“…Remarkably, most methods did not support separation of such traditional fish morphospecies as Leuciscus leuciscus and L. idus (see initial identifications of the sequences from GenBank and BOLD in our tree, Figure 2). Most methods did not support a separation of several taxa within Esox lucius and Rutilus rutilus, in contrast to the opinions of some recent investigators [115,116]. Finally, within the genus Coregonus we observed low genetic differentiation [117] between traditionally separated [118] species, such as European (C. albula) and Siberian (C. sardinella) vendace.…”

To date, a rather large set of both mathematical theories for species delimitation, based on single-locus genetic data, and their implementations as software products, has been accumulated. Comparison of the efficiencies of different delineation methods in the task of accumulating and analyzing data with reference to different taxa in different regions, is vital. The aim of this study was to compare the efficiency of fifteen single-locus species delimitation methods using the example of a fish species found in a single lake in European Russia (Lake Plescheyevo) with reference to other sequences of revealed taxa deposited in international databases. We analyzed 186 original COI sequences belonging to 24 haplotypes, and 101 other sequences previously deposited in GenBank and BOLD. Comparison of all 15 alternative taxonomies demonstrated that all methods adequately separate only the genera, while the number of delimited mOTUs differed from 16 (locMin) to 43 (HwM/CoMa). We can assume that the effectiveness of each method is correlated with the number of matches based on Ctax and MatchRatio criteria. The most comparable results were provided by bGMYC, mPTP, STACEY, KoT and ASAP and the most synchronous results were obtained from bGMYC, mPTP, STACEY and ASAP. We believe that these results are maximally realistic in the number of revealed mOTUs. A high genetic diversity, resulting in the existence of several mOTUs and phylogenetic lineages within many species, demonstrates the usefulness of the “polymorphic species” concept, which does not underestimate species richness and does not prevent the rational use and protection of biodiversity.

“…Nevertheless, only a few species live solely in brackish water environments. Instead, these waters are commonly inhabited by a mix of freshwater, marine, and anadromous (Table 1) taxa and are typically dominated by a low number of species, often of marine origin (Beaudreau et al, 2022; Cabrera‐Páez et al, 2021; Dyldin et al, 2020; Thiel et al, 2003; Whitfield, 1999). The abundance and diversity of marine species tend to increase, and those of freshwater species to decrease, along gradients of increasing salinity (Guo et al, 2022; Kindong et al, 2020; Morin et al, 1992; Thiel et al, 1995; Whitfield, 1999).…”

Brackish water ecosystems often have high primary production, intermediate salinities, and fluctuating physical conditions and therefore provide challenging environments for many of their inhabitants. This is especially true of the Baltic Sea, which is a large body of brackish water under strong anthropogenic influence. One freshwater species that is able to cope under these conditions in the northern Baltic Sea is the vendace (Coregonus albula), a small salmonid fish. Here, we review the current knowledge of its ecology and fishery in this brackish water environment. The literature shows that, by competing for resources with other planktivores and being an important prey for a range of larger species, C. albula plays a notable role in the northern Baltic Sea ecosystem. It also sustains significant fisheries in the coastal waters of Sweden and Finland. We identify the need to better understand these C. albula populations in terms of the predator–prey interactions, distributions of anadromous and sea spawning populations and other putative (eco)morphs, extent of gene exchange between the populations, and effects of climate change on their future. In this regard, we recommend strengthening C. albula‐related research and management efforts by improved collaboration and coordination between research institutions, other governmental agencies, and fishers, as well as by harmonization of fishery policies across national borders.

Fossil taxa of Esocidae include †Novumbra oregonensis from the in Oregon(Cavender 1969;Woodburne 2004), several species of Esox (M. V. H. Wilson 1980; L.

Phylogenetic Classification of Living and Fossil Ray-Finned Fishes (Actinopterygii)

Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the designation of taxonomic groups on the basis of morphological similarity. Starting in the late 1960s morphological phylogenetics became the basis for the classification of Actinopterygii but failed to resolve many relationships, particularly among lineages within the hyperdiverse Percomorpha. The introduction of molecular phylogenetics led to a dramatic reconfiguration of actinopterygian phylogeny. Refined phylogenetic resolution afforded by molecular studies revealed an uneven diversity among actinopterygian lineages, resulting in a proliferation of redundant group names in Linnean-ranked classifications. Here we provide an unranked phylogenetic classification for actinopterygian fishes based on a summary phylogeny of 830 lineages of rayfinned fishes that includes all currently recognized actinopterygian taxonomic families and 287 fossil taxa. We provide phylogenetic definitions for 90 clade names and review seven previously defined names. For each of the 97 clade names, we review the etymology of the clade name, clade species diversity and constituent lineages, clade diagnostic morphological apomorphies, review synonyms, and provide a discussion of the clade's nomenclatural and systematic history. The new classification is free of redundant group names and includes only one new name among the 97 clade names we review and describe, yielding a comprehensive classification that is based explicitly on the phylogeny of ray-finned fishes that has emerged in the 21st century and rests on the foundation of the previous 200 years of research on the systematics of ray-finned fishes.
