This study aimed to provide a list of fish species from tributaries of rio das Almas and rio Maranhão basins, in the upper rio Tocantins basin, Goiás State, Brazil. For this study 21 stream stretches were sampled during the dry season in July 2010. A total of 2,279 individuals of 67 species, 19 families and five orders were collected. The most representative families in number of species were Characidae, Loricariidae, and Crenuchidae respectively. The genus Knodus, Hypostomus and Characidium showed the greatest abundance and distribution among the samplings. Poecilia reticulata was considered the only non-native species. The presence of a large number of endemic and undescribed species or with undefined taxonomic situation, in addition to the rapid habitat loss in this region, juts the need for the development of further studies in this basin.

We conducted an ichthyological survey during the dry season of 2006 on the semi-arid islands of Aruba, Bonaire and Curaçao to provide information on species composition, richness and distribution in natural and non-natural aquatic habitats. The dry season species assemblages (N = 9 species) comprised less species than the wet seasons, and these data refine our knowledge of the indigenous fish fauna and its refuge localities during phases of drought and ensuing high salinity. A hierarchical cluster analysis reveals that the three islands have different species compositions with Curaçao being the most diverse, probably due to its having the most habitats and freshwaters present throughout the year. Species richness was unrelated to salinity and species diversity was highest in canalised streams. In the dry season fewer amphidromous species are present than in the wet season. We found no significant effect of human-induced changes on the presence or absence of fish species in the Netherlands Antilles. The presence of exotic species (including Xiphophorus helleri on Aruba, a first record for this island, and Oreochromis mossambicus and Poecilia reticulata occurring on all three islands) did not have a clear effect on the presence of indigenous species, nor did human alteration of the habitats have an influence on the occurrence of fish species.

AbstractThe knowledge of biotic and abiotic drivers that put non-native invasive fishes at a disadvantage to native ones is necessary for suppressing invasions, but the knowledge is scarce, particularly when abiotic changes are fast. In this study, we increased this knowledge by an analysis of the biomass of most harmful Prussian carp Carassius gibelio in a river reviving from biological degradation. The species' invasion followed by the invasion's reversal occurred over only two decades and were documented by frequent monitoring of fish biomass and water quality. An initial moderate improvement in water quality was an environmental filter that enabled Prussian carp’s invasion but prevented the expansion of other species. A later substantial improvement stimulated native species’ colonization of the river, and made one rheophil, ide Leuciscus idus, a significant Prussian carp’s replacer. The redundancy analysis (RDA) of the dependence of changes in the biomass of fish species on water quality factors indicated that Prussian carp and ide responded in a significantly opposite way to changes in water quality in the river over the study period. However, the dependence of Prussian carp biomass on ide biomass, as indicated by regression analysis and analysis of species traits, suggests that the ecomorphological similarity of both species might have produced interference competition that contributed to Prussian carp’s decline.

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.

Taxonomic Description

The aquatic habitats of the Taquari-Antas river basin (in the Patos Lagoon basin, southern Brazil) are under marked environmental transformation because of river damming for hydropower production. In order to provide an information baseline on the fish fauna of the Taquari-Antas basin, we provide a comprehensive survey of fish species based on primary and secondary data. We found 5,299 valid records of fish species in the basin, representing 119 species and 519 sampling sites. There are 13 non-native species, six of which are native to other Neotropical river basins. About 24% of the total native species are still lacking a taxonomic description at the species level. Three native long-distance migratory species were recorded (Leporinus obtusidens, Prochilodus lineatus, Salminus brasiliensis), as well as two potential mid-distance migrators (Parapimelodus nigribarbis and Pimelodus pintado). Although there is only one officially endangered species in the basin (S. brasiliensis), restricted range species (21.7% of total species) should be considered in conservation efforts.

Endemic Fish

Due to its peculiar geographical position and its environmental heterogeneity, Turkey represents an important biodiversity hotspot for freshwater fish fauna. Unfortunately, native fish communities of Turkey, mainly from lentic ecosystems, have been massively altered in the past decades. Furthermore, these species, especially the endemic species, are now threatened by several human activities in addition to the global issue of climatic changes. The aim of this paper is to provide an updated review on the current status of endemic fish species from main lakes of Turkey including major threats affecting fish assemblages. By gathering data from the literature and authors’ personal observations, 62 endemic fish species were reported to occur in the considered 37 Turkish Lakes. The presence of non-native species, agriculture activities, climatic drought, and decreasing water level were found to be the threats that most affect the fish communities of the considered Turkish Lakes.

