3 Resource abundance and survival of indigenous omamental fishes of Central Kerala with emphasis on handling and packing stress in Puntius filamentosus (Valenciennes) 2.1. Introduction The State of Kerala is located at the southern extremity of the Indian subcontinent, along the shores of Arabian sea covering a distance of 580 km with Karnataka state on the north and north east and Tami! Nadu state on the east and south. Lying between 8 17'30" and 12 47'40" north latitude and 74 51' and 7r24" east latitude, the state is spread over an area of km 2. One of the striking features of Kerala is the majestic presence of Western Ghats all along its stretch influencing the physiographic and eco-climatic factors of the state (Gopi, 2000), in addition to supporting very rich and diversified biological resources. The water resource of the state covers network of brackish water lakes and estuaries with an area of 2,43,000 hectare, 44 rivers flowing to a total length of 3200 Km, 30 reservoirs having a water spread of 30,000 hectare, small tanks and ponds covering an area of 6,000 hectare. Table 2.1 gives the list of rivers flowing through Kerala along with its total length and catchments area. The watershed of these entire 44 rivers, of which 41 are flowing westwards and 3 are flowing eastwards, are in the Western Ghats. Out of the 30 dams (Table 2.2), nine each were constructed across the various tributaries of Bharathapuzha and Periyar. As a part of Janakeeya Malsyakrishi program of Fisheries department of Kerala, the inland water bodies of the state were analysed and table 2.3 gives the district wise details of water bodies identified for this programme. Freshwater fishes of Western Ghats have attracted the attention of ichthyologists all over the world due to their rich diversity and high degree of endemism. Of the 486 primary freshwater fishes known from India, 287 species are found in Western Ghats (Shaji et al., 2000). Information on the fish fauna of the region is available in the compilations of Day (1878, 1889); Jayaram (1981,1999) and Talwar and Jhingran (1991). Most of the studies on Western Ghat fishes mainly focus on documentation of species (Silas, Diversity and distribution of ornamental fishes of Keraia 34

However a few have also focused on habitat characteristics (Arun, 1997). The investigations of freshwater fish fauna of Kerala are those of Day (1865, 1878,1889); Pillai (1929); John (1936); Hora and Law (1941); Silas (1951a, b); Remadevi and Indra (1986); Pethiyagoda and Kottelat (1994); Shaji and Easa (1995a, b, c); Shaji et al. (1995); Menon and Jacob (1996); Shaji (1998); Manimekalan and Das (1998); Thomas et al. (1998a, b, c, 1999); Ajithkumar et al. (1999); Biju et al. (1999a, b, 2000); Ramachandran (2001, 2002); Ramachandran et al. (2001, 2002); Kurup (2002) and Kurup et al. (2002, 2004). In this chapter an attempt is made to prepare a consolidated list of freshwater fishes of Kerala by compiling the information from past literature and survey undertaken during the study period. Though the previous attempts have contributed to the knowledge on fish resources, they were not directly useful for judicious utilisation of native fauna for economic benefit of the state. Ornamental fish industry in the state is fully dependent on exotic species. This state of affair is mainly due to the lack of information on the ornamental fishes, their breeding and rearing technologies in the inland waters of the state. No concerted attempt has so far been made to list out the indigenous ornamental fishes in the state considering their potential as a commodity in the international market. Shaji and Easa (2000) published a list of 41 ornamental fishes for breeding and rearing in the aquarium. A list of 13 ornamental fishes has been reported by Arunachalam et al. (2000a). Arunachalam et al. (2000b) listed out 35 species of ornamentals from Western Ghats of south India, out of which 27 were found to inhabit the rivers of Kerala. Ramachandran et al. (2002) made a detailed account of 106 ornamental fishes available in Kerala. The authors created a website ( of indigenous ornamental fishes of Kerala for the benefit of the industry. Jameela Beevi and Ramachandran (2002) had given a brief account of native ornamental fishes of waterbodies of Ernakulam district. Kurup et al. (2004) published a list of 106 ornamental fishes based on his studies on the biodiversity status of fishes inhabiting rivers of Kerala.

