Review of allochthonous fish species with the marine origine in Serbian freshwater system
Bibliographic record
Abstract
During the last decades in the freshwater system in Serbia 32 allochthonous fish species appeared, and they can be divided into five groups according to their region of origin: Asian, Ponto-Caspian, North American, South American, and Europe without Ponto-Caspian region. The Asian and Ponto-Caspian species are the most numerous. In the first group are representatives of fish fauna which are originally from Asia and they are intentionally introduced into open waters and aquaculture in Serbia, while the second group represents the migrants spreading their range from the Black Sea into freshwater systems. Some of these species already have established populations. Representatives of marine origin that inhabit freshwater systems in Serbia are: Syngnathus abaster, Neogobius fluviatilis, Neogobius melanostomus, Babka gymnotrachelus, Ponticola kessleri, Proterorhinus semilunaris, Knipowitschia caucasica, Benthophyllus stellatus, Gasterosteus aculeatus, Morone saxatilis x Morone chrysops. Gobiidae and Sygnathidae extended their geographical distribution outside their native range and expanded their area of distribution throughout whole Danube River Basin, while for the other specimens there are no literature data about established populations.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
