Proceedings of a Workshop on the Development of a Genetic Improvement Program for African Catfish Clarias Gariepinus Proceedings of a Workshop on the Development of a Genetic Improvement Program for African Catfish African catfish (Clarias gariepinus) production has gained considerable importance in a number of African countries. The species has several desirable attributes that make it attractive for aquaculture development. It is easy to reproduce, it does not require specialized feed, it tolerates high stocking densities, it accepts artificial feed, it tolerates poor water quality, and very importantly, it is highly sought after in local markets and economically viable in pond production systems. The species is endemic to Africa. In 2007 the WorldFish Center organized a workshop in Accra, Ghana, hosted by the Water Research Institute, to review the status of the catfish industry in Africa and develop recommendations on how best to approach the issue of genetic improvement programs. The results of the workshop are presented in this volume.

  • Freshwater Fish Survey of Homadola-Nakiyadeniya Estates, Sri Lanka
    FRESHWATER FISH SURVEY OF HOMADOLA-NAKIYADENIYA ESTATES, SRI LANKA. Prepared by Hiranya Sudasinghe BSc. (Hons) Zoology, M.Phil. reading (University of Peradeniya) INTRODUCTION The diversity of freshwater fishes in Sri Lanka is remarkably high, with a total of 93 indigenous fishes being recorded from inland waters, out of which 53 are considered to be endemic (MOE, 2012; Batuwita et al., 2013). Out of these, 21 are listed as Critically Endangered, 19 as Endangered and five as Vulnerable in the National Red List (MOE, 2012). In addition, several new species of freshwater fishes have been discovered in the recent past which have not yet been evaluated for Red Listing (Batuwita et al., 2017; Sudasinghe 2017; Sudasinghe & Meegaskumbura, 2016; Sudasinghe et al., 2016). Out of the 22 families that represent the Sri Lankan freshwater ichthyofauna, the family Cyprinidae dominates, representing about 50% of the species, followed by the families Gobiidae, Channidae and Bagridae, which represent seven, five and four species, respectively. The remainder of the other families are each represented in Sri Lanka by three species or less. Four major ichthyological zones, viz. Southwestern zone, Mahaweli zone, Dry zone and the Transition zone were identified by Senanayake and Moyle (1982) based on the distribution and the endemism of the fish. The Southwestern zone shows the greatest diversity, followed by the Mahaweli zone, with the least diversity observed in the Dry zone. About 60% of the freshwater fishes occur both in the dry and the wet zones of the island while the rest are more or less restricted to the wet zone. Of the endemic fishes, more than 60% are restricted to the wet zone of the island while about 30% occur in both the dry and the wet zones.

  • Impact of Fishing with Tephrosia Candida (Fabaceae) on Diversity
    Impact of fishing with Tephrosia candida (Fabaceae) on diversity and abundance of fish in the streams at the boundary of Sinharaja Man and Biosphere Forest Reserve, Sri Lanka Udaya Priyantha Kankanamge Epa & Chamari Ruvandika Waniga Chinthamanie Mohotti Department of Zoology & Environmental Management, Faculty of Science, University of Kelaniya, Kelaniya 11600, Sri Lanka; [email protected], [email protected] Received 07-V-2015. Corrected 04-III-2016. Accepted 31-III-2016. Abstract: Local communities in some Asian, African and American countries, use plant toxins in fish poisoning for fishing activities; however, the effects of this practice on the particular wild fish assemblages is unknown. This study was conducted with the aim to investigate the effects of fish poisoning using Tephrosia candida, on freshwater fish diversity and abundance in streams at the boundary of the World Natural Heritage site, Sinharaja Forest Reserve, Sri Lanka. A total of seven field trips were undertaken on a bimonthly basis, from May 2013 to June 2014. We surveyed five streams with similar environmental and climatological conditions at the boundary of Sinharaja forest. We selected three streams with active fish poisoning practices as treatments, and two streams with no fish poisoning as controls. Physico-chemical parameters and flow rate of water in selected streams were also measured at bimonthly intervals. Fish were sampled by electrofishing and nets in three randomly selected confined locations (6 x 2 m stretch) along every stream. Fish species were identified, their abundances were recorded, and Shannon-Weiner diversity index was calculated for each stream. Streams were clustered based on the Bray-Curtis similarity matrix for fish composition and abundance.

  • Vertebrate Fauna of Morankanda-Mukalana Secondary Forest Patch in Sri Lanka: a Checklist Reported from 2004-2008 Survey
    RUHUNA JOURNAL OF SCIENCE Vol 6: 21- 41, June 2015 ISSN: 1800-279X Faculty of Science University of Ruhuna Vertebrate fauna of Morankanda-Mukalana secondary forest patch in Sri Lanka: A checklist reported from 2004-2008 survey Hareschandra Bandula Jayaneththi Young Zoologists’ Association of Sri Lanka, National Zoological Gardens, Sri Lanka Correspondence: [email protected] Received: 26th February 2015, Revised: 29th June 2015, Accepted: 30th June 2015 Abstract. Morankanda-Mukalana is a fragmented forest patch which is located in the Galle district, Southern wet zone of Sri Lanka. Biogeography of the Morankanda is noteworthy because it is located in the middle of the transition area of forest reserves or proposed forest reserves, which includes Beraliya Mukalana. This basic field survey was carried out upon the request made by Morakanda Estate management to define vertebrate checklist in the related area with the aim of starting analogue forestry as a future practice. During the study, a total of nine freshwater fish species were recorded (including four endemics), together with 14 species of amphibians (8 endemics), 43 reptile species (20 tetrapods and 23 serpentoids incl. 16 endemics), and 26 mammals (3 endemics). Avifauna comprised of 112 species (9 migrants) with 12 endemic birds (including proposed endemics). The high vertebrate faunal diversity revealed in this study paved the way for the estate management to change their plantation practice by maintaining partially analogue forestry following conservation practices which will positively affect to improve the status of wild fauna. Keywords. Agro-ecosystem, analogue forestry, endemic fauna, rain forests, vertebrate checklist. 1 Introduction Sri Lanka is an island off the southern tip of India, and is a biodiversity hotspot.

