(eds.) (2010) Inland Fisheries Enhancement and Conservation in Asia. FAO Regional Office for Asia and the Pacific, Bangkok, Thailand. RAP Publication 2010/22, 189 pp. ii FOREWORD Inland capture fisheries provide an important source of food and livelihoods for many people in rural areas. In 2008, inland capture fisheries provided 10.2 million tonnes of fish worldwide (FAO, 2010), which was largely used for direct human consumption. Asia has overwhelmingly contributed to the world’s inland capture fisheries production with a reported total production of 6.8 million tonnes in 2008 (FAO, 2010). The actual contribution of inland capture fisheries, however, is far higher than what is reflected in the above official data. Because of the difficulties involved in collecting data from large numbers of small-scale, scattered and often unregistered fishers, official figures for fish catches tend to be vastly underestimated. Inland fisheries resources provide not only the material basis for maintaining capture fisheries production, but also serve as a reservoir of aquatic biodiversity. However, over the past few decades inland fisheries resources have come under increasing pressure from overfishing, use of destructive fishing gear/methodologies, water engineering projects, pollution and environment changes and have shown a clear declining trend. This has been well demonstrated by the disappearance of some traditionally important fish species and a general reduction in the catch of high valued species. Fisheries resource enhancement and conservation measures have long been adopted in many Asian countries for sustaining capture fish production, conserving aquatic biodiversity, rescuing endangered species, improving environmental conditions and upgrading recreational fisheries by offsetting the adverse impacts of human activities on inland fisheries resources. The contribution of inland fisheries resource enhancement and conservation to sustained inland capture fisheries and conservation of aquatic biodiversity as well as to nutritional security and improved rural livelihoods has been commonly recognized. On the other hand, external interventions to the aquatic ecosystem from fisheries resource enhancement and conservation activities may have had adverse impacts on the ecosystem and wild fish community, especially when such activities are carried out without a strong scientific basis or adequate evaluation and monitoring mechanisms. There is a general lack of comprehensive understanding as to the effectiveness and impacts of current enhancement and conservation activities in the region. This publication is the product of a regional review study on inland fisheries resource enhancement and conservation conducted during 2009-2010. It includes ten country review papers and one regional synthesis report generated from a regional expert workshop. The publication provides the most up-to-date, comprehensive information on inland fisheries resources enhancement and conservation in the region, covering practices, methodologies, operational modalities, impacts, constraints and recommendations for the way forward. The synthesis report provides a regional perspective on inland fisheries resources enhancement and conservation practices in Asia, with special focus on identifying common issues and problems, and recommends actions on improved practices for maximizing benefits to the region. This publication can serve as an important reference for people working in inland fisheries resources management. More importantly, it provides a starting point for anticipated thrusts in promoting better practices of inland fisheries resource enhancement and conservation. Hiroyuki Konuma Assistant Director-General and Regional Representative for Asia and the Pacific iii PREPARATION OF THE DOCUMENT This regional review study is an effort to promote improved inland fisheries management under the Code of Conduct for Responsible Fisheries. It covers ten Asian countries with significant inland capture fisheries, namely Bangladesh, China, India, Indonesia, the Republic of Korea, Myanmar, Nepal, Sri Lanka, Thailand and Viet Nam. The review study was conducted in collaboration with the Network of Aquaculture Centre in Asia-Pacific (NACA). Experts from the ten participating countries prepared a comprehensive review paper for each country during November 2009 to February 2010 following the guidelines jointly developed by the FAO Regional Office for Asia and the Pacific and NACA. A regional expert workshop on inland fisheries resource enhancement and conservation in Asia was subsequently convened by the FAO Regional Office for Asia and the Pacific and NACA from 8 to 11 February 2010 in Pattaya, Thailand. The FAO Regional Office for Asia and the Pacific, NACA, the International Institute for Sustainable Development (IISD) as well as the ten experts from the ten countries who participated in the review study attended. The workshop participants shared experiences and lessons on inland fisheries enhancement and conservation practices across the region, discussed the impacts of inland fisheries resource enhancement and conservation practices, identified the constraints and related problems from a regional perspective and recommended regional collaborative activities to promote improved practices of inland fisheries resource enhancement and conservation. A regional synthesis report was produced as the major output of the workshop. All the country review papers were presented, commented on and reviewed by a panel of experts during the workshop. The authors revised their manuscripts following the suggestions made by the review panel. The regional synthesis report was drafted by Sena De Silva (Director General, Network of Aquaculture Centers in Asia-Pacific, Bangkok, Thailand) based on the workshop discussions and further reviewed. The revised country papers were then reviewed and technically edited by an editorial team, which consisted of Miao Weimin (Aquaculture Officer, FAO Regional Officer for Asia and the Pacific, Bangkok, Thailand), Sena De Silva and Brian Davy (Senior Fellow, International Institute for Sustainable Development, Ottawa, Canada) before the authors finalized their manuscripts. The manuscripts were then reedited by the FAO Regional Office staff for final printing after receiving the final confirmed version from the authors. ACKNOWLEDGEMENTS The completion of the publication was attributable to the joint efforts of all the country review authors and editorial team. Much gratitude is due to the country review authors who made their best efforts in preparing the country papers and showed enormous patience with the many revisions requested of them. Simon Funge-Smith, Senior Fisheries Officer, FAO Regional Office for Asia and the Pacific is gratefully acknowledged for his technical advice and contribution to the expert workshop. Special thanks are due to Pornsuda David for her assistance in the final language editing and in facilitating publication of the document. Finally, Jiansan Jia, Chief of the FAO Aquaculture Management Service is gratefully acknowledged for his technical support. iv TABLE OF CONTENTS Page FOREWORD................................................................................................................................................................................... iii INLAND FISHERIES RESOURCE ENHANCEMENT AND CONSERVATION IN BANGLADESH ................... 1 1.

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. Rhode Co-supervisor: Dr R. 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.

Megalobrama terminalis (Cyprinidae) is en- demic to the large subtropical Pearl River (China) and is a commercially important species. Its population has however been suffering from long-term degradation. In this paper, a seasonal autoregressive integrated mov- ing average (ARIMA) model and redundancy analysis (RDA) were proposed to predict larval abundance and its influence, using larva data collected every 2 days from 2006 to 2013. The ARIMA model provided good forecasting performance and estimated that the population trends will follow a relatively stable cycling trend in the near future. The cross-correlation function model further identified that discharge acted as a trigger for population growth; the effect of discharge on the number of larvae will last at least 5 days.

Circular No. 65 9^ RUSSIAN-ENGLISH GLOSSARY OF NAMES OF AQUATIC ORGANISMS AND OTHER BIOLOGICAL AND RELATED TERMS ^5, Compiled by W. E. Ricker Fisheries Research Board of Canada Nanaimo, B.C. August, 1962 FOREWORD This short Russian-English glossary is meant to be of assistance in translating scientific articles in the fields of aquatic biology and the study of fishes and fisheries. j^ Definitions have been obtained from a variety of sources. For the names of fishes, the text volume of "Commercial Fishes of the USSR" provided English equivalents of many Russian names. Others were found in Berg's "Freshwater Fishes", and in works by Nikolsky (1954), Galkin (1958), Borisov and Ovsiannikov (1958), Martinsen (1959), and others. The kinds of fishes most emphasized are the larger species, especially those which are of importance as food fishes in the USSR, hence likely to be encountered in routine translating. However, names of a number of important commercial species in other parts of the world have been taken from Martinsen's list. For species for which no recognized English name was discovered, I have usually given either a transliteration or a translation of the Russian name; these are put in quotation marks to distinguish them from recognized English names.

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.
