Fish species (invasive)

Partnership: Romanian Ministry of Environment, Water and Forests; University of Bucharest The overall objective is to create scientific and administrative tools to efficiently manage invasive alien species in Romania, according to REGULATION (EU) 1143/2014 on the prevention and management of the introduction and spread of invasive alien species

プロジェクトに携わる要員:

We collected occurrence data from various sources published between 1920 and 2022, namely, scientific and grey literature, social media, public databases, online questionnaires, and our field data, most of which was collected during 2019-2022 in the frame of a national survey project (Ministry of Environment and University of Bucharest 2023). Data from the literature were extracted from peer-reviewed articles, conference articles, books, grey literature, doctoral theses, and technical reports concerning the occurrence and distribution of alien fish in Romania. We performed a comprehensive search of literature mentioning alien fish in Romania based mostly on informal searches of papers collected over the years and contacts with experts in the field. In addition, we searched Google Scholar and Web of Science All Databases collection, using a combination of keywords: alien fish, allochthonous fish, invasive fish, dispersal, distribution, new fish, nonnative fish, non-native fish, AND Danube, Danube Delta, Balkans, Bulgaria, Hungary, Moldavia, Romania, Serbia, Ukraine. We used the names of neighbouring countries as keywords because of the presence of shared rivers, such as The Danube River, which is shared with Bulgaria and Serbia. The reference lists of the publications identified this way were further screened for other potentially relevant articles not covered by the search engines used. Data on alien fish occurrences were also downloaded from the Global Biodiversity Information Facility (GBIF), a validated public online database (https://www.gbif.org/). Additionally, we collected data from social networking platforms such as Facebook, where anglers and other fish-related peers submitted reports regarding these species, and an online survey sent to researchers from different Romanian institutions. Occurrence records are structured in a database that contains the following attributes: ID, Species, Source, Year of recording, Latitude, Longitude, Toponym, and Habitat. The occurrence database is limited to invasive alien fish species in Romania since the majority of the remaining alien fish species have very few occurrence records.

Method step description:

1. Distribution data analysis involved the process of standardising and geo-referencing the occurrence reports of invasive alien fish species to enable spatial representation. We plotted the occurrence records using a 10 ⨯ 10 km grid. We overlaid the 11 river management areas according to the Romanian Waters Authority (i.e., Crisuri, Somes-Tisa, Siret, Prut, Dobrogea-Litoral, Ialomita-Buzau, Arges-Vedea, Olt, Jiu, Banat, Mures) onto the grid map of Romania to conduct the analysis at the catchment level.
