The study of threats to salmon and endangered species of fish in the river Tysa carried tributaries and in areas watercourse Transcarpathian region using generalized results of hydrological, ichthyological and toxicological studies. Number of species status of populations, evaluated on the basis of documents, monitoring of rivers, ichthyological data during in 2008–2014 years of control catching specialists Department of the use, reproduction of water bio-resources and regulation of fisheries in the Transcarpathian region, the State Administration of Environmental Protection in Zakarpattya region, published and unpublished sources, a survey of local fishermen. Collection and processing of materials performed by conventional methods. Comparison of species composition of fish fauna of the Tysa River Basin within Zakarpattia region on the results of previous studies and the current state of evidence that it has changed significantly. Analysis of data for 1926–2015 years revealed the presence of 77 species, which is 41.5 percent more than the same period in 1926. However, should point to the increase in the number and activities of various threats to salmon and other valuable fish species in our region. Established prolonged human pressure, pollution reduced the number of new European grayling and Trout v 13.4 times. There were 16 species, including salmon, listed in the Red Book of Ukraine. Ceased to meet sturgeon passage. Study threats operation populations of salmon and endangered species gives reason to believe that the level of destruction of natural resources, environmental pollution, depletion of the gene pool is too narrow to study hydro. For the first time a comprehensive assessment of threats to salmon, valuable and endangered local fish Transcarpathia in terms of various specific human impact of their pressure from environmental factors in the past and now. A study of the action of environmental factors and implementation of scientifically based measures to restore fish in close to natural. The results can be used in developing preservation methods, quantitative growth of populations of salmon and endangered species not only in Zakarpattya but also in the Carpathian region, water protection planning activities.

Icthyofaunal study of river Basantar, an important tributary of river Ravi in Samba district, Jammu (J&K) has revealed the existence of 35 fish species belonging to 5 orders, 10 families and 25 genera. There is dominance of Cypriniformes (18 spp.) followed by Siluriformes (10 spp.), Perciformes (4 spp.), Synbrachiformes (2 spp.) and Osteoglossiformes (1 sps.). Present record of 35 fish species when compared with the earlier report of 59 fish species reveals a decline in fish diversity and is caused by environmental factors and anthropogenic pressure.

Dong Nai biosphere reserve (DNBR) is well known for its high level of biodiversity and of global meaningful ecosystem. The fauna includes 84 species of mammals belonging to 28 families, 10 orders; 407 bird species; 141 reptile and amphibian species; 175 fish species; 2,017 insect species. The fish fauna of DNBR maintains many rare and endangered fish species recorded in the Vietnam red book and international union for conservation of nature red list (IUCN's red list) such as Scleropages formosus and many other rare fish species, such as Morulius chrysophekadion, Chitala ornata, Probarbus jullieni, Cyclocheilichthys enoplos… This study was aimed to identify fish composition distributed in DNBR. After the sampling period (01/2019 to 08/2019), a total of 114 fish species belonging to 11 orders and 28 families were recorded in DNBR. There were 09 species of fish on the list of rare and endangered fish species of Ministry of Agriculture and Rural Development of Vietnam, 3 species (Chitala ornata, Cosmochilus harmandi and Hemibagus filamentus) on the Vietnam red list book; 01 species (Ompok bimaculatus) on the IUCN's red list, 11 exotic species, 78 commercial species and 13 species having potential as aquarium fish. In addition, the study also found the first presence of a species of phallostethid, Phenacostethus smithi in DNBR

The fishes of the present study were collected in the headwater streams of the Sorocaba, Paranapanema and Ribeira de Iguape river basins during the dry period in 2010. A total of 2892 fishes, grouped in 53 species, were captured. The composition of the ichthyofauna captured in the streams of Sorocaba and Paranapanema river basin was greatly similar. On the other hand, the fish fauna of the streams of Ribeira de Iguape river basin were quite different from the ones captured in the others basins, with the occurrence of endangered species (Isbrueckerichthys epakmos and I. duseni) and exotic species (Misgurnus anguillicaudatus). The previous list of fish for the Sorocaba river basin increased with the addition of seven species of Characiformes, one Gymnotiformes and four Siluriformes.

