“…On the contrary, the high threshold score of 20.25 reported for the Iberian Peninsula has been attributed to a particularly low proportion of translocated species (18.0% or 16 out of 89: Almeida et al , ), which is also consistent with findings for Turkey (14.29% or 5 out of 35: Tarkan et al , ). The present results contrast FISK calibrations from outside the Mediterranean Region, that is, southern Finland (22.5: Puntila et al , ), England and Wales (18.9: Copp et al , ), and southern Japan (19.8: Onikura et al , ), whereas the similarly low threshold score from Florida of 10.25 was not due to translocations but rather because many of the established, high‐risk fishes in that region are not widely introduced, established or invasive on a broader geographical scale (Lawson et al ., ).…”

The Freshwater Fish Invasiveness Screening Kit (FISK) v2 and Aquatic Species Invasiveness Screening Kit (AS‐ISK) risk identification screening tools were used to assess the invasiveness potential of 24 non‐native (NNS) freshwater fish species in the River Neretva catchment (Bosnia and Herzegovina and Croatia), a risk assessment (RA) area that is an important Mediterranean hotspot for fish endemism. The two assessors assigned similar scores for the invasiveness potential of the NN fishes, and both screening tools successfully distinguished invasive from non‐invasive species. Mean calibrated threshold scores were 10.25 for FISK and 10.00 for AS‐ISK, with the latter increasing to 12.62 when questions that assess the likely impact of predicted future climate conditions on the RA were taken into consideration. These relatively low threshold values are characteristic of areas with an elevated number of translocated species and suggest that NN fishes pose a considerable threat to native species and ecosystems. FISK ranked 50.0–62.6% of the species as being of ‘high risk’ compared with 58.4–59.3% using AS‐ISK. The highest scores (‘very high risk’) were attributed to gibel carp Carassius gibelio (Bloch, 1782) and pikeperch Sander lucioperca (Linnaeus, 1758). The generic screening tool for aquatic species (AS‐ISK) provided similar risk rankings to its predecessor, FISK, as regards invasiveness potential. For this reason, it is likely to be an effective tool for evaluating the potential invasion risk of NNS freshwater fishes for other RA areas in the Balkans. Copyright © 2017 John Wiley & Sons, Ltd.

The Fish Invasiveness Screening Kit (FISK) version 2 was used to assess the invasiveness potential of 40 introduced and translocated freshwater fish species to Croatia and Slovenia. Based on a priori classification of invasiveness, receiver operating characteristic analysis of FISK scores from two independent assessors resulted in a statistically significant calibration threshold of 11.75. This indicated that FISK was able to discriminate reliably between non‐native species likely to pose a high risk of being invasive and those likely to pose a medium or low risk of invasiveness. Seven species were categorised as ‘medium risk’ and the other 33 as ‘high risk’, whereas no species was categorised as ‘low risk’. The two highest scoring species were European catfish Silurus glanis and North African catfish Clarias gariepinus. Mean scores for all species classified a priori as invasive were ranked as ‘high risk’ sensu lato and fell into the ‘moderately high risk’ subcategory. FISK proved to be a valid tool for assessing the risks posed by non‐native fishes in Croatia and Slovenia. For this reason, it can be adopted as a reliable tool for the prevention of new translocations or introductions of potentially invasive species in the risk assessment area, as well as to assist in decisions regarding future management (i.e. monitoring, control and eradication) and conservation strategies.

“…the U.K. (Copp et al, 2009), Japan (Onikura et al, 2011), Australia , and most notably the western extent of the Mediterranean Region, Iberia (Almeida et al, 2013), which has a similar high level of endemism to the Balkans. This lower threshold for the Balkans region is probably due to the elevated number of translocations within countries of this region, in particular to closed, often artificial waters (e.g.…”

“…Perhaps the most popular tool for the pre-screening of non-native freshwater fishes is FISK, the Fish Invasiveness Screening Kit (Copp et al, 2005a(Copp et al, , 2009, which has been applied in a number of risk assessment areas world-wide (Mastitsky et al, 2010;Onikura et al, 2011), encompassing sub-tropical and warm temperate regions such as Brazil and Iberia (Troca & Vieira, 2012;Almeida et al, 2013). Similar to Iberia, the Balkans Region (henceforth, 'the Balkans') represents a remarkable biodiversity hotspot within the wider Mediterranean Region (Blondel & Aronson, 1999;Médail & Quézel, 1999), which comprises the northMediterranean, mid-European and Ponto-Caspian subregions (Bănărescu, 1990).…”

Risk assessment of non-native fishes in the Balkans Region using FISK, the invasiveness screening tool for non-native freshwater fishes

A high level of freshwater fish endemism in the Balkans Region emphasizes the need for non-native species risk assessments to inform management and control measures, with pre-screening tools, such as the Fish Invasiveness Screening Kit (FISK) providing a useful first step. Applied to 43 non-native and translocated freshwater fishes in four Balkan countries, FISK reliably discriminated between invasive and non-invasive species, with a calibration threshold value of 9.5 distinguishing between species of medium and high risk sensu lato of becoming invasive. Twelve of the 43 species were assessed by scientists from two or more Balkan countries, and the remaining 31 species by a single assessor. Using the 9.5 threshold, three species were classed as low risk, 10 as medium risk, and 30 as high risk, with the latter category comprised of 26 moderately high risk, three high risk, and one very high risk species. Confidence levels in the assessments were relatively constant for all species, indicating concordance amongst assessors.
