FRESHWATER ORNAMENTAL FISH DIVERSITY OF TAMIL NADU H. S. MOGALEKARAND P. JAWAHAR Department of Fisheries Biology and Resource Management, Fisheries College and Research Institute, Tamil Nadu Fisheries University, Thoothukudi-628 008, Tamil Nadu (Received:

05.11.2015; Accepted:

15.12.2015)

Freshwater bodies ofTamil Nadu are endowed with diverse ornamental fish fauna comprises of 156 species (including three subspecies) belonging to 68 generas, 27 families and eight orders. Of these, l31 species are endemic to Indian sub-continent, 14 species are endemic to Tamil Nadu and 11 are exotic species. The conservation status of ornamental fish shows that two species belongs to critically endangered category, 16 species endangered, seven species vulnerable, three species near threatened, 102 species least concern, five species data deficient and 21 species have not been evaluated against IUCN criteria. Captive breeding and massive seed ranching are necessary for restoration and replenishment of threatened ornamental fishes, as 16.0 % of ornamental fishes facing the threat. Key words: Freshwater ornamental fish fauna, conservation status, Tamil Nadu.

Updated information on species composition of freshwaterornamental fishes from various localities ofTamil Nadu is documented in this paper.

Tamil Nadu is south-eastern stateofIndia and blessed with varied freshwater fisheries resources due to existence of Eastern Ghats on the North and Western Ghats on the west. Rivers originating from Western Ghats and Eastern Ghats has been conferred with diverse fish germplasm resources (Devi and Indra, 2003; Johnson andArunachalam, 2009; Raghavan et al., 2013; Mogalekar et al., 2015). According to Shaji et al. (2000), 287 species of freshwater fishes have been reported from the Western Ghats ofIndia. Devi and Indra (2003) listed 127 fish species under 26 families and nine orders from Eastern Ghats of India. Ornamental fishes are attractive colourful fishes of various characteristics, which can be retained as pets in aquarium or a garden pool for fun and fancy. These living jewels need not always have to be bright colours; as sometimes their peculiar characteristics such as body colour, morphology or mode of taking food may also add to their attractiveness. Freshwater ornamental fishes of Tamil Nadu were reported by Raj (1916);

Materials and methods The checklist of freshwater ornamental fish fauna from different localities of Tamil Nadu was 27

MOGALEKARANDJAWAHAR endangered while 16 species are endangered, whereas seven species are vulnerable. There are 105 species under the non-threatened category, among which three are near threatened, whereas 102 species belonged to low risk ofleast concern and 21 species have not been evaluated against IUCN criteria.

compiled based on published literature in the form of research articles, monographs, books, species checklists and technical reports. Classification of all taxa follows Talwar and Jhingran (1991), Jayaram (2010) and fishbase (Froese and Pauly, 2013) and based on our own judgement we have adopted the better one. Details on the endemicity or exoticity and Maximum size [TotalLength (TL) or Standard Length (SL)] of all species was obtained by retrieving species level information from the published literature as well as FishBase (Froese and Pauly, 2013). The endemicity or exoticity of all species indicated based on Indian subcontinent. The list of ornamental fishes is prepared based on colouration pattern, shape and maximum size. Information on the conservation status of all taxa in this paper was retrieved from the International Union for Conservation ofNature (IUCN) Red List Categories and criteria (Version 2015.2) downloaded on 29 October 2015 (IUCN, 2015).

Species confmed to the freshwater bodies ofTamil Nadu are Enobarbichthys maeulatus (Day, 1868); Dawkinsia arulius arulius (Jerdon, 1849); Dawkinsia arulius tambraparniei (Silas, 1954); Devario neilgherriensis (Day, 1867); Garra hughi (Silas, 1955); Garra mcclellandi (Jerdon, 1849); Horalabiosa joshuai (Silas, 1954); Horalabiosa palaniensis (Devi and Menon, 1994); Osteobrama neilli (Day, 1873); Osteoehilus nashii (Day, 1869); Pethia sharmai (Menon and Devi, 1993); Puntius mudumalaiensis (Menon and Devi, 1992); Nemaeheilus nilgiriensis (Menon, 1987) and Noemaeheilus triangularis tambaraparniensis (Menon, 1987). Currently many of the endemic, high value ornamental fishes are exploited for commercial purposes from the wild, thus annoying their degree of endangerment.

Results and discussion The name of the species,alongwith theirendemicity or exoticity,maximum size (TL or SL),conservation status as per IUCN criteria and references for their occurrence has been recorded as shown in Table 1.One hundred and fifty six ornamental fish species under eight orders, 27 families and 68 genera were recorded from streams, rivers, canals, reservoirs, irrigation tanks and cold water lakes of Tamil Nadu. Cyprinidae (45.5 %) was the most dominant family represented by 71 species belonging to 22 genera, followed by Nemacheilidae (nine species from two genera), Ambassidae (eight species from three genera) and Cichlidae (seven species from four genera) (Table 1 and 2). Of the 156 species, 14 species are endemic to Tamil Nadu, 131 species are endemic to Indian subcontinent and 11species are exotic and alien. Among the species listed under threatened category, two are critically

The exotic ornamental fish species in Tamil Nadu are Tinea tinea (Linnaeus, 1758); Gambusia affinis (Baird and Girard, 1853); Poeeilia reticulata (Peters, 1859); Cichlasoma trimaculatum (Gunther 1867); Hemichromis bimaculatus (Gill 1862); Oreochromis aureus (Steindachner 1864); Oreochromis mossambicus (Peters, 1852); Osphronemus gourami (Lacepede 1801); Trichopodus trichopterus (Pallas, 1770); Pterygoplichthys disjunctivus (Weber, 1991) and Pterygoplichthys pardalis (Castelnau, 1855) (Table 1). Species such as Barbodes wynaadensis (Day, 1873) and Hemibagrus punetatus (Jerdon, 1849) 28