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.

Eggs And Larvae

Fish diversity loss is threatened by the construction of dams as they prevent the regular natural dispersal among populations. Thus, conservation of key riverine habitats for fish reproduction may be essential for the recruitment of new native species of fish. The present study aimed to identify key habitats for fish spawning and early development in the Paranapanema River basin, as well as to determine the taxonomic composition, reproductive and life-history strategy, and to report spatial distribution of eggs, larvae and juveniles. The importance of lagoons, tributaries, and sub-tributaries was evaluated in the Paranapanema River basin between October 2012 and March 2013. Eggs and larvae samples were collected at dawn and dusk with conical plankton nets (0.5 mm mesh size), whereas juveniles were captured during the day with seine and sieve (0.5 cm mesh size). A total of 547 eggs, 904 larvae and 1 228 juveniles were captured. We observed that 2 larvae and 288 juveniles of non-migratory species, parental care, and equilibrium life-history strategy, predominated in lagoons and tributaries. On the other hand, 13 larvae and 60 juveniles of short migratory distance, no parental care, and periodic life-history strategy predominated in sub-tributaries. The highest densities of eggs were recorded in tributaries and sub-tributaries (Tukey’s test, P = 0.001 and P = 0.03, respectively), and the highest densities of larvae were recorded for lagoons and tributaries (P = 0.005 and P = 0.0001, respectively). Captures of eggs and larvae were higher at night; while the highest catches per unit effort of juveniles were recorded for tributaries and sub-tributaries. Fish species that adopt different life-history strategies can use diverse types of habitats during the early stages. Lagoons, tributaries and sub-tributaries of the Paranapanema River play different roles in the reproductive success of fish fauna in a heavily modified basin. The preservation of spawning and nursery areas trapped between reservoirs is necessary for Neotropical fish species recruitment and survival. Rev. Biol. Trop. 66(2): 605-621. Epub 2018 June 01.

The fish species composition of Sapucaí-Mirim River is herein reported and discussed in the faunistic context of Grande and Paranaíba river basins, both formers of the Paraná River. The Sapucaí-Mirim is an important tributary of this hydrographic system, flowing to the left bank of Grande River in a region occupied by the reservoir of the Porto Colombia hydroelectric power plant, at São Paulo state northeastern region, in southeastern Brazil. The poorly known fish diversity of the Sapucaí-Mirim River is presented on basis of sampling efforts conducted in the main river channel and three creeks located at the mid and lower sections of the basin, allowing comparisons of the fish fauna of these two sections in the light of available information of fish inhabiting Grande and Paranaíba river basins. The study of the fish composition resulted in the recognition of 68 species in the Sapucaí-Mirim River, belonging to 23 families distributed in seven orders, all commonly found in upper Paraná River basin: Characiformes (32 spp.), Siluriformes (25 spp.), Labriformes (4 spp.), Gymnotiformes (3 spp.), Cyprinodontiformes (2 spp.), Perciformes (one species) and Synbranchiformes (one species). Most of the species are representative of the native ichthyofauna, but the total diversity also includes allochthonous species, which were chiefly found in the lower stretch studied. Some species found in the Sapucaí-Mirim River require great areas for their maintenance, as do large-sized species, known to have migratory reproductive habits. Also, the diversity of small and medium-sized species found and their distinct morphological and biological attributes, allied to the occurrence of endangered fish species, indicate that the Sapucaí-Mirim River basin is an important place for fish diversity maintenance in the Grande River hydrographic system.

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.

The aim of the present study is to asses changes in freshwater ecosistems and fish species compositon, due to human activity, and to cope with this impact, to draw up conteract measurments, according to the particular situations for each site. We have considered to identify artificial and natural polluting sources, which may alter the equlibrium state of the ecosistems, and may cause changes in biodiversity. In order to track these changes we have studied the structure of the fish fauna, chemical and physical parameters of the water, hydromorphological structure of the rivers, which may provide a synthetic overall view upon the status of the waterbodies. These results make up the base of rehabilitation measurment to be taken in order to protect those sites, which still present a good ecological state.
