Пескари (Gobio) относятся к одному из самых широко распространенных в Евразии видов пресноводных костистых рыб. Пескари, наслеюящие водоемы Казахстана, Сибири и бассейна Амура, отличаются от европейских видов, их систематика нуждается в подробном изучении. Эндемичный вид пескаря G.acutipinnatus Men'shikov обитает в озере Маркаколь. Не ясным является таксономический статус пескаря, населяющего бассейн р.Иртыш. В Зайсанской котловине много малых рек, и подавляющее большинство из них почти не изучено. Целью данной работы являлось установление таксономического статуса и оценка состояния пескаря на примере реки Бейыттыбулак Восточного Казахстана. В 2022 г. пескарь являлся одним из массовых видов рыб в реке Бейыттыбулак. В изученной нами выборке рыбы имели типичную для пескарей форму и окраску тела. Пластические признаки варьируют в широких пределах. Внутри выборки особи различаются по положению плавников и их форме, форме головы и относительным размерам различных ее частей. Выборка пескарей из р.Бейыттыбулак представлена разновозрастными и разноразмерными рыбами, поэтому условия существования вполне удовлетворительны для всех стадий жизни этого вида рыб.Ключевые слова: р. Бейыттыбулак, пескарь, показатели, пластические, счетные признаки.

The introduction of freshwater fish species is a leading cause of aquatic biodiversity erosion and can spread parasites to native populations. Hidden diversity evidenced by recent taxonomic revisions can add further complexity to the issue by rendering biological assessment data incomplete. The Eurasian minnows Phoxinus are one such example of cryptic diversity, with several described species being invasive. Current non-native fish populations in the small Mediterranean island of Corsica (France) are the result of successive waves of introductions, including several Phoxinus species. This study aims at determining which Phoxinus species were introduced to Corsica using the cytochrome oxidase subunit I barcoding marker, reconstructing their introduction routes and examining their parasite communities. The study found four species in Corsica: Phoxinus phoxinus and Phoxinus csikii mainly in the northernmost studied drainage basin and Phoxinus dragarum and Phoxinus septimaniae in the Tavignano drainage basin. P. phoxinus and P. csikii were most likely introduced through a live bait wholesaler while P. dragarum and P. septimaniae were probably introduced by recreational anglers bringing their bait from continental France. The molecular study of their Gyrodactylus (Platyhelminthes: Monogenea) parasites with the ITS marker allowed us to hypothesize inter-drainage basin secondary introduction routes for P. phoxinus and P. dragarum. In several sampling sites, Phoxinus minnows had black spot disease caused by encysted metacercariae of Digenea, likely Posthodiplostomum cuticola. These parasites were also found on the brown trout Salmo trutta in a locality where this patrimonial species co-occurs with Phoxinus minnows. Barcoding should be used in fish communities monitoring to help to accurately identify cryptic species.

Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas. Before the rise in interest regarding the diversity of this genus in the past 15 years, studies carried out on their biology and ecology reported their findings for the Eurasian minnow Phoxinus phoxinus Linnaeus, 1758, which was then considered ubiquitous. A parasites checklist for Phoxinus minnows has yet to be published, and the recent progress on the taxonomy of this genus has enabled us to propose a reassignment of parasite records to their proper host. The most thoroughly studied potential species were the North European species Phoxinus sp. 7 sensu Palandačić et al. 2017, Phoxinus isetensis, and P. phoxinus. We were able to highlight a gap in knowledge for numerous species that have received little‐to‐no attention in terms of parasitology. Systematic molecular identification of Phoxinus minnows should be conducted when studying their parasites, as a reliable identification of the host is vital in parasitology research. Future research will certainly reveal a species‐specific composition of the parasitofauna occurring in Phoxinus, especially among widespread parasites such as Gyrodactylus and Diplostomum. Such specificities could even become tools for assessing the introduction routes of Phoxinus species.
