Fishes are very important food resources in developing countries, due to high protein content and its nutritional value. The present study deals with Ichthyofaunal diversity of Bhagar oxbow Lake, in Dumraon, District, Buxar. Total of 44 freshwater fish species were listed that belonging to 30 genera, 16 families and 7 orders, described in the present study from February, 2018 to January, 2020. Among them Cypriniformes was the dominant order in term of species diversity that represent (16 species) while the Puntius is the most dominant genus, and held a major portion of the lake. Siluriformes (11 species), Perciformes represented with 6 species, Channiformes (4 species), whereas Mastacembeliformes & Clupeiformes represented (3 species) each and Tetraodontiforme represented only (1 species). Fish of the family Cypriniformes was the most abundant 37.20% of the total fish species followed by the family Siluridae 25.58% and Perciformes 13.95% were reported. Order Channiformes represent 9.30%, followed by the family Clupeiformes 6.97%, Mastacembliformes, 4.3% and Tetrodontiform represented with 2.32% of the total fish species. In the Bhagar oxbow lake, a large number of fish species have edible as well as ornamental and medicinal values. The species composition of ichthyofaunal diversity can also be better understand by this paper. This is the first ever study on the fish diversity and would help in explore the fish fauna and to develop a sustainable fishery practices need to Bhagar oxbow lake in Dumraon.

Faunal Diversity

Fresh water wetlands are fragile ecosystems, which are fast deterioring and shrinking due to manmade activities. The fish composition of Huchharayanakere of Shikaripura was studied for a period of twelve months from January to December 2015. The icthyo-faunal diversity of this pond confirmed the occurrence of 13 species of fishes belonging to 5 families. The family Cyprinidae represented by 9 species. Families Anabantidae, Bagridae, Clupeidae and Notopteridae were represented by only a single species. Simultaneously the physico-chemical condition of the water body revealed that water quality is suitable for fish culture. The study of fish fauna of an aquatic body is useful for planning of fisheries development. The pond needs proper management and utilization of this fish wealth and sustainable steps to monitor and conserve the fish health. The present study revealed that Huchharayanakere of Shikaripura harbors wide varieties of fish with economic importance in local and global trade. The study will provide future strategies for development and fish conservation.

Large, long-lived lakes, such as Lake Baikal and the African Great Lakes are known for their diverse endemic faunas. Nearby smaller isolated lakes have long been hypothesised to facilitate allopatric speciation, such as Lake Nabugabo at the edge of Lake Victoria, helping seed the radiation in the large lakes. Furthermore, crater lakes, formed by volcanic activity are often deep, long-lived and relatively isolated, and often host a number of closely-related endemics, becoming model systems for testing theories of sympatric speciation and adaptive radiation, such as Lakes Barombi Mbo in Cameroon, and Apoyo in Nicaragua. Here we report on studies of 9 crater lakes in southern Tanzania: Lakes Ikapu, Ilamba, Itamba, Itende, Kingiri, Kyungululu, Masoko (=Kisiba), Ndwati and Ngozi, plus the shallow satellite lakes Chikukutu and Chilingali in central Malawi. Additional notes are presented about fish species present in nearby river systems. The lakes differ considerably in surface area, depth and water chemistry. No permanently aquatic animals were observed in Lake Ngozi, the largest of the lakes, nor in Lake Ndwati. All of the other 7 craters lakes were found to contain cichlid fishes, comprising a total of 29 populations of which 24 are considered likely to be native, many meriting recognition as distinct species. At least one lake (Masoko) contains a diverging pair of cichlid ecomorphs likely to be undergoing sympatric ecological speciation. Another case might be the dwarf and large ecomorphs of Rhamphochromis in Lake Kingiri. In addition, 4 crater lakes are reported to contain members of other fish families: Clariidae, Cyprinidae, Danionidae and Procatopodidae. The lakes also hosted a variety of macro-invertebrates, including crabs, bivalves and gastropods. There is evidence of repeated attempts to stock all of these lakes with non-native fish species, in at least one case leading to the establishment of breeding populations of two species. This represents a major threat to these unique ecosystems. In Malawi, Lakes Chilingali and Chikukutu were recently joined as a result of damming of the outflow of the former. This ‘large Chilingali’ hosted a diverse fish fauna, including two apparently endemic haplochromine cichlid fishes of the genera Lethrinops and Rhamphochromis. The lake was heavily fished and attempts had been made to stock cages for tilapia culture using non-native populations of species already present in the lake. However, the dam was allowed to erode and it finally collapsed in 2011-13, resulting in the restoration of the previous condition of two inter-connected lakes. Little is known of the pre-impoundment lakes, but post-collapse, the lakes became shallow and swampy, with apparently greatly reduced fish diversity. Neither endemic species could be found when the lakes were sampled in 2016. Our work has indicated that the satellite lakes of Lake Malawi are important reservoirs of biodiversity that can play a major role in our understanding of speciation and adaptive radiation, but they are fragile systems currently threatened by poor management practices including intentional stocking of non-native fish.

