Muzammel Hossain* and Mohammad Abdul Baki Abstract The present studies the molluscan fauna from twelve sampling stations within two sites of River Brahmaputra in Mymensingh, Bangladesh. Survey was carried out from December 2011 Mohammad Abdul Baki to November 2012. During survey period we have collected mollusca by hand packing from Assistant Professor, the study area and identified a total of 15 species. Altogether 15 species (10 gastropod and 5 Department of Zoology, Jagannath University, bivalve species) were recorded during the study period. Among gastropoda Melanoides Dhaka-1100, Bangladesh. tuberculata (Muller), Indoplanorbis exustus (Deshayes) and Bellamya begalensis were most dominant species recorded from all stations and in Bivalve specie Lamellidens marginalis were found at ten stations out of twelve. Three types of habitat (Muddy, Sandy and low vegetation) Md. Muzammel Hossain also observed in the River. The study revealed that the molluscan community could be Department of Zoology, explored for possible use as biomonitors in the River Brahmaputra.

Introduction Freshwater mollusca populations have been declining for decades and are among the most seriously impacted aquatic animal’s worldwide [1, 13]. Most freshwater mollusca prefer well- oxygenated water and a constant flow of shallow water [3, 7].

These cercariae have a stylet and thus belong to the Xiphidiata. However, such combination of characters as extremely large body size and I-shaped excretory bladder has not been found before in any other xiphidiocercariae. We obtained COI, ITS1, 5.8S + ITS2, and 28S rDNA sequences for C. cattieni 1. The latter allowed us to specify the phylogenetic position of the discovered cercariae: C. cattieni 1 falls within the superfamily Microphalloidea and is most closely grouped to Pachypsolus

  • 1 Current and Selected Bibliographies on Benthic
    1 ================================================================================== CURRENT AND SELECTED BIBLIOGRAPHIES ON BENTHIC BIOLOGY – 2014 [published in May 2016] -------------------------------------------------------------------------------------------------------------------------------------------- FOREWORD. “Current and Selected Bibliographies on Benthic Biology” is published annually for the members of the Society for Freshwater Science (SFS) (formerly, the Midwest Benthological Society [MBS, 1953-1975] then the North American Benthological Society [NABS, 1975-2011]). This compilation summarizes titles of articles published during the year (2014). Additionally, pertinent titles of articles published prior to 2014 also have been included if they had not been cited in previous reviews, or to correct errors in previous annual bibliographies, and authors of several sections have also included citations for recent (2015–) publications. I extend my appreciation to past and present members of the MBS, NABS and SFS Literature Review and Publications Committees and the Society presidents and treasurer Mike Swift for their support (including some funds to compensate hourly assistance to Wetzel during the editing of literature contributions from section compilers), to librarians Elizabeth Wohlgemuth (Illinois Natural History Survey) and Susan Braxton (Prairie Research Institute) for their assistance in accessing journals, other publications, bibliographic search engines and abstracting resources, and rare publications critical to the

Email address: [email protected] Received November 3, 2016; Accepted July 9, 2017 Abstract Freshwater snail genus Brotia is susceptible to trematode infections. In this study, Brotia spp. were collected from 61 localities in Thailand during 2004-2009 and 2013-2015 (to collect those in all localities distributed in Thailand, they have to be collected in two time frames). The samples were collected by hand picking and scooping methods based on counts per unit of time. A total of 13,394 snails were collected and identified into 16 species. They were B. armata, B. binodosa, B. citrina, B. costula, B. dautzenbergiana, B. henriettae, B. insolita, B. manningi, B. microsculpta, B. pagodula, B. paludiformis, B. peninsularis, B. pseudosulcospira, B. solemiana, B. subgloriosa, and B. wykoffi. Cercariae were investigated using shedding and crushing methods. Three species of Brotia had found the cercarial infections, they were B. costula, B. dautzenbergiana, and B. wykoffi. The overall infection rate was 0.20% (27/13,394). The cercariae were categorized into two types and three species. The first type was Xiphidiocercariae with one species,Loxogenoides bicolor Kaw, 1945. It was found in those three species of infected snails. The infection rate was 0.18% (24/13,394).

