First Finding

Since publication of the previous list (Litvinov & Podolyako, 2013), new data on species composition of fish fauna in the Astrakhan State Reserve have been obtained. As a result of revisions of the collected material and new records (e.g., the first finding of Khvalyn spined loach Cobitis amphilekta Vasil’eva, Vasil’ev, 2012), the list of fish species has been corrected and widened. At present, the list of fish species in the Reserve includes one species of Petromyzontidae and 60 species of Acipenseridae, Clupeidae, Cyprinidae, Cobitidae, Siluridae, Coregonidae, Salmonidae, Esocidae, Lotidae, Atherinidae, Gasterosteidae, Syngnathidae, Percidae, and Gobiidae. Identifications used in previous lists of fishes found in the Astrakhan reserve in 1936–2016 and brief information on biology and dates of latest records of each species are given.

The article provides the results of studying the fish fauna of the Bastak reserve. Based on the analysis of field ichthyologic collections in 2001-2019, the author described the species composition, distribution and habitat specificity in the nature reserve reservoirs - of the fish from the Cobitidae and Balitoridae families. Within the reserve and its conservation zone, it was found the habitat of four representatives of the family Cobitidae and two fish from the family Balitoridae. The research, made in 2019, first discovered the Paramisgurnus dabrianus (Dabry de Thiersant, 1872) and the round-tailed form of Barbatula toni (Dybowski, 1869) in the territory and protection zone of the Bastak nature reserve. There, it was also found some new habitats of species belonging to the families.

Creation of reservoirs by regulation of the Dnieper River and small rivers caused significant changes in the conditions of existence and affected on  fish biodiversity of pondsof Prydniprovya. To the anthropogenic factors influencing the species composition of fish fauna factors of technical and fishery character can be included. Technical impact on water bodies is associated with the creation of new artificial lakes, ecosystems of which are not stable and are influenced by invasive processes. Fisheries management measures include work on the introduction of new species of fish that primarily have economic importance for the development of industrial fishing. Work on the introduction of new species have both positive and negative effects, but nevertheless new species affect natively on fish fauna. This transforms biota of reservoir and creates conditions for further spread of new species, increasing their numbers, creating new ecological relationships in the ecosystem of the pond. In the formation of the Dnieper (Zaporizhia) reservoir`s fish fauna it is traditionally defined five stages: the first stage is before building a dam to the Dnieper (until 1931) when there was a natural Dnieper rapids area, inhabited by migratory, semi-migratory and local fish; the second stage is the beginning of formation of reservoir`s fish fauna with the gradual disappearance of reophilic and dominance of limnophilic species (1931–1941); the third stage is the restoration of fish populations of Dnieper rapids due to destruction of dam during the Second World War (1941–1947); fourth stage is the secondary formation of ichtiocenosis of reservoir after recovery of dam (1947–1960); fifth stage is reforming of the structure of fish fauna in terms of cascade (creation of Dnieper reservoirs) and anthropogenic pressures (from 1961 to the present period). The first stage is defined by period of filling the reservoir. After the construction of Zaporozhye hydroelectric station the process of rebuilding fish fauna took place. In the early years of the reservoir existence migratory and semi-migratory fish have naturally disappeared. The species composition of fish fauna has decreased by 11 taxons. The number of reophilic species has markedly reduced and remained predominantly in the upper river part of the reservoir. The lower part of reservoir with sustained hydrological regime has been being actively assimilated by fish of limnophilic complex. The second and third stages are associated with the destruction of the dam during the Second World War and the short restoration of hydrobiological regime of Dnieper rapids, until the re-filling of the reservoir and its final transformation into a regulated pond. The flow of these two phases has not influenced significantly the structure of industrial ichtyocomplex total number of species at that time was 38 taxons. The fourth stage involves fishery exploitation of reservoir. With the aim of the purposeful impact on formation of industrial fish fauna of the Dnieper (Zaporizhia) reservoir, considering sufficient development of natural fodder the works on artificial introduction of new species were carried out in the years 1950-1960. The fifth stage of development and current state of fish fauna of reservoir is characterized by the emergence and spread of invasive species. During the period of existence of the Dnieper (Zaporizhia) reservoir ichthyofauna of the reservoir has substantially transformed. In the modern fish fauna of reservoir there are 52 species of fish which are representatives of 14 families. Compared with the period of existence of Dnieper River before its regulation the number of species remained at the same level, but the species composition and structure of fish fauna changed drastically due to the loss of some species and the emergence of other species, mostly unwanted invaders. Changing the number of species is related to several factors. Firstly, process of spread of species upstream took place after the disappearance of Dnieper Rapids and rise of mineralization. Secondly, with the deliberate introduction of fish with purpose of fishery exploitation of the reservoir, and as a consequence randomly invasion of some species that came from fish farms. Thirdly, emergence of new species is also connected with the deliberate release of fish to the open water, similarly Pumpkinseed Sunfish Lepomis gibbosus (Linnaeus, 1758) has appeared in the Dnipro (Zaporizhia) reservoir, which is well acclimatized and has broadly extended its habitat in reservoirs of Dnipropetrovsk region. Today about 31 % of fish species of Dnieper (Zaporizhia) reservoir is adventitious. The process of genesis of fish fauna of the Dnieper (Zaporizhia) reservoir is still ongoing and it is connected with the subsequent emergence of new species and rise of their numbers. Such changes in the fish fauna of reservoir can harm fisheries because the vast majority of fish aliens are competitors by food for young commercially valuable fish species.

