The Romanian Banat E. vladykovi shows greater morphological similarity to E. danfordi than to Romanian “ E. mariae ” (Bănărescu 1969, figs. 19 vs. 17 and 22, derived from original Romanian material), which (if this would reflect their genetic closeness) would suggest the molecular-defined danfordi -like Drava “ E. vladykovi ” population (Pereira et al. 2021).</p><p>Other authors make a case for lumping most or all East European non-predatory Eudontomyzon into a single species, of which E. danfordi is the parasitic “pair species”/form; however, reproductive (in)compatibility was not tested in this case (Popov &amp; Makhrov 2015, Li 2014); at least the Drava “ E. vladykovi ”, given its extreme closeness to E. danfordi (Levin et al. 2016; Bartels et al. 2017; Pereira et al. 2021), may likely prove to be a non-predatory form of E. danfordi .</p><p>CHONDRICHTHYES</p><p>ORD.

Last Romanian commercial capture was in 1956 (Oțel 2007). Nowadays most likely extirpated in the area (Oțel 2007; Jarić et al. 2009; Strat &amp; Gheorghe 2023); see Oțel 2007 for timeline of Romanian catches. Occasional records (latest, 2019) in the middle Danube and its tributaries might indicate the persistence of a population (Nyeste et al. 2020) which could extend to the Romanian Danube above the Iron Gates.

It was, therefore, likely present alongside A. gueldenstaedti in the lower Danube, but unclear whether as a regular, breeding occurence or as a sporadic vagrant; whatever the case, the same conditions that brought about the catastrophic decline of A. gueldenstaedtii must have affected also A. persicus, however, the presence of survivors or recent vagrants is possible.</p><p>The Black Sea form of this species, Acipenser ( persicus) colchicus Marti, 1940 has been treated as a valid species by Kottelat &amp; Freyhof (2007).

Also found in the a tributary of the Prut river in the Republic of Moldova (Volkov et al. 2023); it may also occur in the Prut.</p><p>Bohlen &amp; Ráb (2001) and most subsequent workers considered C. megaspila to be a synonym of C. elongatoides, and the second C. taenia -group Romanian species to be C. tanaitica . Volkov et al. 2023 suggest that a) the Danube Delta C. „ tanaitica ” populations are a distinct species from the north-Pontic C. tanaitica (upon grounds of microsatellite DNA-informed analyses; however, the two clustering versions are not fully congruent, which may furnish a caveat for the validity of this split) and b) C. megaspila Nalbant, 1993 is available for this species as its type material most likely included pure specimens thereof (however, as long as the type material of C. megaspila has not been re-assessed with the same molecular tools as used by Volkov et al. 2023, a caveat still remains as for the availability of C. megaspila). Gynogenetic diploid or triploid hybrids between C. elongatoides and C. megaspila are common across the range of both parental species (Bohlen &amp; Ráb 2001; Janko et al. 2007; Choleva et al. 2008; Choleva et al. 2014; Vasil’ev &amp; Vasil’eva 2022; Volkov et al. 2023). Mezhzherin &amp; Pavlenko 2007 claimed even more diversity for the “lower Danube” Cobitis, including tetraploid hybrids and hybrids having chromosome sets from two alleged undescribed/unidentified species (besides C. elongatoides and C. megaspila [as C. tanaitica]), but this was not confirmed by subsequent research (see references quoted above).</p></div>	https://treatment.plazi.org/id/03DE5C3A0C36CC6D71D8D5EA7BB61336	Public Domain	No known copyright restrictions apply.

