A Regional Information System on Fishes from the Western Ghats, India: Its Design, Implementation and Utility Indian Journal of Geo-Marine Science Vol.45(10), October 2016, pp. 1305-1309 A regional information system on fishes from the Western Ghats, India: Its design, implementation and utility Ajey Kumar Pathak*, Shri Prakash Singh, Rajesh Dayal, Uttam Kumar Sarkar & Reeta Chaturvedi ICAR- National Bureau of Fish Genetic Resources, Canal Ring Road, P.O. Dilkusha, Lucknow– 226002, India *[Email: [email protected]] Received 03 July 2014; revised 20 August 2014 Present study discusses design and implementation of an information system for fish biodiversity of Western Ghats region. The system was developed by collating data from published reliable sources and applying Visual Basic language, MSACESS database and ADOBE image technologies for the Windows platform. The system through different search options provides ability to browse taxonomic, distribution, conservation status, morphology, environment and other fishery information of fish species of interest with good quality images. It incorporates information on 373 fish species belonging to 45 families and 141 genus. Of the 373 fish species,141 are endemic to this region and 8 are exotic. This serves as fish checklist resource of this region.

Extreme hydro -climatic events and its consequent shifts in seasonality lead to water scarcity in dry zone aquatic resources such as Vavuniya reservoir, threatening fish species richness and abundance. Weekly filed surveys were made to collect biological, ecological and hydro -climatic data from January, 2013 to July, 2014. Fish species composition a nd abundance in the catch were estimated by using random sampling at the landing site. Clarias brachysoma, Esomus thermoicos and Labeo lankae were the endemic freshwater fish species identified along with 16 indigenous and 8 exotic species. A significantly higher abundance of indigenous species was found in July and August 2013. During these periods, higher rainfall was observed but water level receded to medium level. Peak abundance of Channa striata (July & August 2013 and March & July 2 014), Puntius dorsalis (August 2013 and July 2014) and P.

    Genetic Diversity and Population Structure of the critically endangered freshwater fish species, the Clanwilliam sandfish (Labeo seeberi) By Shaun Francois Lesch Thesis presented in partial fulfilment of the requirements for the degree of Master of Science in the Faculty of Natural Science at Stellenbosch University Supervisor: Dr C.

Slabbert Department of Genetics December 2020 Stellenbosch University https://scholar.sun.ac.za Declaration: By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: December 2020 Copyright © 2020 Stellenbosch University All Rights Reserved i Stellenbosch University https://scholar.sun.ac.za Abstract: Labeo spp. are large freshwater fish found throughout southern Asia, the Middle East and Africa. The genus is characterised by specialised structures around the mouth and lips making it adapted to herbivorous feeding (algae and detritus). Clanwilliam sandfish (Labeo seeberi) was once widespread throughout its natural habitat (Olifants-Doring River system), but significant decreases in population size have seen them become absent in the Olifants River and retreat to the headwaters in the tributaries of the Doring River. Currently sandfish are confined to three populations namely the Oorlogskloof Nature Reserve (OKNR), Rietkuil (Riet) and Bos, with OKNR being the largest of the three and deemed the species sanctuary.

Mintern. Public domain. Available: https://en.wikipedia.org/wiki/Labeo_dussumieri#/media/File:Labeo_dussumieri_Day_Mintern_1 26.jpg. (April 2018). 1 Native Range and Status in the United States Native Range From Raghavan and Ali (2011): “Labeo dussumieri is endemic to southern Kerala [India] and Sri Lanka. In Kerala, it is known from four rivers, Pampa, Achenkovil, Manimala and Meenachil (Kurup 2000), the southern tip of Vembanad Lake (Narayanan et al. 2005; Kurup 2000), and Periyar (Gopalakrishnan et al. 2009). In Sri Lanka they have been recorded from various rivers (Smith 1991) and reservoirs (Amarasinghe and Pitcher 1986, De Silva 1998).” Status in the United States This species has not been reported as introduced or established in the U.S. Means of Introductions in the United States This species has not been reported as introduced or established in the U.S. 1 Remarks From Raghavan and Ali (2011): “Labeo rajasthanicus from Jaisamand Lake in Udaipur has been found to be the same as L. dussumieri and therefore needs to be synonymised (Gopalakrishnan pers. comm.). The record from Alibagh, Maharastra by Jayram (2010) needs verification. The Sri Lankan population needs taxonomic verification as it may be a different species.” From Lal et al. (2015): “The present report redescribes the species L. rajasthanicus based on the specimen collected from its type and other adjoining localities, with confirmation of its taxonomic status as valid species […] Genetic and morphological evidences support the distinction of L.