Abstract: In the present work, we conducted an extensive long-lasting inventory of the fishes, using different collection methodologies, covering almost the entire Pindaré River drainage, one of the principal tributaries of the Mearim River basin, an area included in the Amazônia Legal region, northeastern Brazil. We reported 101 species, just three of them being non-native, demonstrating that the composition of this studied fish community is majority composed of native species. We found a predominance of species of the orders Characiformes and Siluriformes, corroborating the pattern usually found for the Neotropical fish fauna. Similar to other studies, this inventory was mainly dominated by small characids, representing 21% of the species herein recorded. When comparing the present survey with other species lists published for this region (including the States of Maranhão and Piaui), we can conclude that the freshwater fish fauna of the State of Maranhão is probably still underestimated. We reported 41 more species, and one more species than Soares (2005, 2013) and Abreu et al. (2019) recorded for the entire Mearim River basin, respectively. We believe, however, that the number of species presented by Abreu et al. (2019) is overestimated. We compared our results with all other freshwater fish species inventories performed for the hydrological units Maranhão and Parnaíba sensu Hubbert & Renno (2006). With these comparisons, we concluded that our results evidenced that a high effort was put in the inventory here presented. The two works including more species recorded from coastal river basins of the hydrological units Maranhão and Parnaíba were the works published by Ramos et al. (2014) for the Parnaíba River basin, one of the main and larger river basin of Brazil, and the compiled data published by Castro & Dourado (2011) for the Mearim, Pindaré, Pericumã, and upper Turiaçu River drainages, including 146 and 109 species, respectively. Our survey recorded only 45 less species than Ramos et al. (2014), and eight less species than Castro & Dourado (2011). However, it is essential to emphasize that the number of species presented by Castro & Dourado (2011) is probably overestimated since they did not update and check the taxonomic status of the species of their compiled data. In several cases, they considered more than one name for the same species.

Abstract: The Guareí River is a tributary of the Paranapanema River (Brazil), located in the upper portion of the Jurumirim Reservoir. Fish fauna studies in this watershed began in the 2000s, but they were restricted to a few waterbodies. This work conducted a broad survey of the fish fauna in tributary streams and the main channel of the Guareí River. Sampling occurred between February 2017 and November 2018 at 36 sites and using different collection methods. We captured 2,169 specimens belonging to 50 species, 16 families and 6 orders. The species accumulation curve tended to stabilize but indicated that species richness is underestimated. Almost all species are native (46); only three were non-native (Hyphessobrycon eques, Oreochromis niloticus and Poecilia reticulata) and one was undefined (Gymnotus pantanal). Among the native species, two are unknown to science (Bryconamericus aff. iheringii and Hypostomus sp. n.) and three are migratory (Leporinus friderici, Megaleporinus obtusidens and Pimelodus maculatus). In this paper, we provide images of species collected. Results indicate that the Guareí River basin is a hotspot of fish diversity in the Upper Paranapanema River, stressing the need for adequate management and conservation actions.

The Itapecuru is a relatively large river in the northeastern Brazilian state of Maranhão. During several expeditions to this basin, we collected 69 fish species belonging to 65 genera, 29 families and 10 orders. Characiformes and Siluriformes were the orders with the largest number of species and Characidae, Loricariidae, Cichlidae, Auchenipteridae and Pimelodidae were the richest families. About 30% of the fish fauna of the Itapecuru basin is endemic or restricted to northeastern Brazil. Just over a fifth (22%) of the species is also known to occur in the Amazon basin and only a few are more widely distributed in South American.

Preliminary Study

Batetangnga River is one of the rivers in West Sulawesi and is well known as an ecotourism area. This preliminary study was performed to reveal fish fauna in the Batetangnga River, West Sulawesi. Ichthyofauna research was conducted in April and May 2021 at two stations in Batetangnga River, namely Rawa Bangun and Butute’neng. During the study period, a total of 14 species belonging to 9 families were identified. No endemic species were found in the study area. Native fish species such as Stiphodon semoni, Butis butis, Glossogobius sp., Glossogobius aereus, Stiphodon sp., Giuris sp, Atule sp. Ambassis miops, Ambassis interrupta, Microphis sp. were recorded. Four alien fishes species were documented i.e. Aplocheilus panchax, Poecilia reticulata, Anabas testudineus, and Oreochromis niloticus. Freshwater fish exploration and efforts to control alien fishes species in west Sulawesi are essential things to be done shortly.
