The first list of fish species from the Río Pilcomayo National Park and Ramsar Site (RPNP), located in the Wet Chaco plains of northern Argentina is presented here. Samplings were carried out bimonthly from December 2006 to January 2008 in sites representative of the different landscapes, in both dry and wet seasons. A total of 77 species were collected, belonging to 23 families and eight orders and covering 54% of the province ichthyofauna. New records to the Province of Formosa are Brachyhypopomus gauderio Giora & Malabarba, 2009; Cyanocharax sp. and Hypophthalmus edentatus Spix & Agassiz, 1829.

Since publication of the previous list (Litvinov & Podolyako, 2013), new data on species composition of fish fauna in the Astrakhan State Reserve have been obtained. As a result of revisions of the collected material and new records (e.g., the first finding of Khvalyn spined loach Cobitis amphilekta Vasil’eva, Vasil’ev, 2012), the list of fish species has been corrected and widened. At present, the list of fish species in the Reserve includes one species of Petromyzontidae and 60 species of Acipenseridae, Clupeidae, Cyprinidae, Cobitidae, Siluridae, Coregonidae, Salmonidae, Esocidae, Lotidae, Atherinidae, Gasterosteidae, Syngnathidae, Percidae, and Gobiidae. Identifications used in previous lists of fishes found in the Astrakhan reserve in 1936–2016 and brief information on biology and dates of latest records of each species are given.

We provide the first list of the ichthyofauna from the Ajó river, a water course situated at the southward border of the Samborombón bay (36°20'12"’ S, 56°54'17" W), a RAMSAR site in Argentina. These results were obtained bi-monthly along two years. Forty-five species belonging to 26 families and 11 orders were identified. This fish fauna is composed by freshwater, euryhaline and marine species. Richest groups were Perciformes and Characiformes, with 10 species each. A single species, Micropogonias furnieri (whitemouth croaker), represented morethan 70 % of the captured specimens, being juvenile individuals only. Remaining species were also represented by juvenile specimens, confirming the importance of this environment as nursery area, particularly for the whitemouth croaker.

The ichthyofauna of the headwaters of the main tributaries of the mighty Solimões/Amazonas River  has been little studied. Considering the importance of those environments for the overall fish  diversity in that river system, we surveyed the composition of the fish fauna of the upper portion  of Purus River and two of its tributaries (Caeté and Macapá rivers), state of Acre, Brazil. The collections were done in November 2004, using a seine net and a set of gillnets of different mesh  sizes. A total of 735 specimens belonging to 86 species and 28 families were collected. Eight  species, Creagrutus occidaneus, Phenacogaster pectinatus, Prionobrama filigera, Moenkhausia cf.  lepidura, Leptagoniates pi (Characidade), Henonemus punctatus (Trichomycteridae), Toracocharax  stellatus (Gateropelecidae), and Eigenmannia macrops (Sternopygidae) composed nearly half of the  specimens collected. This survey adds 48 new records to the ichthyofauna of Purus River and  elevates to 243 the number of known fish species in that river, but a greater sampling effort is necessary to produce a reasonably complete picture of the fish diversity in the basin.

Ichthtyofaunistic survey in perennial Wajoo nullah,an important tribitry of river Ravi in Kathua District, has shown the existence of 64 fish species belonging to 7 orders, 17 families and 42genera. Gudusia chapra and Parambassis bacails are the new records for Jammu and Kashmir State. Fish fauna is dominated by Cyprinifonnes (37 species), followed by Siluriformes (12 species), Perciformes (9 species), Synbranchiformes and Osteoglossiformes (2 species each) and Clupeiformes and Beloniformes (1 species each). Overexploitation, illegal fishing and fishing during breeding season are serious threats to fish resources in Wajoo nullah.

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.

Rara National Park is the smallest national park of the country. It is rich in floral and faunal diversity. Rara is one of the sacred lakes and is listed as a Ramsar site. The aim of the study was to compile the representative flora of Rara lake and to present status of available vegetation. The research used both primary and secondary sources of data. Field visit was conducted in June, 2010 during which more than 300 plant specimens were collected. The secondary data were collected from Rara and adjoining area like Gamgadi. These data were thoroughly analyzed to understand the composition of vegetation. The study revealed the existence of about 224 flowering plant species in the area, under 173 genera and 67 families. Compositae was found to be the largest family (21 species and 17 genera) followed by Rosaceae (19 species and 10 genera).

The present study considered the influence of the tide on shallow water fish assemblages within the Wakatobi Marine National Park, Indonesia. Timed underwater visual observations were made across a gradient of intertidal to subtidal habitats from near-shore to reef crest at different tidal heights. Transient fish were found to dominate shallow water fish assemblages and the assemblage composition varied with tidal state. Fish assemblages were more diverse and abundant at higher tides in both coral and sea grass habitats, however, this was more pronounced within sea grass habitats. A tidal reduction from ≈2.0m to ≈0.8m (above chart datum) corresponded to a 30% reduction in fish abundance, while species richness also significantly decreased from 13.5 to 10.8 species per standardized timed observation. Fifty fish groups were reported from sea grass habitats with the most abundant being from the Engraulidae family and Lethrinus harak, which form important local subsistence fisheries. This research confirms the importance of tidal changes in structuring the fish fauna of Indonesian sea grass habitats and underlines the connectivity that exists between these habitats and nearby coral reefs.
