  • Title
    Diversity, threats and conservation of catfish fauna of the Krishna River, Sangli District, Maharashtra, India
    Type
    Journal Article
    Description
    The diversity of freshwater catfish species of the Krishna River, Sangli District was studied from June 2009 to July 2012. The study area covered 105km from Karad City where the Koyna tributary joins the Krishna River up to Mhaishal, the state border of Maharashtra. It was divided into three streams for convenience, i.e., the upper stream starts from Karad and goes up to Takari, the middle stream from Takari to Bhilawadi and downstream from Bhilawadi to Mhaishal. A total of 13 species of catfish belonging to five families and 10 genera were recorded. The Bagridae family was dominant with six species, whereas Siluridae, Schilbidae and Clariidae had two species each and Sisoridae with one species. We have provided range extension for an endemic and threatened sisorid catfish Glyptothorax poonaensis. The occurrence and distribution of catfishes was more or less equal in number along the study area. The maximum number of species recorded was nine from the upper stream, whereas the middle and down streams had eight and seven species respectively. The distribution of catfish along the Krishna River system may be due to the slow and steady state water movement and its width that ensure the continuous availability of nutrition. It is suggested that the Krishna River would be a suitable habitat for the conservation of freshwater catfish if the threats are minimized.

  • Title
    Distribution of catfishes in wetlands of two flood plain districts in Tamil Nadu, India
    Type
    Journal Article
    Description
    A study was conducted on the distribution of catfishes in selected wetlands in Kancheepuram and Kanyakumari districts of Tamil Nadu, southern India. Different types of wetlands such as tanks, pools, lakes, open wells and estuaries were selected for the study based on their different environmental set up. Fishes were collected with the help of fishermen using cast and seine nets. Twelve species of catfishes from five families (Ariidae, Bagridae, Heteropneustidae, Schilbeidae and Siluridae) were recorded, of which 10 species from four families were from Kanyakumari and six species belonging to three families were from Kancheepuram District. In Kancheepuram, the species recorded were Heteropneustes fossilis, Mystus seengtee, M. gulio, M. keletius, M. vittatus and Neotropius atherinoides, and in Kanyakumari the species recorded were Arius arius, Arius subrostratus, Heteropneustes fossilis, Mystus armatus, M. seengtee, M. gulio, M. montanus, M. vittatus, Ompok bimaculatus and O. malabaricus. Among the wetlands, the highest species richness was seen in Puthery and Erachakulam tanks in Kanyakumari and Chembarampakkam Lake in Kancheepuram. The lowest species richness was observed was in Vishnupuram, Thotiode tanks and Mavadi pool of the former district and Vandalur Tank, Kalpakkam Estuary of the latter. Environmental factors such as microhabitat diversity and substrate diversity in the wetlands significantly influenced species richness.

  • Title
    Catfish (Teleostei: Siluriformes) diversity in Karala River of Jalpaiguri District, West Bengal, India
    Type
    Journal Article
    Description
    The diversity of fresh water catfish fauna of the Karala River in Jalpaiguri District of West Bengal was studied from February 2009 to January 2010. A total of seven species belonging to six genera and six families were identified. Bagridae was the dominant family with two representatives, whereas Amblycepitidae, Chacidae, Olyridae, Sisoridae and Siluridae were each represented by single species. Maximum fish diversity was recorded higher in Hakim Para (H =1.266) as compared with DasPara (H =1.218) and Aquiduct (H =1.04). The evenness index at three sampling stations indicates uneven distribution of catfish in this tributary, possibly due to the irregular depth of river, occurrence of submerged vegetation and physicochemical water characteristics.

  • Title
    A new catfish, Hara koladynensis from northeastern India (Siluriformes: Erethistidae)
    Type
    Journal Article
    Description
    A new Erethistid catfish species, Hara koladynensis is described from Koladyne River, Mizoram, India. It is distinguished from its congeners in having rough (vs. smooth or serrated) anterior margin of dorsal spine; shorter pre-anal length (58.5-60.9% SL vs. 63.2-75.2), longer head (36.0-38.3% SL vs. 24.8-34.2%), longer post-adipose distance (18.6-21.9% SL vs. 12.3-18.3), and deeper body (21.9-25.2% SL vs. 11.5-20.9).