Tujuan dari penelitian ini untuk menganalisis profil hemosit Susuh Kura (Sulcospira testudinaria) di Kawasan Konservasi Badher Bank dan menganalisis kualitas air dalam rangka evaluasi kualitas perairan. Metode penelitian yang digunakan adalah deskriptif dengan teknik survei. Sampel yang diambil adalah sampel kualitas air dan susuh kura di 4 stasiun. Berdasakan hasil pengukuran kualitas air didapatkan hasil, suhu berkisar 27,3-30,7°C, kecepatan arus berkisar 0,6-1 m/s, kecerahan berkisar 5-8,7 cm, TSS(Total Suspended Solid) berkisar 11-46 mg/l, pH berkisar 7,31-7,60, DO (Dissolved Oxygen) berkisar 3,6-5,1 mg/l dengan ambang batas minimal 4 mg/l, amoniak berkisar 0,043-0,246 mg/l. Hasil kualitas air, hanya amoniak yang melebihi ambang batas. Hasil pengamatan THC didapatkan nilai antara 28x104 – 96x104 sel/ml. Analisis pada DHC didapatkan hyalinosit berkisar antara 16,28-75,49%, Semi granulosit berkisar antara 3,13-23,53% dan granulosit berkisar antara 8,82-72,09%. Hasil analisis CCA menunjukkan THC, hyalinosit dan semi granulosit dipengaruhi 7 parameter dengan konsentrasi sedang.

  • Ốc Nước Ngọt Ở Việt Nam: Đa Dạng Và Bảo
    HỘI NGHỊ KHOA HỌC TOÀN QUỐC VỀ SINH THÁI VÀ TÀI NGUYÊN SINH VẬT LẦN THỨ 6 ỐC NƢỚC NGỌT Ở VIỆT NAM: ĐA DẠNG VÀ BẢO TỒN ĐỖ VĂN TỨ Viện Sinh thái và Tài nguyên sinh vật, Viện Hàn lâm Khoa học và Công nghệ Việt Nam Ốc nước ngọt có một vai trò quan trọng trong các hệ sinh thái thủy vực và đời sống hàng ngày của người dân Việt Nam. Nhiều nghiên cứu đã chỉ ra rằng ốc nước ngọt có tính đa dạng và mức độ đặc hữu cao. Tuy nhiên, các dẫn liệu đã có chưa phản ánh hết mức độ đa dạng ốc nước ngọt ở nước ta, các thông tin về loài còn thiếu, nhiều vấn đề phân loại học còn chưa sáng tỏ và thiếu sự đánh giá về tình trạng bảo tồn của nhóm này. Trong vài thập kỷ qua, sự suy thoái và ô nhiễm môi trường sống đã đặt nhiều loài ốc nước ngọt của Việt Nam trong tình trạng bị đe dọa tuyệt chủng. Các nghiên cứu gần đây đã chỉ ra rằng trong các nhóm thủy sinh vật nước ngọt, nhóm thân mềm (trai, hến, ốc) là một trong những nhóm bị đe dọa nhiều nhất (Kay, 1995; Darwall và cộng sự, 2011). Theo Cuttelod và cộng sự (2011), mức độ đe dọa thân mềm nước ngọt ở vùng Indo-Burma (trong đó có Việt Nam) chỉ xếp sau châu Âu. Nghiên cứu ốc nước ngọt của Việt Nam bắt đầu tiến hành từ thế kỷ XIX khi Cross và Fisher (1863) công bố 45 loài thân mềm nước ngọt Nam Việt Nam.

Phylogenetic distributed in lakes, rivers, and streams in eastern Asia, relationships within the Chinese semisulcospirids including Far East Russia, Japan, Korean peninsula, and were assessed via DNA sequences from China, and in western North America (Köhler, 2016, 2017; Liu mitochondrial analysis (cytochrome c oxidase I and et al., 1993; Strong & Köhler, 2009; Yen, 1939). Basic 16S rRNA). This research contains most knowledge on freshwater gastropods in China was first morphospecies of semisulcospirids previously established in the late nineteenth and early twentieth recorded in China. Based on these results, the family of Chinese Semisulcospiridae is represented centuries (e. g., Dautzenberg & Fischer, 1906, 1908; Fulton, by three genera: i. e., viviparous Semisulcospira 1914; Heude, 1888), with all cerithioidean freshwater Böttger, 1886, oviparous Hua Chen, 1943 and gastropods designated under the single genus Melania Koreoleptoxis Burch and Jung, 1988.