A total of 48 species of fish fauna were identified during the present study period. The dominant species of fish were found under order Perciformes in all study areas. The most species composition (40) was recorded in Setse fish landing area. The commercially important fish species were mostly found in Kyaikkhami area. Moreover, 17 species of fish were exported to other regions and foreign countries. Among the fish species, species such as Threadfin (Polynemidae), Croaker (Sciaenidae), Hilsa (Clupeidae), Bombay duck (Harpadontidae), Anchovy (Engraulidae), and Pomfret fish (Stomateidae) were the most economically important species. Bombay duck and Anchovy (especially Coilia dussumieri) were more abundant (70%) at the present study sites. Harpodon nehereus and Coilia species were the leading food employed as fresh and dried for local people in the present study areas.

Salado River

The Pampa Plain, in the central region of Argentina, is mostly drained by the Salado River. The fish fauna of this river is mostly known from field collections in lower reach lakes. Consequently, we aimed to explore the composition and structure of the fish assemblages in the upper Salado River lakes. Patterns in dominance and persistence of species and assemblage level attributes were correlated with environmental and human activity-derived (NO3:NH4) variables. Overall, 19,913 individuals of 17 species included in 5 orders and 11 families were collected. Several species are first records for the upper Salado River lakes. There was a marked proliferation of species in the family Characidae. Conversely, the remainder 10 families were only represented by one or two species. The species composition along the study lakes changed slightly but their relative contribution to the total fish collected (dominance) varied greatly. Rather few species were present in all collections suggesting an important interannual variability in assemblage stability. The gradient in water conductivity was an important factor for the persistence of particular species in the lakes. The gradients in water conductivity and NO3:NH4 ratio were associated with particular fish communities dominated by different groups of species. These results suggest that even when broad management and conservation strategies should encompass the system as a whole, lake-specific approaches must also be addressed. Overall, our results highlight that human impacts on surface waters may interact with environmental factors to influence the dynamics of fish species and the structure of their communities.

The ichthyofauna of the headwaters of the main tributaries of the mighty Solimões/Amazonas River  has been little studied. Considering the importance of those environments for the overall fish  diversity in that river system, we surveyed the composition of the fish fauna of the upper portion  of Purus River and two of its tributaries (Caeté and Macapá rivers), state of Acre, Brazil. The collections were done in November 2004, using a seine net and a set of gillnets of different mesh  sizes. A total of 735 specimens belonging to 86 species and 28 families were collected. Eight  species, Creagrutus occidaneus, Phenacogaster pectinatus, Prionobrama filigera, Moenkhausia cf.  lepidura, Leptagoniates pi (Characidade), Henonemus punctatus (Trichomycteridae), Toracocharax  stellatus (Gateropelecidae), and Eigenmannia macrops (Sternopygidae) composed nearly half of the  specimens collected. This survey adds 48 new records to the ichthyofauna of Purus River and  elevates to 243 the number of known fish species in that river, but a greater sampling effort is necessary to produce a reasonably complete picture of the fish diversity in the basin.

Although Chiapas is recognized as home to some of the most interesting fishes in Mexico, there are still regions of the state that are poorly surveyed. Our objective was to document the fish species in La Venta River, as well as that of some of its largest tributaries and Netzahualc\yotl Reservoir. To this aim, field collections were made during three consecutive years and preserved specimens from the ichthyological collection at El Colegio de la Frontera Sur, San Crist\bal, Chiapas were reviewed. We identified 42 species including new records for the state of Chiapas (3 species), the Grijalva River watershed (3 species), and Netzahualc\yotl Reservoir (2 species). Species composition differed between the upper and lower portions of La Venta River, most likely due to historical factors, and the physical and chemical differences between the two areas. The species composition of the upper parts of La Venta River was distinctive within the watershed but  similar to neighboring hydrologic systems, suggesting that this area was recently connected to other rivers. Our results revealed that the Grijalva River-Tuxtla GutiJrrez watershed is species rich and may be important for describing the distribution patterns of several groups of fishes in Mexico

Fish Species Composition

The fish fauna of urban streams is still poorly known, it difficult to assess the effects of urbanization expansion on fish species composition, for this reason the aim of this study was to provide a checklist of species that compose the ichthyofauna of six urban streams, tributaries to the Vermelho River, upper Paraguay River Basin, Rondonópolis, Mato Grosso State, Brazil. The samples were performed with seine nets on a spatial gradient of 75 m, and with sieves for a period of 15 minutes in each site. A total of 56 species belonging to five orders, Characiformes, Siluriformes, Gymnotiformes, Cyprinodontiformes, and Perciformes, 21 families and 44 genera were sampled. The most common species were Astyanax asuncionensis Géry, 1972, Astyanax abramis (Jenyns, 1842), Odontostilbe pequira (Steindachner, 1882), Odontostilbe paraguayensis Eigenmann & Kennedy, 1903, Characidium zebra Eigenmann, 1909 and Hypostomus sp. This checklist brings additional knowledge on fish that inhabit tributaries to the major rivers of northern Pantanal.