It originates from the central hills and flows through a diverse array of landscapes, including some of the most urbanized regions and intensive land uses. Kelani River suffers a multitude of environmental issues: illegal water diversions and extractions, impoundment for hydroelectricity generation, and pollution, mostly from agrochemicals, urban runoff, industrial discharges, and domestic waste. Moreover, loss of riparian forest cover, sand-mining, and unplanned development in floodplains have accentuated the environmental damage. In this study, based on Kelani River basin, we reviewed the status of biodiversity, threats encountered, conservation challenges, and provided guidance for science-based conservation planning. Kelani River basin is high in biodiversity and endemism, which includes 60 freshwater fish species of which 30 are endemic.

Box 5050, Saint John, New Brunswick, E2L 4L5, Canada 2Institute of Fundamental Studies, Hanthana Road, Kandy 20000, Sri Lanka 3Permanent Address: Office of the Registrar of Pesticides, Department of Agriculture, 1056, Getambe, P.O. Box 49, Peradeniya 20400, Sri Lanka Abstract: Patterns of fish community composition in the Mahaweli ichthyological region of Sri Lanka were examined in agricultural tributaries of the Uma-oya catchment of the upper Mahaweli River in comparison to more pristine streams in a nature reserve in the Amban-ganga catchment. The Uma-oya catchment shows characteristics commonly observed in extensive agricultural exploitation such as impaired water quality and altered riparian vegetation. The most abundant fish species in the two regions were Garra ceylonensis, Devario malabaricus, and Rasbora daniconius, although their relative abundance differed between sites. G. ceylonensis and Neomacheilus notostigma were the only endemic fish species in common but the latter has been extremely depauperate. Endemism is higher in the reference sites (62.5%) than agricultural sites (ca. 25%); some of the reference streams showed greater diversity with unique fish species and a few species that have not been recorded previously in the catchment. The ichthyofaunal similarity between two catchments was 39% and fish species diversity was negatively correlated with stream gradients (Pearson correlation (-0.630); r2 = 39.6% p = 0.028).

SUNDARABARATHY3 I Post Graduate Institute ofAgriculture, University ofPeradeniya 2Department ofAnimal Science , Faculty ofAgriculture. University ofPeradeniya "Department ofZoology, Faculty ofScience. University ofRajarata Walking catfish (Clarias brachysoma), a highly threatened endemic freshwater fish, is found widely distributed throughout the country. In this study, specimens of catfish were collected from Kotmale Oya of the Mahaweli River to understand their qualitative and quantitative characteristics. This knowledge could be useful to breed them and nurture the fry and fingerlings under captive conditions. It was observed that captured fish could be easily domesticated after different time periods, when they completely abandon feeding. However, young fish took longer time (nearly 1-2 month/s) than adults (about 1-2 weeks) to adapt to the artificial environment After acclimatizing they started predating on wild guppy and crustaceans. Condition Factor of the fish collected from the natural habitat (0.0088 ± 0.0002) was significantly higher than the laboratory reared fish (0.0073 ± 0.0002), mainly due to the prolonged acclimatizing period, where they resist feeding completely and depend on their body storage. This indicates the need to develop improved feed rations and/or feeds to achieve an appropriate Condition Factor for breeding them under laboratory conditions. Gill rackers in catfish were short and stumpy. The number of gill rackers on the l SI gill arch was 18 with much grown gill filaments .

  • Prehistoric Fishing Practices in Sri Lanka
    1 Fishing Practices in Prehistoric Sri Lanka Wasantha S Weliange Postgraduate Institute of Archaeology, 407, Bauddhaloka Mawatha, Colombo 7, Sri Lanka Corresponding Author; [email protected] Abstract A considerable amount of information on prehistoric culture has been gathered from various areas in Sri Lanka. Batadomba Lena Cave in Kuruwita and Bundala in the southern Sri Lanka are two prehistoric sites which are as old as 40,000 years and 125,000 years respectively. Several caves in the wet, dry and intermediate zones were excavated during the last 70 years and a large amount of evidence has been discovered from these sites, which could be used to explain the prehistoric culture in Sri Lanka. Archaeo-faunal evidence helped to describe the prehistoric man not only as a hunter gatherer but also as a fisherman in the floodplains, rivers and streams. The simplest form of fishing tools made out of bones were discovered from many prehistoric settlements in Sri Lanka, indicating that there existed a gradual development of fishing technique and related activities. In this synthesis, an attempt is made to discuss the probable fishing techniques practised in the prehistoric times in habitats such as flood plains, rivers and streams. In this regard, information on, 1) traditional fishing practices of native Sri Lankans; 2) fish guilds that are popular in the dietary habits of Sri Lankans; 3) remains of fishes discovered from the prehistoric settlements; and 4) ecology of freshwater fishes was evaluated. Thirteen food-fish guilds were recognized in the dietary culture of Sri Lanka and were ranked considering the relative importance in the human diet.
