Freshwater Fish Fauna

This research aims improved data of the species and abudance freshwater fish for conservation planning Mamberamo region.  The survey was lasted 18 days from 5 February to 24 April 2008 in several habitat consists river, creeks, oxbowlake and stream. A total at least 20 species in 17 genera and 14 families were collected were captured using gillnet, castnet, handnet, longline and poisson plant from Deris sp. Two species new record for Mamberamo that is Chilaterina lorentzi was previously know only from Tawarin river on the north coast Papua about 200 km west Jayapura and Puive creek, tributary of the Pual River near Vanimo, PNG and Monopterus albus (intoduction fish) was not previously know in Mamberamo although Papua. The generally freshwater fish fauna were collected in Haya about 70 % similar to record from Dabra.

Freshwater Fish Fauna

Considerable changes were revealed in the indigenous freshwater fish fauna during a field survey of six years from 2006 to 2008. Most of them are endangered and one endemic species, Aphanius sirhani, is under the threat of extinction. Four other species, Garra rufa, G. ghorensis, Nemacheilus insignis and  Aphanius dispar richardsoni are also endangered. Misuse of the limited water resources, intensification of agriculture, overexploitation of fishing and the  introduction of exotic species are considered to be major threats to Jordan’s  freshwater fish fauna.

Annotated Checklist

The knowledge of the Costa Rican freshwater fish fauna continues to grow given the discovery of new taxa, the recognition of taxa resurrected from synonymy and the corroboration of new country records and new range extensions. Moreover, recent advances in the understanding of the phylogenetic relationships and status of many supraspecific groups have led to numerous taxonomic and nomenclatural changes. Given this, the purpose of this paper is to update the known composition, distribution and clasification of the Costa Rican freshwater fish fauna taking as reference the most recent list for the country published by Angulo et al. (2013). A total of 23 new country records (i.e., species; distributed in 17 families and 21 genera), 33 new range extensions (distributed in 20 families and 30 genera) and several nomenclatural changes are reported, illustrated and discussed here. An updated and annotated checklist of the freshwater fishes of the country (including data for a total of 283 species, 13 of which are exotic, distributed in two classes, 27 orders, 55 families and 136 genera) is also provided.

Freshwater Fish Fauna

Hainan Island is located within the Indo-Burma global biodiversity hotspot, however, the freshwater fish fauna on this island is poorly understood. Based on field investigations and literature review, we compiled a list of 154 freshwater fish species (138 native and 16 non-native) belonging to 10 orders, 31 families and 104 genera found on Hainan Island. Of these, 31 species are endemic to China. The native freshwater fish fauna in Hainan Island is affiliated to South China sub-region of the Oriental Region. Current knowledge suggests that overexploitation, water pollution, flow modification, habitat degradation, and non-native species have severely reduced the freshwater fish biodiversity in Hainan Island. To protect freshwater fish biodiversity and fisheries in Hainan Island, some new measures should be adopted and current measures better enforced. This study constitutes an important resource for conservation management of freshwater fishes in Hainan Island.

The freshwater fish fauna of Pakistan is briefly discussed. It is predominantly South Asian but High Asian and West Asian elements are also present. The African element is hardly perceptible. Five zoogeographical divisions of Pakistan are proposed on the basis of the composition of their fish fauna: (I) the High Asian Division; (II) the Aba-Sinh Division; (III) the Northwestern Montane Division; (IV) the Indus plain and adjoining hills Division; and (V) the Northwestern Baluchistan Division. South Asia and High Asia are recognized as two subregions within the Oriental Region, while West Asia is treated as a transitional region.

Freshwater Fish Fauna

We conducted a phylogeographic analysis of the genus Gephyrocharaxin Venezuela to evaluate geomorphologic evidence for the formation of the country's main watersheds and to establish a biogeographical hypothesis of possible diversification mechanisms of the Neotropical freshwater fish fauna. We assayed eight enzyme systems and general proteins to estimate genetic variability (H, P), intraspecific structuring in several Gephyrocharax valencia and G. venezuelae populations (FIS, FIT, and FST), and a phylogenetic approach for the three species of Gephyrocharax in Venezuela, using Corynopoma riisei as the external group. Fourteen presumptive lociindicate that populations of the three species of Gephyrocharaxanalyzed show a clear genetic inter-specific differentiation, determined by four loci with fixed alleles (GPI-B*,IDH*, ME-1*, and ME-2*). The resulting cladogram shows two major clades: a monophyletic group consisting of Gephyrocharax n. sp. and G. venezuelae(restricted to the northwest of the country) and a group formed exclusively by G. valencia (distributed along the largest geographic range). Speciation of the Venezuelan lineages of the genus Gephyrocharaxcould be explained by the origin and course movements of the present Orinoco River together with geomorphologic processes that have occurred in northern Venezuela since the Miocene.

Morphological Differences

A species of the genus Rectoris Lin, 1935 newly recorded from Northeast of Vietnam is Rectoris longibarbus. This species were collected in Bang Giang river, territory of Cao Bang province and Ky Cung river, territory of Lang Son province. The genus Rectoris Lin comprises 5 species worldwide, mainly distributed in Asia. In Vietnam, up to date there were 2 species belonging to the genus Rectoris recorded. Based on the samples is collected of Rectoris, as well as domestics and foreign publiccations, we found one species, Rectoris longibarbus Zhu, Zhang & Lan as a new record for freshwater fish fauna of Vietnam. The newly recorded species has the morphological differences with the already known species of Vietnam, thus the total number of species of this genus is three. In this paper some detailed description of morphological characteristics of Rectoris longibarbus is gived. A key to species of the genus inVietnam is also provided.
