Annotated checklist of the freshwater fishes of continental and insular Costa Rica: additions and nomenclatural revisions

Based on a combination of intensive literature review, electronic database searches, re-identification of museum specimens and fieldwork, we hereby provide an updated checklist of the freshwater fishes of continental and insular Costa Rica. This checklist, systematically arranged at the ordinal and familial level, includes nomenclatural revisions, distributional information, and when appropriate, cross-references on the basis of Bussing (1998). According to our results, the native Costa Rican freshwater fish fauna is composed by 250 species, divided into 119 genera, 49 families and 19 orders; increasing in 108 the number of species originally reported by Bussing (1998). By far, the vast majority of these species, according to their supposed tolerance to salinity, are peripheral (63.2%), followed by secondary freshwater fishes (23.6%); only 13.2% are primary freshwater fishes. 24 species in this checklist appear to be endemic to Costa Rica. In addition to the native fauna 8 exotic species are reported.

Tolerance To Salinity

The inland fish fauna of El Salvador and its distribution was originally described in 1925 by Samuel Hildebrand. That work has been the main source of information for freshwater fishes of El Salvador up to today. Based on the combination of an intensive literature review, electronic database searches, re-identification of museum specimens, and fieldwork, we hereby provide an updated checklist of the inland fishes of El Salvador. This checklist provides distributional data at the Salvadoran hydrographical and political (by department) levels. The checklist is systematically arranged at the ordinal and familial level and then alphabetically therein. The freshwater fish fauna of El Salvador includes 101 species divided into 64 genera, 29 families, and 14 orders. According to their supposed tolerance to salinity, 73% of these species are peripheral, 23% secondary, and only 4% are primary freshwater fishes. One species is endemic to the country, Amatitlania coatepeque. The low number of primary freshwater fishes and endemics is comparable to the Central American Pacific slope in particular, as well as northern Central America in general.

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.

Dispersal Capability

Secondary salinisation represents an important threat to terrestrial and aquatic habitats throughout the world. In south-western Australia, widespread salinisation of waterways has caused large range reductions in the highly endemic freshwater fish fauna. We hypothesised that differences in the distributions of three fish species within the salinised Blackwood River would be related to their salinity tolerances. Galaxias occidentalis was widespread throughout the catchment, whereas Nannoperca vittata was restricted to the main channel and freshwater tributaries of the lower catchment, and Nannatherina balstoni was restricted to those tributaries and a perennial section of the main channel that received a considerable amount of fresh groundwater. Acute salinity tolerances (Effect Concentrations) of G. occidentalis and N. vittata were similar (EC50 ∼14.6 g L–1), but significantly greater than that of N. balstoni (EC50 ∼8.2 g L–1). The greater geographical range of G. occidentalis, compared with N. vittata, may be a consequence of the dispersal capability of the former species, and the lower salinity tolerance of N. balstoni contributes to its highly restricted range. The findings demonstrate that secondary salinisation has greatly impacted these freshwater fishes, and fresh groundwater refuges, predicted to decrease due to reduced rainfall, appear crucial in maintaining remnant populations.

Host Parasite

As a part of an ongoing inventory of the helminth parasites of freshwater fishes in Mexico, 676 specimens were collected between November 2007 and December 2008 in 23 localities along the upper Mezquital River Basin in Durango State, northern Mexico. Sixteen species of hosts, mostly corresponding to Nearctic freshwater elements, were studied. A total of 1,230 individual worms were collected during this survey, representing 25 species of endohelminths of which 9 were digeneans, 3 were cestodes, 4 were acanthocephalans, and 9 were nematodes. The checklist contains 24 new hosts and 42 new locality records. The information provided in this checklist may be helpful for our understanding of the biodiversity and historical biogeography of this host-parasite system, since the Mezquital River Basin mostly contains a Nearctic freshwater fish fauna, with a few Neotropical and endemic elements and may represent a transitional area from a biogeographical point of view.