Thus, S. balcanica, S. bulgarica and S. vallachica were long seen as subspecies of S. aurata (De Filippi, 1873) which intergrade in some places and allegedly do not intergrade in others (Bănărescu 1964; Bănărescu et al. 1972), then as forms of S. balcanica (Kottelat 1997), and later as distinct species: Nalbant 2003 —even treating the upper MureȘ local form as a species, S. radnensis (Bănărescu et al. 1960), which was not followed by other authors except Bănărescu (2004, 2007); Bănărescu 2004 —attributing Danube-drainage S. balcanica / S. bulgarica to S. montana (Vladykov, 1925), an opinion he later abandoned (Bănărescu 2007); Kottelat &amp; Freyhof 2007. All forms in Romania are variable, encompassing much the same range of variability, and clearly intergrade wherever they meet (Iftime 2002); mtDNA studies have grouped all Romanian forms into a “Danubian-Balkanian complex” (Perdices et al. 2003), more or less structured into lineages defined by drainage catchment/area (Perdices et al. 2003; Bartoňová et al. 2008), such lineages cutting across morphological forms, which are to a large extent ecological (Križek et al. 2020; Fedorčák et al. 2023). However, there is significant discordance between the mtDNA-informed and the nuclear-informed clustering of the “Danubian-Balkanian complex” (Vasil’eva et al. 2022) and its alleged species are not well defined by diagnostic characters (Vasil’eva &amp; Vasil’ev 2023); this, as well the morphological overlap and intergradation, suggest the “Danubian-Balkanian complex” should better be treated as a single species, for which S. balcanica would have priority.</p></div>	https://treatment.plazi.org/id/03DE5C3A0C36CC6C71D8D0D279A717B2	Public Domain	No known copyright restrictions apply.

Bartáková et al. (2019) notice several distinct, mtDNA-defined lineages, of which two (not described, however, as distinct species and apparently intergrading as shown by nuclear DNA data) occur in Romania.</p><p>Fam. Gobionidae</p><p>Gobio gobio (Linnaeus, 1758) (s. l.?)</p><p>A native, widespread freshwater species, found in rivers and sometimes in adjacent stagnant waterbodies, from the plain to the low montane level, in intra- and extra-Carpathian waters (Bănărescu 1964 [as G. gobio obtusirostris]; Bănărescu 1999a [as G. gobio gobio]; Cocan &amp; MireȘan 2018; Nagy et al. 2023). Gobio gobio sensu Bănărescu 1999a was split into several (putative) species (see Kottelat &amp; Freyhof 2007 for their distribution). Of these, the following live in Romania: G. gobio s. str., probably widespread in the extra-Carpathian area, though limited molecular sampling was available (Bulat 2017; Tákacs et al. 2021); a widespread intra-Carpathian form (“ Gobio sp. 1 ” in Tákacs et al. 2021; “ Gobio gobio sensu lato ” in Nagy et al. 2023) which is distinct in a mtDNA-informed molecular analysis and may pertain to G. gobio s. str. or be a distinct putative species (for which muresius Jászfalusi, 1951 may be available) (Tákacs et al. 2021); G. carpathicus Vladykov, 1925, formerly considered to be more widespread in the Carpathian catchment area but limited in Romania (if present at all) to the the Tisza drainage in the MaramureȘ area (Cocan &amp; MireȘan 2018; Tákacs et al. 2021; Polyák et al. 2022; Nagy et al. 2023 [giving the Tisza/ MaramureȘ records under “ Gobio gobio sensu lato ”]); and G. obtusirostris Valenciennes, 1842, from (at least) the CaraȘ, Nera and Cerna drainages in the Banat area (Cocan &amp; MireȘan 2018; Tákacs et al. 2021; Nagy et al. 2023). However, further investigation has shown that the above-mentioned putative Gobio species do hybridize in extensive areas (Zangl et al. 2020). Treating them (or part of them) together as a “continuum”, “ Gobio gobio sensu lato ” (cf. Tákacs et al. 2018; Nagy et al. 2023), likely corresponding to a single biological species, is probably justified as their genetic distance is small, their diagnosis difficult (Tákacs et al. 2022), their mitochondrial and nuclear lineages are quite discrepant (Zangl et al. 2020) and their reproductive isolation is not explored.</p></div>	https://treatment.plazi.org/id/03DE5C3A0C35CC6E71D8D4EE7C2E113E	Public Domain	No known copyright restrictions apply.

