Printed in Dhaka, Bangladesh Cover design & photo credit M. Enamul Hoq & M.A.R. Hossain ISBN 978-984-33-6729-7 ii Editorial Fisheries activities has gradually emerged as an important livelihood options for over million of poorer people including full-time and part-time fisher folks, fish farmers, processors and traders. The primary need for animal protein intake for the overwhelming majority has spurred a range of initiatives among actors and institutions forward scientific fisheries management and aquaculture. To support the ongoing development of fisheries and aquaculture, the need for demand led research and generation of sustainable technologies cannot be ignored. It is fact that the researchers in this country have been working in isolation in different institutions, universities and other private and NGO’; and there has been a chronic lack of coordination among the researchers as well as between researchers and the extension agencies. In order to overcome this situation, Bangladesh Fisheries Research Forum (BFRF), a professional organization, was established in 2002 with its mission of breaking the barrier and territoriality among different organization and bring about all the fisheries academics, researchers, extension agencies of both GO and NGOs and other relevant stakeholders under one umbrella so that we can make good use of resources, better serve the sector together, and thus make rapid development through benefiting the end-users of research outputs. It is a great pleasure of us to extend our sincere greeting and felicitations to the members of the BFRF on the occasion of ‘Sixth Biennial Fisheries Conference and Research Fair 2014’ held on 26-27 April 2014 for their commendable contributions to the promotion of science of aquatic natural resources. We have selected about 25 articles from about 190 abstracts presented in 5th Biennial Fisheries Conference and Research Fair 2012. After finalization 16 articles are now presented in Advances in Fisheries Research in Bangladesh: I. In the coming days, other volumes will be published to document and of updated research in fisheries of Bangladesh. We duly acknowledge WorldFish-Bangladesh and South Asia Office for financial support to publish this first volume of the proceedings.

Proc. of 5th Fisheries Conference & Research Fair 2012. 18-19 January 2012, Bangladesh Agricultural Research Council, Dhaka, Bangladesh Fisheries Research Forum, Dhaka, Bangladesh. 246 p. Abstract: Bangladesh is ranked third largest in inland fisheries in Asia behind China and India. The rich aquatic biodiversity of the country has been attributed to the world’s one of the largest wetlands (Bengal Delta) and three large river systems (Brahmaputra, Ganges and Jamuna) that flow from the Himalayan Mountains into the Bay of Bengal. Huge inland fisheries resources supply fish and other aquatic animals and plants to millions of people living in the Delta. Recent acceleration of production from culture fishery (1.73 million tons of fish) in Bangladesh has yet to ease fishing pressure in large rivers and other water bodies. It is expected that the demand for fish will reach over 4 million tons by year 2020. Unfortunately, over-harvesting of fish is likely to continue and exert greater pressure on most of the water bodies. The country will face the biggest risk from global warming in the next 30 years. Because of the shrinkage of the wintering habitats for the fish species due to decrease in groundwater and surface water, tremendous pressure has been exerted on wetlands to convert them to agricultural land. Fishing pressure from an ever-growing population has increased dramatically and has seriously affected the abundance of nearly half of the inland fishes of Bangladesh, particularly many small fishes. Indeed, there may be no place in the world where effects of climate change and other natural/anthropogenic activities on fish biodiversity are more apparent than in Bangladesh. In order to reverse the trend and ensure sustainability of inland

Since the work of J.J. Heckel (1846-1849), the number of valid species has increased significantly and the systematic status of many of the species has changed, and reorganization and updating of the published information has become essential. Here we take the opportunity to provide a new and updated checklist of freshwater fishes of Iran based on literature and taxon occurrence data obtained from natural history and new fish collections. This article lists 288 species in 107 genera, 28 families, 22 orders and 3 classes reported from different Iranian basins. However, presence of 23 reported species in Iranian waters needs confirmation by specimens.

  • Mapping Exercise on Water- Logging in South West of Bangladesh
    MAPPING EXERCISE ON WATER- LOGGING IN SOUTH WEST OF BANGLADESH DRAFT FOR CONSULTATION FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS March 2015 I Preface This report presents the results of a study conducted in 2014 into the factors leading to water logging in the South West region of Bangladesh. It is intended to assist the relevant institutions of the Government of Bangladesh address the underlying causes of water logging. Ultimately, this will be for the benefit of local communities, and of local institutions, and will improve their resilience to the threat of recurring and/or long-lasting flooding. The study is intended not as an end point, but as a starting point for dialogue between the various stakeholders both within and outside government. Following release of this draft report, a number of consultations will be held organized both in Dhaka and in the South West by the study team, to help establish some form of consensus on possible ways forward, and get agreement on the actions needed, the resources required and who should be involved. The work was carried out by FAO as co-chair of the Bangladesh Food Security Cluster, and is also a contribution towards the Government’s Master Plan for the Agricultural development of the Southern Region of the country. This preliminary work was funded by DfID, in association with activities conducted by World Food Programme following the water logging which took place in Satkhira, Khulna and Jessore during late 2013.

Accepted 25 February, 2014 Chaca chaca (Ham.- Buch.) belongs to the family Chacidae. Chaca is the only genus in the family Chacidae and the only species reported from the Indian sub-continent. In India, this fish is available at restricted area. As per the report of NBFGR (2010) and IUCN (2013), a limited population and less number of individuals are found which is pushing this species towards extinction and the status of this fish is endangered. Lack of proper database on the distribution of C. chaca is a hurdle for the fish managers and fish conservators for its study. The present data of C. chaca collected from the various districts of Arunachal Pradesh help to formulate the management plan for in-situ or ex-situ conservation. Key words: Distribution, endangered, Chaca chaca, Arunachal Pradesh, biodiversity, hot spot.

    School of Media, Culture and Creative Arts Department of Social Sciences and International Studies Community Perceptions and Adaptation to Climate Change in Coastal Bangladesh M. Mokhlesur Rahman This thesis is presented for the Degree of Doctor of Philosophy of Curtin University March 2014 i Dedicated to My parents ii Declaration To the best of my knowledge and belief this thesis contains no material previously published by any other person except where due acknowledgement has been made. This thesis contains no material which has been accepted for the award of any other degree or diploma in any university. Signature: ………………………………………………….. Date: ………1 January 2015…………………………………………. iii Acknowledgements The huge task of completing a doctoral thesis obviously demands the support and encouragement of many - from family, friends, and colleagues and more importantly from supervisors. Throughout my journey towards this accomplishment my wife Runa has been the great source of encouragement to fulfill the dream of my father who wanted to see all his children become highly educated but who died when I was in primary school. My mother who died at 101 in October 2013 allowed me to come to Australia in my effort to fulfill my father’s dream. My children were always considerate of the separation from my family for the sake of my study but were curious about what it could bring me at the end. Professor Bob Pokrant, my supervisor, all along has been a guide and often a critic of my quick conclusions on various aspects of the interim research findings. He always encouraged me to be critical while reaching conclusions on issues and taught me that human societies consist of people caught up in complex webs of socio- political relations and diverse meanings, which become ever more complex when we seek to embed those relations and meanings within coupled social ecological systems.
