In this perspective, the numerical extrapolation applied to incomplete “S.A.D.” can effectively compensate for S.A.D.s incompleteness, when having to deal with substantially incomplete samplings. Indeed, almost as much information can be released from extrapolated “S.A.D.s” as would be obtained from truly complete “S.A.D.s”, although the taxonomic identities of unrecorded species remain of course ignored by numerical extrapolation. To take full advantage of this new approach, a recently developed procedure allowing the least- biased numerical extrapolation of “S.A.D.s” has been applied to three partially sampled gastropods communities associated to coral-reef in Mannar Gulf (S-E India). -
Growth of Florida Fighting Conch, Strombus Alatus, in Recirculating Systems
Contribution No. 666 Growth of Florida Fighting Conch, Strombus alatus, in Recirculating Systems 2 AMBER SHAWL', DAVE JENKINS , :tvlEGAN DAVIS I, and KEVAN MAIN2 I Harbor Branch Oceanographic Institution Aquaculture Division 5600 US 1 North Ft. Pierce, Florida 34946 USA [email protected],· mdavis@hboi. edu 2 Mote Marine Laboratory 1600 Ken Thompson Parkway Sarasota, Florida 34236 USA [email protected],· [email protected] ABSTRACT With the increased interest in water conservation and the need to reduce the discharge of effluent from aquaculture production systems, there has been a shift from open, flow-through systems to recirculating aquaculture production systems. In 2001, Harbor Branch Oceanographic Institution developed the first recirculating conch aquaculture program. Two important aspects of conch aquaculture are detennining the stocking density and water quality parameters in growout systems that yield the fastest growth rate and the highest survival. An experiment was conducted from March 11 - June 3, 2003 at two Florida sites, Harbor Branch Oceanographic Institution and Mote Marine Laboratory, to compare survival and growth of juvenile conch in a recirculating growout system. The recirculating system consisted of raceways troughs with an elevated sand substrate. The three replicate raceway troughs at each site were stocked with juvenile (16.9 ± 1.9 shell length) Florida fighting conch, Strom bus alatus at 75 conchlm2 (l09 and 140 conch per replicate at Harbor Branch and Mote, respectively). In 12 weeks, the conch grew 18.8 mm or 0.22 mmI day at Harbor Branch and 22.5 mm or 0.27 mmJday at Mote. There was a significantly faster growth rate at Mote, which appeared to be due to a lower stocking density throughout the experiment. -

COMMISSIONED REPORT Summary Seagrass (Zostera) beds in Orkney Commissioned Report No. 765 Project No: 848 Contractors: Emma Jackson (The Marine Biological Association of the United Kingdom) and Malcolm Thomson (Sula Diving) Year of publication: 2014 Keywords Seagrass; Zostera marina; Orkney; predictive model; survey. Background Seagrasses (Zostera spp) are marine flowering plants that develop on sands and muds in sheltered intertidal and shallow subtidal areas. Seagrass beds are important marine habitats but are vulnerable to a range of human induced pressures. Their vulnerability and importance to habitat creation and ecological functioning is recognised in their inclusion on the recommended Priority Marine Features list for Scotland’s seas. Prior to this study, there were few confirmed records of Zostera in Orkney waters. This study combined a predictive modelling approach with boat-based surveys to enhance under- standing of seagrass distribution in Orkney and inform conservation management. -

If urbanisation is accompanied by a concomitant increase in shipping then this may also be a factor, i.e. increased propagule pressure of non-native species due to translocation beyond their native range via the hulls of ships and/or in ballast water. Singapore is potentially highly vulnerable to invasion by non-native marine species as its coastline comprises over 60% seawall and it is one of the world’s busiest ports. The aim of this study is to investigate the native, non-native, and cryptogenic molluscs found on Singapore’s seawalls. -

Main aim of this compilation is to give interested non-professionals better access to and understanding of sea shells and squids. As often long-lived and relatively stationary species, molluscs can provide a key function as water quality indicators. The taxonomic classifi cation was based on the Mollusca databases CLEMAM and ERMS (MARBEF). The list includes 309 species. > Kurzfassung Eine Liste deutscher Namen der marinen und Brackwasser-Mollusken der deutschen Küstengewässer und der Ausschließlichen Wirtschaftszone (AWZ) der Nord- und Ostsee wurde erstellt.

Agglutinins with Binding Specificity for Mammalian Erythrocytes in the Whole Body Extract of Marine Gastropods
© 2019 JETIR June 2019, Volume 6, Issue 6 www.jetir.org (ISSN-2349-5162) AGGLUTININS WITH BINDING SPECIFICITY FOR MAMMALIAN ERYTHROCYTES IN THE WHOLE BODY EXTRACT OF MARINE GASTROPODS Thana Lakshmi, K. (Department of Zoology, Holy Cross College (Autonomous), Nagercoil – 629 004). Abstract Presence of agglutinins in the whole body extract of some locally available species of marine gastropods was studied by adopting haemagglutination assay using 10 different mammalian erythrocytes. Of the animals surveyed, 14 species showed the presence of agglutinins for one or more type of erythrocytes. The agglutinating activity varied with the species as well as with the type of erythrocytes. Rabbit and rat erythrocytes were agglutinated by all the species studied. Highest activity of the agglutinins was recorded in the extract of Fasciolaria tulipa and Fusinus nicobaricus for rabbit erythrocytes, as revealed by a HA (Haemagglutination) titre of 1024, the maximum value obtained in the study. Trochus radiatus, Tonna cepa, Bufornia echineta, Volegalea cochlidium, Chicoreus ramosus, Chicoreus brunneus, Babylonia spirata, Babylonia zeylanica and Turbinella pyrum are among the other species, possessing strong (HA titre ranging from 128 to 512) anti-rabbit agglutinins. Agglutinins with binding specificity for rat erythrocytes have been observed in the extract of Trochus radiatus, Fasciolaria tulipa and Fusinus nicobaricus. None of the species agglutinated dog, cow, goat and buffalo erythrocytes. Agglutinins with weak activity against human erythrocytes were observed in Chicoreus brunneus (HA = 4 – 8). The present work has helped to identify potential sources of agglutinins among marine gastropods available in and around Kanyakumari District and thereby provides the baseline information, in the search for new pharmacologically valuable compounds derived from marine organisms. -