Alburnus danubicus s. str. was considered extinct (Freyhof &amp; Kottelat 2007; Kottelat &amp; Freyhof 2007; Cocan &amp; MireȘan 2018; Stefanov, 2019) and A. sarmaticus extremely rare (Oțel 2007; Freyhof &amp; Kottelat 2007; Kottelat &amp; Freyhof 2007; Boltachov 2009; Stefanov &amp; Trickova 2011; Cocan &amp; MireȘan 2018; Stefanov 2019). A sedentary or limited-range potamodromous population was found in the Danube between Tutrakan and Vetren, opposite CălăraȘi county, Romania (Stefanov 2019), and another right below the Porțile de Fier II dam (Bănărescu, pers. comm.); the latter survives as attested by recent catch-and-release records which allowed provisional identification as A. sarmaticus (Szilagyi, F., 2021, via Moraru, M.

Alburnus mento -group shemayas are largely overlapping in diagnostic features (Parin et al. 2014; Halasi‐Kovács 2017), hence the call for treating all those in the Pontic drainage as a single taxon (Parin et al. 2014) despite the possible validity of some Pontic species (Parin et al., 2014). Later, Halasi‐Kovács (2017) argues for the synonymy of A. sarmaticus and A. danubicus, including a neotype designation for the latter, while in parallel Bogutskaya et al. (2017) not only maintain these two species, but describe A. sava as distinct from both; however, Harka &amp; Halasi-Kovács (2024) solve the conundrum by treating the Danubian group as represented by two species ( A. danubicus, which includes A. sarmaticus, and the distinct A. sava) which we follow here, under the caveat of a fluid taxonomy, as molecular and morphological studies show that the diversity of the shemayas might be overestimated (Bektas et al. 2020, Bayçelebi et al. 2021).</p></div>	https://treatment.plazi.org/id/03DE5C3A0C33CC6B71D8D57A7C9B162E	Public Domain	No known copyright restrictions apply.

One isolated record in the MureȘ River (Nalbant 1995) was erroneous (Nalbant, ex verbis). The Comana population was described by Crăciun (1996) (as a sideline upon studying its ethology) as “ Leuciscus borysthenicus ssp. celesticus ”, which was deformed into “ L. celensis ” by MeȘter et al. 2003. Nalbant (2003) commented that Crăciun “described the spawning habits of this species, naming it fortuitously celesticus . Although his action is not completely in accordance with the ICZN rules, it could represent the first description of this species” and accepted it as L. celesticus . While possibly available, celesticus is likely not valid (Bănărescu 2005; Oțel 2007), and certainly not so as a distinct species; the morphological features emphasized by Crăciun (1996) for celesticus are visible in illustrated specimens from other areas: a darker lateral band (Oțel 2007; Kottelat &amp; Freyhof 2007), a bluish sheen (Bulat 2017), and the intensely red eye is also part of the known variation (Kottelat &amp; Freyhof 2007); a molecular phyletic analysis found the Comana population and the Danube Delta one significantly less different from each other than other conspecific populations treated by the same study (Durand et al. 2000).</p></div>	https://treatment.plazi.org/id/03DE5C3A0C31CC6A71D8D5EA794C1482	Public Domain	No known copyright restrictions apply.

It is difficult, given the current data, to ascertain whether this hybridization is introgressive with some selection against the hybrids (as vaguely suggested by the extinction of the “giant” putative hybrids), and therefore the stocks may be distinct species, or intraspecific, with “giant” morphology determined by transient variations in food availability, as argued by Slynko et al. 2018; we follow the latter perspective.</p></div>	https://treatment.plazi.org/id/03DE5C3A0C23CC7B71D8D1FA7D66152A	Public Domain	No known copyright restrictions apply.

