Vol. 35, 2016, pp. 7-15 ISSN 1023-6104 http://journals.sfu.ca/bd/index.php/UJZRU © Rajshahi University Zoological Society Present status of fish biodiversity and abundance in Shiba river, Bangladesh D.A. Khanom, T Khatun, M.A.S. Jewel*, M.D. Hossain and M.M. Rahman Department of Fisheries, University of Rajshahi, Rajshahi 6205, Bangladesh Abstract: The study was conducted to investigate the abundance and present status of fish biodiversity in the Shiba river at Tanore Upazila of Rajshahi district, Bangladesh. The study was conducted from November, 2016 to February, 2017. A total of 30 species of fishes were recorded belonging to nine orders, 15 families and 26 genera. Cypriniformes and Siluriformes were the most diversified groups in terms of species. Among 30 species, nine species under the order Cypriniformes, nine species of Siluriformes, five species of Perciformes, two species of Channiformes, two species of Mastacembeliformes, one species of Beloniformes, one species of Clupeiformes, one species of Osteoglossiformes and one species of Decapoda, Crustacea were found. Machrobrachium lamarrei of the family Palaemonidae under Decapoda order was the most dominant species contributing 26.29% of the total catch. In the Shiba river only 6.65% threatened fish species were found, and among them 1.57% were endangered and 4.96% were vulnerable. The mean values of Shannon-Weaver diversity (H), Margalef’s richness (D) and Pielou’s (e) evenness were found as 1.86, 2.22 and 0.74, respectively. Relationship between Shannon-Weaver diversity index (H) and pollution indicates the river as light to moderate polluted.

  • The Conservation Action Plan the Ganges River Dolphin
    THE CONSERVATION ACTION PLAN FOR THE GANGES RIVER DOLPHIN 2010-2020 National Ganga River Basin Authority Ministry of Environment & Forests Government of India Prepared by R. K. Sinha, S. Behera and B. C. Choudhary 2 MINISTER’S FOREWORD I am pleased to introduce the Conservation Action Plan for the Ganges river dolphin (Platanista gangetica gangetica) in the Ganga river basin. The Gangetic Dolphin is one of the last three surviving river dolphin species and we have declared it India's National Aquatic Animal. Its conservation is crucial to the welfare of the Ganga river ecosystem. Just as the Tiger represents the health of the forest and the Snow Leopard represents the health of the mountainous regions, the presence of the Dolphin in a river system signals its good health and biodiversity. This Plan has several important features that will ensure the existence of healthy populations of the Gangetic dolphin in the Ganga river system. First, this action plan proposes a set of detailed surveys to assess the population of the dolphin and the threats it faces. Second, immediate actions for dolphin conservation, such as the creation of protected areas and the restoration of degraded ecosystems, are detailed. Third, community involvement and the mitigation of human-dolphin conflict are proposed as methods that will ensure the long-term survival of the dolphin in the rivers of India. This Action Plan will aid in their conservation and reduce the threats that the Ganges river dolphin faces today. Finally, I would like to thank Dr. R. K. Sinha , Dr. S. K. Behera and Dr.

  • Rivers of Peace: Restructuring India Bangladesh Relations

No part of this book may be reproduced or utilised in any form or by any means, electronic or mechanical, without prior permission from the publisher. Copyright © Strategic Foresight Group 2013 ISBN 978-81-88262-19-9 Design and production by MadderRed Printed at Mail Order Solutions India Pvt. Ltd., Mumbai, India PREFACE At the superficial level, relations between India and Bangladesh seem to be sailing through troubled waters. The failure to sign the Teesta River Agreement is apparently the most visible example of the failure of reason in the relations between the two countries. What is apparent is often not real. Behind the cacophony of critics, the Governments of the two countries have been working diligently to establish sound foundation for constructive relationship between the two countries. There is a positive momentum. There are also difficulties, but they are surmountable. The reason why the Teesta River Agreement has not been signed is that seasonal variations reduce the flow of the river to less than 1 BCM per month during the lean season. This creates difficulties for the mainly agrarian and poor population of the northern districts of West Bengal province in India and the north-western districts of Bangladesh. There is temptation to argue for maximum allocation of the water flow to secure access to water in the lean season.

When we hear the word 'dolphin', what comes to mind is the endearing, intelligent bottlenose dolphin shown in movies and television shows. Though we often make the mistake of believing that there is only one kind of dolphin, there exist over 30 different types of dolphins, and including the river dolphins and porpoises, there are over 40 types of dolphins. To be precise, there are 32 types of oceanic dolphins, 5 species of river dolphins and 6 types of porpoises. Dolphins are important to the ecosystem in the sense that they are apex or top-level predators which control populations of fishes and squids and keep the ecosystem balance. They are the migratory species susceptible to a wide range of threats, including habitat shrinkage in breeding areas, excessive hunting along migration routes, and degradation of their feeding grounds. As a result of international concern over these threats, a UN Convention on the Conservation of Migratory (CMS) Species of Wild Animals, also known as Bonn Convention was adopted in 1979 and entered into force on 1st November 1983, to protect dolphins along their migration routes between their feeding and breeding grounds. Bonn Convention is a unique global advocate of reducing threats to their survival as well as to the ocean and river waters where they live.

    IJSAR, 2(7), 2015; 105-114 International Journal of Sciences & Applied Research www.ijsar.in Decay of the river Baniadaha and its impact on the surrounding environment Sourav Dey* Department of Geography, North Bengal University, India. Correspondence Address: * C/O- Bijoy Dey (Bishu), Bang Chatra Road (Near Five Star Club), Guriahati, Cooch Behar, Pin- 736170, State- West Bengal, India. _____________________________________________________________________________________________ Abstract Cooch Behar district is a land of many perennial rivers. According to the Kochbihar Royal history „Baniadaha‟ river is a distributary of river Torsa and this channel was the navigational route between Bhetaguri and Bangladesh. But at present, like all other rivers of foothills of North Bengal, it is in critical stage of decay. On the basis of field investigation it has been found that the consequent decay of the channel is due mainly to unscientific discharge of domestic waste, construction of unauthorized culverts and bridges across the river, damping of garbage by the encroachers, rapid sedimentation at the off-take point and the embankments construction activities have finally tolled death knell of the „Baniadaha‟. It ultimately turned into a paleo channel for the south-eastern part of Cooch Behar district. At many places the course has totally dried up. The decay of Baniadaha is now considered to be the main cause for water logging and various types of water borne diseases in the surrounding area of this river. The waterway is already gasping for life with the continuous interruption of human beings causing almost total degeneration of the channel. The present study endeavors to examine the different causes and consequences of the decay of the Baniadaha channel from its off-take at Boro Atharokotha (26⁰18‟39.08” N, 89⁰ 25‟22.77” E) from the parent river Torsa to confluence at the Dharla River in Bangladesh (25⁰56‟11.44” N, 89⁰31‟49.77” E) and suggests suitable remedial measures for its revival.