Australian Freshwater

As the driest inhabitable continent, it comes as no surprise that Australia has comparatively few species of freshwater-dependent fishes compared with land masses of similar size and latitudinal coverage. In addition to relatively low rainfall and few permanent waterbodies, a range of other climatic, geological, physical, and biogeographical factors are generally offered up, to account for the low species count in a country otherwise regarded as mega-biodiverse. Here, we challenge this traditional view by hypothesising that Australia’s lack of freshwater fishes largely reflects a dearth of detailed taxonomic activity. Using both allozyme and mtDNA markers, we undertook a molecular assessment on the Australian purple-spotted gudgeons (Mogurnda), recently subjected to a taxonomic revision that saw a three-fold increase in the number of described species. In addition to demonstrating additional, species-level biodiversity within M. adspersa, our genetic data revealed discordant patterns of mitochondrial and nuclear genetic affinities among populations in several species, plus a sister relationship between the two central Australian species. We discuss the broader implications of such cryptic biodiversity for the Australian freshwater fish fauna; most notable among these is our prediction that only 50% of species have been described.

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 Jordans freshwater fish fauna.

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.

A checklist of the fishes of the Tusubres River basin, Pacific coast of Costa Rica, compiled from field and museum surveys is herein presented. A total of 54 species, representing 47 genera and 27 families, were recorded. Peripheral species were dominant (64.8%), followed by secondary freshwater fishes (20.4%); primary freshwater fishes accounted only for 14.8% of the total fish diversity. Eleotridae (6 spp.), Gobiidae (6 spp.), Poeciliidae (5 spp.) and Characidae (4 spp.) were the most diverse. Two species (Caranx sexfasciatus, Carangidae; and Opisthonema libertate, Clupeidae) were new records for Costa Rican freshwaters, and two species (Gymnotus maculosus, Gymnotidae; and Lebiasina boruca, Lebiasinidae) was found to have expanded ranges. An identification key and a complete photographic album of all fish species recorded in the basin are presented. The results of this investigation provide a framework for future studies on biogeography, ecology and conservation on fishes from this area.

Annotated Checklist

An annotated checklist for the freshwater fishes from Paraná State, Brazil is provided. A total of 440 freshwater fish species are recorded for the state, distributed across five ecoregions: Upper Parana, Lower Parana, and Iguassu, all within the rio Paraná basin, and corresponding to the state’s Inland Slope, and Southeastern Mata Atlantica and Ribeira de Iguape, corresponding to the Atlantic Slope, encompassing minor coastal drainages emptying in the Baía de Paranaguá or in the Baía de Guaratuba, and the rio Ribeira de Iguape basin, respectively. The Upper Parana ecoregion ocuppies the larger in area in the state, and is divided into the following sub-ecoregions: Floodplain, Paranapanema, Piquiri, and Ivaí. Species richness for each ecoregion is as follows: 273 species for the Upper Parana (Paranapanema sub-ecoregion, 217 species; Floodplain sub-ecoregion, 193 species; Piquiri sub-ecoregion, 154 species; Ivaí sub-ecoregion, 132 species), 154 species in the Lower Parana, 127 species in the Iguassu, 68 species in the Southeastern Mata Atlantica, and 50 species in the Ribeira de Iguape. We recorded 42 putatively undescribed species and 117 endemic species from specific ecoregions (except Upper Parana) or sub-ecoregions in the state. Ninety-eight species recorded are non-native from at least one of the state’s ecoregions. Thirty-three species are considered threatened. The ecoregions in the Atlantic Slope share many more species with each other than with ecoregions in the Inland Slope. The Iguassu ecoregion is the only one located in Inland Slope that shares more species with the Atlantic Slope than with the remaining ecoregions from the Inland Slope. The Ivaí sub-ecoregion lacks several species that are common to all other sub-ecoregions of the Upper Parana ecoregion. Comments on the historical development of taxonomic knowledge, biogeography, threats, and conservation strategies for the fish fauna from the Paraná State are provided.