<p>The delta of Orinoco River constitutes a long estuarine extension of a great importance to fisheries at Venezuela, because, it is an indispensable area for reproduction, feeding and growing of several fish species, most of them with a commercial application. The purpose of this research was to identify and analyze the changes in fish diversity and the structural dynamic of the community at four zones of channel Manamo, during dry and rainy season. Samples were taken on March and May for dry period and July and August for rainy season. A total of 48 species were identified, grouped into 24 families and 42 genera. The diversity was higher in Bajo del Medio during the dry season (2.58 bits/ind), decreasing to 1.66 bits/ind in el Pajar (rains). The PERMANOVAS analyzes showed statistical differences in the composition of species with respect to the climate season (psed-F = 0.0365, <em>p</em> &lt;0.05), but not between the sampling stations (psed-F 0.6668; <em>p</em> &lt; 0.05). The results indicated that the fish fauna of the region is composed of elements characteristic of an estuary, being the climate seasons the most important factors for the evaluated group and this reflects the seasonal nature of this community.</p>

Diversity, potentiality and conservation status of fish fauna in upper Mahakam’s tributaries of east Kalimantan is unknown. The purposes of this study were to analysis species diversity, determine potentiality and conservation status of fish fauna in upper Mahakam’s tributaries, east Kalimantan. Fish sampling with purposive method was conducted in four tributaries, i.e Tepai River, Pahangai River, Danum Parai River, and Meraseh River for one month. Fishes were collected by several gears type. The results of this research showed that the total number of fish caught was 820 individuals; consist of 26 species, 7 families, and 4 orders. The Cyprinidae was the most dominant family found in all tributaries. The Shannon-Wiener diversity index in four tributaries were varied and ranging from 1.749-2.087. The highest fish diversity was recorded at Maraseh River followed by Pahangai River, Danum Parai River, and Tepai River. The low fish diversity was discovered at Tepai River may be due to differences in substrate type, water velocity, and water depth as compared to the Maraseh River, Pahangai River, Danum Parai River. The fish species similarity coefficient between four tributaries ranged from 0.606-0.842 and the highest dissimilarity was found between Tepai River and Danum Parai River. Almost all fishes categorized as edible fish for local consumption. Syncrossus hymenophysa and Gastromyzon lepidogaster have potential as ornamental fish. Regarding IUCN red list status, six fish species were grouped into least concern status, two species as data deficient, one species as near threatened, one species as endangered species and 16 other species were not on the list.

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.

Abstract Freshwater fish diversity, abundance, the ecological indices, and water quality from Main Outfall Drain (MOD) in Al-Diwaniya City/middle Iraq were studied monthly from January to December 2017 in two sites. The present study has shown that the third river (MOD) supported 15 fish species belonging to 7 families. As far as biodiversity status in fish community (IUCN-2019) is concerned, out of 15 species, eleven fish species are categorized into Lower risk least concern (LC or LR/lc), four Vulnerable (VU). Eight species were sensitive to salinity; seven species were tolerance. The results were concluded that the properties of water were tolerable for the fish community. Ultimately, it can be concluded that the sector of MOD supported the fish community. But it needs constant monitoring for the conserve and development of the diversity and the case of the healthy fish.

Indigenous Fishes

The aboriginal ichthyofauna of the Balkhash basin consists mainly of endemic fish species. By the end of the last century, indigenous fish species were driven out of Lake Balkhash and the Alakol Lakes remain the largest refuges of aboriginal fish fauna. Knowledge of regularities of the modern distribution of the indigenous fishes is crucial for biodiversity conservation as well as restoring aquatic ecosystems. The modern diversity of fish species was investigated there in this study. Significant changes for the indigenous and some alien fish distributions were revealed in contrast with earlier known data. Canonical correspondence analysis (CCA) was used to study the relationships between habitat characteristics and species abundance. Water mineralization and maximal observed water temperatures were estimated as the main environmental variables in fish distribution at the local scale. Habitat change leads to fish fauna homogenization as a result of rare species extinction and alien penetration. Growing human population and poor water management make the future of the indigenous fishes unpredictable.
