveness Screening Kit (AS‐ISK: Copp, Vilizzi, et al, ). The schemes upon which ENSARS was based (cited here above) have been slightly modified, and the AS‐ISK was developed, to comply with the “minimum standards” (Roy et al, ) for evaluating NN species risks under Council Regulation No 1143/2014 on the prevention and management of alien invasive species (EU, ).…”

The European Non‐native Species in Aquaculture Risk Analysis Scheme (ENSARS) was used to assess one of the most popular aquaculture species in the world, the striped catfish Pangasianodon hypophthalmus (Sauvage, 1878), in two locations of southern Anatolia (Turkey). The overall mean risk score generated for P. hypophthalmus by the ENSARS Organism module (which assesses the risks of introduction, establishment, dispersal and impact) indicated that the species poses a medium risk under current climatic conditions. All other ENSARS modules rendered scores that indicated a moderately low risk under current climatic conditions. However, the risks of introducing novel diseases and the actual use (e.g. deliberate introduction to the natural habitats or food market) of the species both attracted scores indicating a medium risk. Confidence levels were medium or high for all modules except the Socio‐economic, with low confidence values also attributed to the risks for farming process of the organism, and its overall risk of spread into the wild during farming procedures and to marketing impacts. Recommendations are provided for further use of the ENSARS scheme, especially for a a priori assessment of potential aquaculture species in Turkey, where the sector has been remarkably developing in the last decades.
