present survey synthesized information on fish biodiversity in the perennial freshwater body of ramnagar, east midnapore district of west bengal, india. we documented 45 fish species under 29 genera, 18 families and 8 orders during the periods from1990 to 1995, whereas, 34 species from 21 genera and 12 families under 7 orders were recorded presently from freshwater body of different perennial p...

for the purpose of sustainable exploitation of the fishery resources of oni river, ogun state, nigeria, the fish biodiversity assessment was carried out. this was conducted by enumerating and identifying fish species composition, measuring the fish length, fish weight, assessing the fish abundance and biomass, determining the length-weight relationships and the length-frequency of the fishes. a...

the land-locked country of afghanistan has a restricted but relatively diverse ichthyofauna comprising 85 species in 10 families. the fauna is dominated by cyprinidae (50 species) and other ostariophysans (28 species). eight species are endemics to afghanistan within its political boundaries. there are three principal drainage basins: the endorheic amu darya draining to the aral sea with 29 spe...

agunmukha river is an important water body having plentiful aquatic resources. the fisheries communities in the river are familiar with a diverse range of fishing gear and crafts to catch fish. therefore, the objectives of the present study were to explore fishing gear and fishing crafts, catch composition of the respective gearand identification of fish biodiversity of agunmukha river. a step ...

this paper used the results of a research project entitled biodiversity of inland water fishes of iran which was carried out from 2005 to 2010. some 3500 fish specimens were obtained from different basins of iran by using electrofishing method, cast net, gill net and hook. using criteria such as size, shape and color, some of them are considered suitable to keep in aquarium. due to the results ...

The worldwide decline in coral cover has serious implications for the health of coral reefs. But what is the future of reef fish assemblages? Marine reserves can protect fish from exploitation, but do they protect fish biodiversity in degrading environments? The answer appears to be no, as indicated by our 8-year study in Papua New Guinea. A devastating decline in coral cover caused a parallel ...

The study of freshwater fish species biodiversity and community composition is essential for understanding river systems, the effects of human activities on rivers, and the changes these animals face. Conducting this type of research requires quantitative information on fish abundance, ideally with long-term series and fish body measurements. This Data Descriptor presents a collection of 12 dat...

2 Biodiversity is an important factor in all healthy ecosystems. Coral reef ecosystems support an incredibly diverse community of fish species. As coral reefs are in decline due to a combination of factors such as climate change and over fishing, the species which are being supported by the reef are at risk. In particular, coral reef fish communities have been shown to be in decline. Coral reef...

The Guadiana River basin’s freshwater fish species richness and its threatened status in the circum-mediterranean context highlights the need for a large scale study to identify priority areas for their conservation. One of the most common problems in conservation planning is the quantification of a site’s relative value for the conservation of local biodiversity. Here we used a two-tiered asse...
