“…Chinese ice fish were mainly introduced to the lakes on the Yunnan‐Kweichow Plateau, which is to the east of Tibetan Plateau and achieved success with an area of 430 km 2 (Zhou & Huang, ). However, there is no record of intentional introduction of Chinese ice fish into Yarlung Zangbo River, and this species is more likely to establish self‐sustaining populations in lakes and reservoirs than in rivers (Kang, Deng, Wang, & Zhang, ; Liu, Li, & Xiong, ), therefore, this species received a low AS‐ISK score. This study suggests that Chinese false gudgeon and Amur catfish Silurus asotus are unlikely to be invasive, but juveniles of these two species have been discovered in the Yarlung Zangbo River.…”

The aim of this study was to identify potentially invasive non-native freshwater fishes in the middle reach of the Yarlung Zangbo River, Tibetan Plateau (China), using the Aquatic Species Invasiveness Screening Kit (AS-ISK), as decision-support tool. Based on independent evaluations of 24 non-native freshwater fishes, receiver operating curve analysis identified a threshold score of ≥29 for distinguishing species likely to pose a high risk of becoming invasive from species likely to pose low-to-medium risk (<29) in the risk assessment area. Nine species were categorized as "high risk": goldfish Carassius auratus, topmouth gudgeon Pseudorasbora parva, brook trout Salvelinus fontinalis, Oriental weatherfish (a.k.a. dojo gudgeon) Misgurnus anguillicaudatus, Siberian taimen Hucho taimen, common carp Cyprinus carpio, peled Coregonus peled, western mosquitofish Gambusia affinis, and Chinese rice fish Oryzias sinensis. The three lowest scoring species were Arctic cisco Coregonus autumnalis, Wuchang bream Megalobrama amblycephala, and Chinese ice fishNeosalanx taihuensis, which are unlikely to be invasive because they are unable to complete their life cycle in the risk assessment area. Climate change assessments scores increased or remained the same for warm-water species and decreased for coldwater species. This study was the first application of AS-ISK in western China, and the results suggest that AS-ISK is a useful and valid tool for identifying potentially invasive risk aquatic species in China.

“…Those commercial species introductions were accompanied by unintentional introductions of top-mouth gudgeon (Pseudorasbora parva), and gobies (Rhinogobius giurinus, and Rhinogobius cliffordpopei), which entered into these lakes as contaminants during the introduction of the commercial species (Chen et al, 1998). The second introduction wave occurred from the late 1970s to the late 1980s with the introduction of icefish (Neosalanx tangkahkeii) to compensate for the decline in fishery yield observed in the early seventies (Kang et al, 2015).…”

Aim Introductions of exotic species have globally modified the structure and function of native assemblages and are recognized as one of the major threats to biodiversity. The current patterns, processes and consequences of invasion have been intensively studied globally, but studies reporting the long-term dynamics of invasions over large areas are rare. Here, we measured how the temporal changes in fish assemblage composition in a Chinese highland isolated-lake landscape drive taxonomic dissimilarity and its turnover component over three successive time periods spanning the last 75 years.Location Yun-Gui Plateau, 15 isolated lakes.Methods The Sørensen and Simpson indices were used to quantify changes in taxonomic dissimilarity and its turnover component over 1940-2015. Results We report a decline of taxonomic dissimilarity between lakes through time, mainly due to a decrease in species turnover. Such a homogenization process was due to the combined effects of the invasion of the same non-native species in most lakes and of extirpation of narrow endemic species. The strong decline in species dissimilarity and turnover was triggered by a high historical level of dissimilarity among assemblages. At a regional scale, the combined effect of introductions and extirpations modified the distance decay of taxonomic similarity between lakes. Surprisingly, this beta-diversity gradient is currently no longer supported by biogeographic and evolutionary processes, but by the human-mediated introduction of distinct exotic species in some lakes. Moreover, an extinction debt process was evident as extirpations sometimes occurred many years after the introduction of non-native species.Main conclusions Our study highlights that high historical differentiation of fishes in isolated lakes has turned to homogenization with dramatic loss of endemic species due to intensive introductions. This provides a striking example of human domination over an extended lake landscape and its associated irreparable biodiversity damages on isolated systems historically dominated by narrow endemic species.

“…Icefish has been traditionally exploited in China for commercial harvesting, representing one of the most important sources of income for the export of fishery products to third countries (Huang et al, 2020). Not by chance, (Kang et al, 2015) in order to meet market demands, there have been several attempts to introduce non-native species into lakes or reservoirs in China, not always successfully (Kang et al, 2015). In Europe, icefish has been widely imported as a surrogate of the juvenile forms of Sardina pilcardus and Engraulis echrasiculus and Aphia minuta, species of higher commercial value traditionally consumed in the areas of the Mediterranean basin marketed in Italy under the name of "bianchetto" and "rossetto", respectively (Armani et al, 2011).…”

Microplastics in vacuum packages of frozen and glazed icefish (<em>Neosalanx</em> spp.): A freshwater fish intended for human consumption

et al. 2021

It is widely accepted that human is exposed to microplastics through food consumption, however data occurrence in foodstuffs are still little and basically limited to seafood. In this study, the presence of microplastics was investigated in icefish (Neosalanx spp.) samples sourced from various mass-market retailers in Italy, supplied as frozen, glazed and vacuum-packed product. Icefish is a small freshwater fish widely imported in Europe from China as surrogate of other fish species subjected to commercial restriction, consumed whole after cooking in several culinary preparation. The samples (~10 g of icefish from each of the 40 packs tested) were digested using a solution of 10% potassium hydroxide and filtered through a 5 μm pore-size filter. Filters of the samples were observed under a stereomicroscope and the chemical composition of the items detected were analysed by FTIR spectroscopy. A total of 163 items were counted in 37 (92.5%) samples with a mean value of 0.42±0.28 items/g w.w. Fibers were the most detected morphotype and several plastic polymers, such as polypropylene, polyethylene, polyethylene terephthalate and polystyrene, were identified by FT-IR analysis. As store-bought samples, the sources of microplastics could be substantially related to contamination during food processing. However, an intravital exposure to microplastics present in the surroundings waters cannot be ruled out. More foodstuffs need to be investigated for microplastic presence. In this study, microplastic occurrence was reported in freshwater biota intended for human consumption sampled directly from supermarket contributing to the risk assessment of human exposure to microplastics via food consumption.