Gasterosteidae</p><p>Gasterosteus aculeatus Linnaeus, 1758</p><p>A native euryhaline species, found along all Romanian Black Sea waters, as well as in the Danube Delta, Razim lagoon complex, some littoral lakes and some inner waters (the Danube ca. 100 km upstream; the Siret up to Piscu, Galați county; the Prut). It migrates from the sea to coastal lakes, lagoons, Danube mouths etc., but also includes sedentary lacustrine populations (Băcescu &amp; Mayer 1956; Bănărescu 1964; Oțel 2007; Radu et al. 2008; Yankova et al. 2014; Țoțoiu et al. 2018; Cocan &amp; MireȘan 2018; Niță et al. 2022). Nowadays rare in the sea (Oțel 2007 gives it as absent, but see Țoțoiu et al. 2018, and Niță et al. 2022, who still give it as present in the recent years), and recently not found in the Razim complex (Năstase et al. 2022). There are differences in morphology between the marine populations and some of the lacustrine ones (Băcescu &amp; Mayer 1956; Bănărescu 1964; Denys et al. 2015)—such is the case of Gasterosteus crenobiontus Băcescu et Mayer, 1956, an endemic putative species, previously found in and area of freshwater springs at the inland end of lake Tekirghiol, isolated from the sea (and from marine G. aculeatus) by the hypersaline waters of the lake. Described as a form of G. aculeatus (Băcescu &amp; Mayer 1956), then treated as a subspecies (Bănărescu 1964; Bănărescu 1994) then as a full species (Kottelat 1997; Nalbant 2003; Kottelat &amp; Freyhof 2007; Cocan &amp; MireȘan 2018). However, this population was put in contact with the marine G. aculeatus when the Tekirghiol was freshened by irrigation outflows (presumably, in the 1970s-1980s), and it was merged into the marine-origin, typical-form G. aculeatus by massive crossing, showing biological conspecificity and erasing distinctness (Bănărescu 1994; Bănărescu 2007 [does not mention crenobiontus, but only G. aculeatus]).</p></div>	https://treatment.plazi.org/id/03DE5C3A0C1DCC4071D8D1FA7D6A145E	Public Domain	No known copyright restrictions apply.

Anadromous Lampetra are known from the Black Sea (Kottelat &amp; Freyhof 2007; Naseka &amp; Diripasko, 2008; Li 2014), and, as Lampetra fluviatilis (Linnaeus, 1758) is very similar to, and apparently conspecific with (and senior synonym of), L. planeri (Popov &amp; Makhrov, 2015; see also supporting results in Rüber et al. 2023, though without concluding thus) and Lampetra - Eudontomyzon hybrids are known (Levin et al. 2016), sporadic anadromous L. fluviatilis may hypothetically have generated L. planeri -like hybrids as mentioned above.</p><p>CHONDRICHTHYES</p><p>ORD.

CărăuȘu only mentioned the species for the Black Sea, but given that no other Pontic riverine country claims this record, and the information has emerged that it (probably?) pertains to the Danube Delta area (Aleksandrov et al. 2017) then it must by necessity belong to Romania; still, we cannot consider it otherwise than doubtful.</p><p>ORD.

Oțel (2007) considers its presence doubtful in Romanian waters (as not a single individual could be confirmed). It has disappeared (or at least became extremely rare) in the north-western Black Sea (Mezhzherin &amp; Vernygora, 2013) and was not found even in the Azov Sea, in a recent sample (Vernygora et al., 2018).</p><p>ORD.

Its presence is doubtful since no definite records are known for C. strumicae, a Bulgarian endemic, for the Danube river (which is shared with Romania): Stefanov (2007) considers its presence in the Danube and lower course of Danubian tributaries questionable, and other resources give the range of C. strumicae as not touching the Danube (Vassilev &amp; Pehlivanov, 2005; Choleva et al. 2008; Stefanov 2019).</p><p>Fam.

Romanian records above the Iron Gates (of which there is at least one in the Danube, see Bănărescu 1964, and one in the MureȘ, see Halasi‐Kovács 2017) probably pertain to this species (Bogutskaya et al. 2017; Halasi‐Kovács 2017; Harka &amp; Halasi-Kovács 2024), but this should be checked upon specimens, if available. It survives in the Kolpa river ( Sava river catchment) (Kottelat &amp; Freyhof 2007; Bogutskaya et al. 2017), Danube and Tisza (Halasi‐Kovács 2017; Harka &amp; Halasi-Kovács 2024), but was not recorded recently in or near Romania.</p></div>	https://treatment.plazi.org/id/03DE5C3A0C12CC4B71D8D32E793E1416	Public Domain	No known copyright restrictions apply.