7 Resource abundance and survival of indigenous ornamental fishes of Central Kerala with emphasis on handling and packing stress in Puntius filamenlosus (Valenciennes) updated information about the ornamental fishes available in Kerala is still lacking. Therefore this attempt is to bring more accurate and authentic information on the freshwater ornamental fishes available in the fourteen major river systems of Kerala with a focus on the development of the ornamental fish industry Materials and Methods A compilation of available reports and literature regarding the studies on the freshwater fishes of Kerala up to the year 2004 was made to generate a complete database on the freshwater fishes of the state. This study was carried out as part of the research project entitled" Indigenous ornamental fishes of Kerala for the development of markets in India and Abroad" funded by Marine Product Export Development Authority and implemented in the School of Industrial Fisheries, Cochin University of Science and Technology in the year As part of the project work, a preliminary survey was conducted in 20 river systems to find out the diversity and distribution of freshwater fishes of Kerala. 14 river systems viz., Bharathapuzha Pamba, Periyar, Muvattupuzha, Meenachil, Manimala, Achencoil, Kallada, Neyyar, Chalakudy, Chaliyar, Kabbini, Valapattanam and Chandragiri were selected for sampling and monitoring. Fig. 2.1 illustrates the rivers of Kerala. Survey was based on the information available in previous literature regarding the distribution of the fish species, available water spread and other accessibility criteria. Along the 14 rivers, 120 locations were selected for regular sampling and monitoring (Appendix. 1 ). Each river system was categorised into several divisions including upper, middle and down stream areas and sampling locations were fixed with a distance of approximate 15 kilometres for periodic assessment of the fish distribution. At each sampling station an approximate 200 m area were surveyed to get a clear picture on the fish diversity and its distribution. Studies were mainly done in pre monsoon and post monsoon seasons. However, some collections were made during monsoon periods. Sampling was done by using various fishing methods Diversity and distjibution of ornamental fishes of Kerala 36

9 Resource abundance and survival of indigenous ornamental fishes of Central Kerala with emphasis on handling and packing stress in Puntius filamentosus (Valenciennes) like cast nets (10 mm, 16 mm, and 18 mm), gill nets (30 mm, 38 mm, 64 mm and 78 mm), scoop nets, dragnets and traditional fishing practices. The relative abundance of the fishes in the 14 rivers was assessed based on their occurrence. Fishes enjoying a distribution in more than 12 river systems were considered as very common and those found in 6-12 rivers were treated as common species. Fishes distributed only in 3-6 rivers systems were treated as rare and those fishes having a restricted distribution in less than three rivers were classified as very rare. Fishes col/ected from each sampling locations were preserved in 10% formaldehyde and brought to the laboratory for Identification of the species. Standard references such as Day (1958); Talwar and Jhingran (1991); Jayaram (1981, 1999); Dutta Munshi and Srivastava (1988) and Menon (1999) were used for the classification and identification. Confirmation of the systematic position of the doubtful species were done by Zoological Survey of India. Live samples were also brought to the lab and maintained in aquarium conditions in the laboratory to assess the aesthetic appeal and performance. Essential Information regarding the indigenous ornamental fishes such as trade name, local name, appearance, current distribution and trade status were collected. Fishes were categorised into three groups such a.s indigenous ornamental fish, exotic ornamentals and food fish based on the information from literature as well as local fisher folk, ornamental fish traders and Marine Products Export Development Authority, Cochin, India Results A consolidated list of freshwater fishes recorded so far from Kerala state and their distribution in various waterbodies including, status as per the IUCN criteria and extent of endemism are given in the table 2.4. A database of 175 freshwater fishes belonging to 72 Genera of 28 families and 11 orders was created based on the secondary data. According to this the most represented order was Cypriniformes followed by Perciformes and Diversit)' and distribution of ornamental fishes of Kerala 37

