Book of Abstracts. 5th Fisheries Conference & Research Fair 2012. BFRF, Dhaka, Bangladesh. 182 p. iii Foreword Fish and fisheries are inseparable from the culture and heritage of Bangladesh and the fisheries sector plays an important role in the economy in terms of nutrition, income generation, employment and foreign exchange earning of Bangladesh. 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 towards 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 can not be ignored. It is fact that the researchers in this country have been working in isolation in different universities, institutions and other private and NGOs; and there has been a chronic lack of coordination among the researchers as well as between researchers and the extension agencies. These have resulted repetition of research, misuse of scare resources, and thus slow progress in the sector. 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 organizations 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, serve this important sector together, and thus make rapid development through benefiting the end-users of research outputs. It is a great pleasure for me to extend my sincere greetings and felicitations to the members of the BFRF on the occasion of 'Fifth Fisheries Conference and Research Fair 2012' to be hold on 18-19 January 2012 for their commendable contributions to the promotion of science of aquatic natural recourses. We have received about 190 abstracts within a short time of announcement and many were obtained even after closing date. We tried our best to include all the abstracts for oral presentation but given the time available in the two days of the conference, we had to offer place for poster presentation for some abstracts. The forum has made a unique opportunity for us all to listen to the findings of the research carried out hitherto and share and exchange knowledge and ideas to decide future course of actions. Considering the challenges facing our agriculture in general and fisheries in particular due to the environmental factors having negative impacts on fisheries development are by and large man- made intervention in hahitat destruction, disruption of ecology, intensive agriculture, and modern developments, the conference will highlight the present scenario and coping strategies through timely presentation of the keynote paper on ‘Habitat and fish diversity: Bangladesh perspective’. The editorial board has taken a lot of pains and strains in going through and editing the whole lot of abstracts. On behalf of the organizing committee, I would like to thank you all who have given their time to bring out the abstracts book in time and WorldFish Center- Bangladesh and South Asia Office for financial support. I have very best wishes at the beginning of a new year for all the participants in the two days conference and research fair. Prof. Dr. Md.

Further, identifying the sh population with unique shape due to variations in their morphometric characters enable better management of these subunits. Advanced statistical toolkits of morphometry called truss network system and geometric morphometrics have been increasingly used for detecting variations in morphological traits between subunits of sh populations. The present study was therefore carried out with the objective of determining phenotypically distinct units of freshwater sh Systomus sarana collected from geographically isolated locations. Methods: In the present study, 154 specimens of olive barb, S. sarana were collected from four distantly located rivers covering the northern (Ganga), southern (Godavari), central (Narmada), and eastern (Mahanadi) regions of India. Truss-network system and geometric morphometrics have been utilized. Fourteen landmarks were digitized uniformly on each specimen. In the present study, the truss network system yielded size-corrected morphometric characters that were subjected to univariate and multivariate statistical assessment.

Post Graduate College, Mansehra, Pakistan 2Department of Botany, Govt. Post Graduate College, Mansehra, Pakistan 3Department of Zoology, Govt. Degree College, Oghi, Pakistan E-mail: [email protected] Received 12 August 2020; Accepted 20 September 2020; Published 1 December 2020 Abstract Ichthyofaunal composition is the most important and essential biotic component of an aquatic ecosystem. There is worldwide distribution of fresh water fishes. Pakistan is blessed with a diversity of fishes owing to streams, rivers, dams and ocean. In freshwater bodies of the country about 193 fish species were recorded. There are about 30 species of fish which are commercially exploited for good source of proteins and vitamins. The fish marketing has great socio economic value in the country. Unfortunately, fish fauna is declining at alarming rate due to water pollution, over fishing, pesticide use and other anthropogenic activities. Therefore, about 20 percent of fish population is threatened as endangered or extinct. All Mashers are ‘endangered’, notably Tor putitora, which is also included in the Red List Category of International Union for Conservation of Nature (IUCN) as Endangered. Mashers (Tor species) are distributed in Southeast Asian and Himalayan regions including trans-Himalayan countries like Pakistan and India. The heavy flood of July, 2010 resulted in the minimizing of Tor putitora species Khyber Pakhtunkhwa and the fish is now found extinct from river Swat.

    J. Asiat. Soc. Bangladesh, Sci. 46(2): 117-131, December 2020 GENETIC CHARACTERIZATION OF SWAMP EEL OF BANGLADESH THROUGH DNA BARCODING AND RAPD TECHNIQUES MD MINHAZUL ABEDIN, MD MOSTAVI ENAN ESHIK, NUSRAT JAHAN PUNOM, MST. KHADIZA BEGUM AND MOHAMMAD SHAMSUR RAHMAN* Department of Fisheries, University of Dhaka, Dhaka 1000, Bangladesh Abstract The freshwater air-breathing swamp eel Monopterus spp. are native to the freshwater of Bangladesh and throughout the Indian subcontinent. To identify the different swamp eel species and to check the genetic diversity among them, a total of twelve swamp eel specimens were collected from four districts (Tangail, Bogura, Bagerhat and Sylhet) representing the four division of Bangladesh. The extracted DNA from twelve fish samples was amplified by the PCR technique for DNA barcoding and RAPD analysis. Among 12 specimens, 8 specimens showed a 95-100% similarity with M. cuchia species published in the NCBI GenBank database and BOLD system. The studied mct3 (collected from Tangail region), mcs1, mcs2 and mcs3 (collected from Sylhet region) specimens showed about 83% homology with Ophisternon sp. MFIV306-10 as per BLAST search; whereas BOLD private database showed 99% similarity with Ophisternon bengalense (Bengal eel). From the phylogenetic tree analysis, 8 samples were clustered with M. cuchia and 4 samples showed similarity with Ophisternon sp. MFIV306-10 and Ophisternon bengalense _ANGBF45828-19. In RAPD-PCR based analysis, it was found that the maximum genetic distance (1.6094) was observed between mcba2 and mcs3, while between mct1 and mct2, the minimum genetic distance was 0.000. A total of 192 bands, of which 35 were polymorphic with 17.88% polymorphisms among swamp eel species and the size of the amplified DNA fragments ranged from 250 to 1800 bp.

Since the first description of the disease at the end of the 1980s, a considerable amount of research has gone into understanding the mechanisms involved in fish infection, developing reliable diagnostic methods, and control measures, and several comprehensive reviews have been published to date. This review focuses on host–virus interaction and epidemiological aspects, comprising viral distribution and transmission as well as the continuously increasing host range (177 susceptible marine species and epizootic outbreaks reported in 62 of them), with special emphasis on genotypes and the effect of global warming on NNV infection, but also including the latest findings in the NNV life cycle and virulence as well as diagnostic methods and VER disease control. Keywords: nervous necrosis virus (NNV); viral encephalopathy and retinopathy (VER); virus–host interaction; epizootiology; diagnostics; control 1. Introduction Nervous necrosis virus (NNV) is the causative agent of viral encephalopathy and retinopathy (VER), otherwise known as viral nervous necrosis (VNN). The disease was first described at the end of the 1980s in Australia and in the Caribbean [1–3], and has since caused a great deal of mortalities and serious economic losses in a variety of reared marine fish species, but also in freshwater species worldwide.

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.