Bănărescu 1964), the central Turkish Black Sea coast near Sinop (Bat et al. 2006) and the Crimea (Karpova et al. 2017; Shaganov &amp; Koulish 2018), none of which currently belongs to Romania (however, Cape Kaliakra did in 1940, when A. m. bacescui was described by Antoniu-Murgoci, hence probably part of the confusion). The 1952-1998 records of Nicolaev et al. 2004 are not substantiated with specimens or images (or references thereof) and therefore difficult to either accept or refute—as in the case of other gobiesocids.</p><p>The Black Sea population of this species is sometimes split as A. bacescui (Murgoci 19404) (e.g. Froese &amp; Pauly 2025) but has been argued to represent at most a subspecies of A. dentatus (Briggs 1986; Karpova et al. 2017; Gus’kov et al. 2022; Fricke et al. 2025).</p><p>4 Which should be in fact Antoniu-Murgoci, 1940 (see Bănărescu 1964).</p><p>ORD. PERCIFORMES</p><p>Fam. Serranidae</p><p>Serranus hepatus (Linnaeus, 1758)</p><p>A native marine species, sporadically (or potentially) found in Romanian Black Sea waters (Yankova et al. 2014; Cocan &amp; MireȘan 2018). The presence is questionable since the actual record(s) referred to by the first quoted source do not pertain to Romania, and the second does not give any record or reference for the species’ Romanian occurrence.</p><p>Fam. Percidae</p><p>Gymnocephalus acerina (Guldenstaedt, 1774)</p><p>A native, widespread rheophilic freshwater species, allegedly recorded in the Prut river (Moshu et al. 2006). The authors do not provide an image or mention depositing a specimen. There is no other record for this species for the Prut (Usatâi 2004; Davideanu, 2008; Ion et al. 2009; Bulat et al. 2013; Bulat et al. 2016; Bulat 2017) or for Romania; it does not occur westwards of the Dniester drainage (Kottelat &amp; Freyhof 2007; Bulat 2017). However, an artificial translocation of this species into the Prut drainage, when stocking other fishes from the Dniester catchment in Moldova, cannot be entirely ruled out; whether it witnessed such an accidental translocation (not resulting in establishment), or is simply a mistake, the record of Moshu et al. 2006 remains doubtful.</p></div>	https://treatment.plazi.org/id/03DE5C3A0C11CC5571D8D4EE7C3315BA	Public Domain	No known copyright restrictions apply.