17 Resource abundance and survival of indigenous ornamental fishes of Central Kerala with emphasis on handling and packing stress in Punlius filameniosus (Valenciennes) Siluriformes. The family with maximum number of representatives was Cyprinidae. Most abundant genus was Puntius followed by Mystus and Nemacheilus. As per the classification based on the IUCN criteria (Biju et al., 2000, Kurup et al., 2004), out of the total 175 species, 50% were under the threatened category, 35% non-threatened, 13% data deficient category and the rest 2% were introduced into the water bodies of Kerala (Fig.2.2). It was also found out that 23 species were extremely endemic to Kerala of which 9 are exclusively distributed in the Western Ghat region of Kerala. 33 fishes were endemic in nature to the rest of the areas of Western Ghats, 6 are endemic to India. Exotic and species transplanted were 2 and 4 respectively. The table 2.5 depicts the list of freshwater fishes collected and identified form the 14 rivers of Kerala during the period of January 2000 to December 2002, along with the details regarding distribution of the species (based on the occurrence) and commercial importance. 114 species belonging to 26 families, 10 orders and 57 genera were collected from 14 rivers during the present study. Highest number of species (56 species) were from the family Cyprinidae. This was followed by family Bagridae with 10 and Balitoridae with 8 species. Ambassidae was represented by 5 species followed by Channidae with 3 species included in the. Dominant genus was. Puntius with 17 species. Genus Mystus included 7 species. Other prominent genera were Gonoproktopterus, and Garra with 5 species each followed by Barilius with 4 species. The survey results point out that fish diversity was maximum in Periyar river system, which contained 68 species (Table.2.5). 63 species were recorded from Bharathapuzha followed by 60 species from Chalakudy river. Piscean diversity of other rivers were as follows. Chaliyar and its tributaries (58 species), Pamba (57 species), Muvattupuzha (57 species), Kabbini river (56 species), Chandragiri (50 species), Achencoil (54 species), Manimala (46 species) and Meenachil 44 species).

The presence of these exotic fishes especially Cyprinus carpio, Oreochromis mossambica and Catla cat/a were noted from most of the major reservoirs. Megalops cyprinoides and Mystus gulio are the two migratory species collected during the survey. They were very common in the brackish water areas but occasionally found in the freshwater areas. Their distribution was noted only from the down stream areas in the present study. Out of the 114 species collected, 95 species (84%) were indigenous ornamental fishes. Food fishes were 16 in number (14%), including both indigenous and exotic cultivable fishes (Fig. 2.3). The rest 3 (2%) were ornamental fishes, which have now established themselves in our water bodies. The present status of ornamental fishes in the international fish trade is depicted in Fig % of the ornamental fishes are popularised in the international ornamental fish market, whereas the remaining 44% are not popular but has potential to be popular in the international ornamental fish industry if properly introduced and positioned.

The species such as Anabas testudineus, Awaous gutum, Bhavania australis, Gonoproktopterus curmuca, Heteropneustes fossilis, Horabagrus brachysoma, Macrognathus guentheri, Mystus ma/abaricus, M. vittatus, Nandus nandus, Nemacheilus guentheri, Notopterus notopterus, Parambassis dayi, P. thomassi, Pristolepis marginata, Puntius denisonii, P. sarana subnasutus and Tetraodon travancoricus were the 'common' ornamentals observed during the survey, which formed 18.9% of the total. 25.3% were 'rare' ornamental fishes which included Amblypharyngodon microlepis, Anguil/a bengalensis benga/ensis, Barilius bendelisis, B. canarensis, Batasio travancoria, Chanda nama, Channa orientalis, Garra mcclellandi, G. surendranathinii, Gonoproktopterus thomassi, Horadandia attukorali, Microphis cuncalus, Mystus cavasius, M. oculatus, Nemacheilus semiarmatus, Ompok malabaricus, Osteobrama bakeri, Osteochilichthys nashii, Puntius conchonius, P. cho/a, P. dorsalis P. jerdoni, Sicyopterus griseus and Wallago attu. 25.3% of the indigenous ornamental fishes were observed to be 'very rare'. Achanthocobitis moreh, Aplochei/us blockii, Brachydanio re rio, Chanda ranga, Chela dadiburjorj, C. fasciata, C. labuca, Esomus danricus, Garra gotyla stenorhynchus, G. hugi, Glyptothorax madraspatanum, G. annandalei, Horabagrus nigricol/aris, Labeo nigrescens, Macrognathus aral, Mystus montanus, Nemacheilus den/sonii denisonii, Neolissochilus wynadensis, Puntius arulius, P. bimaculatus, P. melanos.tigma, P. parrah, P. sophore, Travancoria eiongata and T. jonesi were the 'very rare' species found during the present study. The status of indigenous ornamental fishes as per the classification based on IUCN criteria were extracted from the literature available on the status of freshwater fishes of Kerala (8iju et al., 2000 and Kurup et al., 2004) is given in the Fig % of the total ornamental fishes came under the threatened category and the rest 53.7% under the non-threatened category. 3% of the fishes were listed as critically endangered, 21 % as endangered and 22% as vulnerable. 18% of ornamental fishes fell under Diversity and distribution of ornamental fishes of Kerala 40

