We present here a detailed account of the diversity, distribution, threats, and conservation of freshwater fishes in the upper-catchment of the Kabini River in the Wayanad part of the Western Ghats Biodiversity Hotspot.  A total of 136 fish species belonging to 13 orders, 29 families, and 69 genera were recorded.  Order Cypriniformes dominated with five families, 36 genera, and 84 species, and Cyprinidae was the dominant family represented by 51 species within 21 genera.  The true diversity of ichthyofauna in this catchment, is still unclear and requires further exploration and taxonomic studies.  At least 44 species recorded during the study are endemic to the Western Ghats, of which 16 are endemic to the Cauvery River System and two species endemic to the Kabini Catchment.  A total of 20 non-native fish species were recorded from the study area, of which six species were inter-basin (within India) transplants and 14 species were exotic.  Among the native species with confirmed identity, four are Critically Endangered (CR) and nine Endangered (EN) as per the IUCN Red List of Threatened Species.  As a part of the study, we also extend the distribution ranges of Opsarius malabaricus, Laubuka trevori, Opsarius bendelisis, Puntius cauveriensis, Oreichthys coorgensis, Mesonoemacheilus pambarensis, Hypselobarbus curmuca, and Pseudosphromenus cupanus to the Kabini Catchment.  The presence of four species, which were earlier considered to be endemic to the west flowing rivers of the Western Ghats, viz, Laubuka fasciata, Hypselobarbus kurali, Sahyadria denisonii, and Puntius mahecola, in an east flowing stream is reported and discussed.  Deforestation and removal of riparian vegetation, pollution, stream channel modification, sand mining, destructive fishing practices, dams and other impoundments, monsoon fishing, and non-native species are the major threats to freshwater fishes in the region.  Strategies for the conservation of aquatic ecosystems in the Kabini Catchment are discussed.

The ichthyofauna of Cauvery Wildlife Sanctuary is comprised of 58 species belonging to 18 families and 44 genera of which close to 25% are endemic to the Western Ghats region, and eight are endemic to the Cauvery River system namely, Dawkinsia arulius, Dawkinsia rubrotinctus, Hypselobarbus dubius, H. micropogon, Kantaka brevidorsalis, Labeo kontius, Tor remadevii and Hemibagrus punctatus.  Eight species found in Cauvery Wildlife Sanctuary are threatened, including two (Tor remadevii and Hemibagrus punctatus) listed as ‘Critically Endangered’, four species (Dawkinsia arulius, Hypselobarbus dubius, H. micropogon, and Silonia childreni) as ‘Endangered’ and two (Hyporhamphus xanthopterus and Wallago attu) as ‘Vulnerable’ on the IUCN Red List.

A checklist of fish fauna, comprising 40 species representing 15 families and 9 orders, was compiled from field, museum, and literature surveys of the Shubuto River System, southwestern Hokkaido, Japan. This area approximates the boundary of southern/northern affinities of Japanese freshwater fishes. All primary freshwater species, are listed except for Gymnogobius castaneus and all anadromous and marine amphidromous species that are scientifically presumed to occur naturally in the area. The list contains two invasive exotic species, Cyprinus carpio and Oncorhynchus mykiss, and two Siberian primary freshwater species, Lefua nikkonis and Barbatula toni, which are thought to mark the boundary of southern and northern affinities of Japanese freshwater fishes. Rhynchocypris perenurus, another Siberian primary freshwater species with a similar presumed range, was not recorded. The voucher specimen species included Platycephalus sp. 2, which is suggested to have the northernmost extended range.

AbstractOreochromis mossambicus (Peters 1852) and Oreochromis niloticus niloticus Linnaeus, 1758 are two popular freshwater fishes introduced from Africa to India. There are many records of different species of trichodinid ectoparasites infesting wild and cultured cichlids in Africa, but no such study has been conducted on this parasitic group in India. The fishes Oreochromis mossambicus and Oreochromis niloticus niloticus were investigated for the occurrence of trichodinid ciliophorans. Oreochromis mossambicus was found positive for two species, viz., Trichodina centrostrigeata Basson, Van As & Paperna, 1983 and Paratrichodina africana Kazubski & El-Tantawy, 1986. Oreochromis niloticus niloticus was found not to be infested with any species of trichodinid ciliophorans, although, interestingly, Paratrichodina africana was first discovered in this host fish. Comparative descriptions and prevalence of these two above-mentioned species are presented.

Fish Endoparasites

The fish health status and parasitic infection in paddy fields are understudied in Borneo. This study was done to compare the prevalence and abundance of parasites on freshwater fishes in the upstream and downstream rivers of paddy fields. Parasite study on freshwater fishes was done by collecting live fish samples using ten minnow traps with baits at each site in Serian and Padawan, Sarawak, from October 2017 until March 2018. A total of 120 freshwater fishes were examined during this study period. Cold anaesthesia was applied on live samples prior to ectoparasite and endoparasite microscopic screening, which involved scraping of outer body mucous and removal of fish intestines, respectively. No ectoparasites were recovered from the fish samples. A total of 19 (15.83%) fishes from Cyprinids were infected with endoparasites. From these, 58 individuals of endoparasites were recovered. Two groups of parasites, namely Nematoda (Cucullanus sp.) and Trematoda (unidentified), were recovered from the fish intestines. From this study, there was a significant difference between the upstream fishes and downstream fishes in their endoparasite infection at both Triboh Village (p = 0.035) and Annah Rais Village (p = 1.445 × 10-6) using two samples t-test. The endoparasite abundance in fish was higher in the streams where there was less human disturbance. This study may serve as a baseline study on the parasitic infections of freshwater fishes in streams near paddy fields or other agricultural area in Sarawak.