Indications from fishermen as to the extremely rare presence in the sea of a darker, narrower-snouted pikeperch led Antipa (1909) to suspect that this species may occur (or had occurred) in Romanian waters, though he himself never acquired one. The species is found in the Dniepr-Bug estuary (Roman et al. 2018) and apparently extends to the Bulgarian shores (Vassilev &amp; Pehlivanov 2005); though not listed by Stefanov (2007), it was filmed in Bulgarian marine waters, not far from Romania (Kovtun 2014); therefore it may well reside in or transit the intervening Romanian marine waters, though not a single specimen was yet scientifically recorded.</p><p>ORD. CENTRARCHIFORMES</p><p>Fam. Centrarchidae</p><p>Micropterus dolomieu (Lacepede, 1802)</p><p>A non-native freshwater species, a record of which (from Covasna county) needs to be confirmed (Iftime &amp; Iftime 2021).</p><p>D) unwarranted/erroneous records/citations</p><p>Several more species are included in general distribution maps/species lists for the Romanian Black Sea shore: Chondrichthyes: Ord. Squatiniformes, Fam. Squatinidae: Squatina squatina (Linnaeus, 1758) (Roux 1986); Ord. Myliobatiformes, Fam. Gymnuridae: Gymnura altavela (Linnaeus,1758) (McEachran&amp;Capapé1986);Osteichthyes: Ord. Scombriformes, Fam. Scombridae: Auxis rochei (Risso, 1810) (Froese &amp; Pauly 2025), Euthynnus alletteratus (Rafinesque, 1810) (Froese &amp; Pauly 2025); Ord. Perciformes, Fam. Triglidae: Eutrigla gurnardus (Linnaeus, 1758) (Hureau 1986; Cocan &amp; MireȘan 2018); Ord. Acanthuriformes, Fam. Sciaenidae: Argyrosomus regius (Asso y del Rio, 1801) (Chao 1986; Cocan &amp; MireȘan 2018); Ord. Lophiiformes, Fam. Lophiidae: Lophius budegassa Spinola, 1807 (Caruso 1986); Ord. Tetraodontiformes, Fam. Balistidae: Balistes capriscus Gmelin, 1789 [as B. carolinensis] (Tortonese 1986). None of these is mentioned by any Romanian author (other than Cocan &amp; MireȘan 2018) and all are explicitely stated by Vasil’eva 2007 and Yankova et al. 2014 not to occur in Romanian waters; these are most likely unwarranted extrapolations for presence on the Romanian shore from the fact of known occurrence in the Black Sea. The same is valid for Epinephelus caninus (Valenciennes, 1843) and E. costae (Steindachner, 1878), quoted by Froese &amp; Pauly (2025) as present in Romania, but they are absent from even the Black Sea (Karpova et al. 2019; Karakulak et al. 2025). At present, they cannot be included in the Romanian checklist, though their future record in Romanian waters is by no way impossible.</p><p>Other erroneous records: Ord. Salmoniformes, Fam. Salmonidae: Salvelinus namaycush (Walbaum, 1792) — included by Cocan &amp; MireȘan 2018 on the list of Romanian fishes, quoting Bănărescu 1964, Decei 1981, Manea 1985 and Nalbant 2003, none of which mention this species as being ever introduced to Romania; Cocan &amp; MireȘan 2018 possibly mistake mentions of lake trouts, i.e. the lake morph of Salmo trutta, for Salvelinus namaycush which is also called “lake trout” in North America; Ord. Cypriniformes, Fam. Cobitidae: Sabanejewia aurata (De Filippi, 1863) (Cocan &amp; MireȘan 2018; Froese &amp; Pauly 2025);Fam. Cyprinidae: Barbus cyclolepis Heckel, 1837 (Cocan &amp; MireȘan 2018; Froese &amp; Pauly 2025); Barbus borysthenicus Dybowski, 1862, (Moshu et al. 2006 —as “ Barbus barbus (L., 1758) / Barbus barbus borysthenicus Dybowski, 1862 ”; Bulat et al. 2013); Fam. Leuciscidae: Alburnus chalcoides (Güldenstädt, 1772) (Cocan &amp; MireȘan 2018; Froese &amp; Pauly 2024), at least in some cases, most probably, as a technical artifact or misunderstanding of the taxonomical splitting process (see Kottelat &amp; Freyhof 2007; Movchan 2009; Roman 2015 for these species and their true range); Ord. Carangiformes, Fam. Soleidae: Pegusa lascaris (Risso, 1810) (Cocan &amp; MireȘan 2018; Froese &amp; Pauly 2025)—probably also as an artifact of taxonomical splitting, whereas P. nasuta applies to Pontic populations previously included in P. lascaris (Vasil’eva 2007), though Froese &amp; Pauly (2025) give both species as ranging into the Black Sea; nevertheless, as discussed above, morphological data available for Romanian specimens allow them to be attributed, so far, to P. nasuta alone.</p><p>The total tally of species mentioned for Romania is of 220 species currently or lately having Romanian (reproductive) populations or at least circumstantial indications thereof, or sporadic/expanding into Romanian waters (including four species most probably now extirpated from Romania: Acipenser nudiventris, Acipenser persicus, Acipenser sturio, Thunnus thynnus; other listed species have not been recorded in Romania for a quite long time and may be likewise be extirpated, or merely undetected—see comments above); 32 non-native species which do (did) not independently reproduce/persist, including 2 stocked alien hybrids 5; 20 potentially occurring or doubtfully recorded species; and 16 unwarantedly/erroneously claimed species.</p></div>	https://treatment.plazi.org/id/03DE5C3A0C0ECC5471D8D7667C5914EE	Public Domain	No known copyright restrictions apply.