28 Resource abundance and survival of indigenous ornamental fishes of Central Kerala with emphasis on handling and packing stress in Puntius filamentosus (Valenciennes) low risk near threatened category and 30% fell under low risk least concern category. The rest 6% were considered as data deficient. On comparison of the results of the present survey with that of the past literature, it becomes obvious that some species noted by the earlier workers were not recorded during the present survey. Table lists those species which are recorded by earlier investigators, with river source, but not observed during the present study. 63 species out of the 175 species, reported by the earlier workers were not obtained during the present survey. Of these 63 species, absence of three is justifiable because they were reported from other river sources and backwaters of Kerala, which are not included in the present survey. The stream originating from Chokkenpetty and reaching the Periyar lake covering vast area of Periyar tiger reserve also could not be included in the survey due to the practical difficulty of regular sampling and restriction from forest departments. This may be one of the reasons for the absence of rare end endemic species like Lepidopygopsis typus, Garra periyarensis, Nemacheilus menoni, N. keralensis, etc. which were reported by previous investigators from the tiger reserve area above Thannikkudy. Other reasons for the disappearance of the fishes may be indiscriminate fishing practices, mass poisoning pollutions, etc. (Kurup, 2002; Kurup et al., 2004). Other disparities were also noticed in the distribution many species between the secondary and primary data. Significant among them was the presence of exotic species from the two new localities ie, green sword tail, Xiphophorus helleri from Azhutha river, Peermedu, a tributary to Manimala river and common platy, Xiphophorus maculatus, obselved from the Mattupetty reselvoir of Periyar river. Labeo nigrescens hitherto reported only from Perumthenaruvi, Pamba river was found to be distributed in obselved Vettilappara and Athirapilly locations of Chalakudy river as well as Parisakuthu and Pooyamkutty locations of Periyar during the sulvey.

Remarks: Mainly seen in the low and mid land areas. Common size is 30cms. Juveniles are most preferred as ornamental fishes. IUCN status: Non- threatened (LR-Ic) (Biju et al., 2000). Kerala has optimum conditions for the development of an ornamental fish industry. But adequate scientific knowledge about the resources for the use of public are still lacking. The knowledge about the indigenous ornamental fish resources is expected to contribute substantial improvement in the growth of the ornamental fish industry of Kerala. At the same time, the increasing concern of scientists about the resource depletion is becoming one of the crucial limiting factors for the development of the industry, as the over exploitation is expected to create species endangerment in the future. One of the possible solutions to overcome this situation is the development of captive breeding technique for the commercial species. Several research institutions have taken initiatives to perfect the captive breeding technology of many species, giving highest priority to the endangered fishes, with the financial support from Government of India. As per the available information, captive breeding technology for 27 Indigenous ornamental fishes has been perfected so far. This covers about 28.42% of the total ornamental species available in Kerala. The traders also take effort to breed some popular ornamental species, as they are aware about the environmental problem associated with the wild fish harvesting. These achievements are expected to facilitate the expansion of the industry in the coming years. Diversity and distribution of ornamental fishes of Kerala 78
