  • Early Stages of Fishes in the Western North Atlantic Ocean Volume
    ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation.

  • An Annotated Bibliography of Diet Studies of Fish of the Southeast United States and Gray’S Reef National Marine Sanctuary
    Marine Sanctuaries Conservation Series MSD-05-2 An annotated bibliography of diet studies of fish of the southeast United States and Gray’s Reef National Marine Sanctuary U.S. Department of Commerce February 2005 National Oceanic and Atmospheric Administration National Ocean Service Office of Ocean and Coastal Resource Management Marine Sanctuaries Division About the Marine Sanctuaries Conservation Series The National Oceanic and Atmospheric Administration’s Marine Sanctuary Division (MSD) administers the National Marine Sanctuary Program. Its mission is to identify, designate, protect and manage the ecological, recreational, research, educational, historical, and aesthetic resources and qualities of nationally significant coastal and marine areas. The existing marine sanctuaries differ widely in their natural and historical resources and include nearshore and open ocean areas ranging in size from less than one to over 5,000 square miles. Protected habitats include rocky coasts, kelp forests, coral reefs, sea grass beds, estuarine habitats, hard and soft bottom habitats, segments of whale migration routes, and shipwrecks. Because of considerable differences in settings, resources, and threats, each marine sanctuary has a tailored management plan. Conservation, education, research, monitoring and enforcement programs vary accordingly. The integration of these programs is fundamental to marine protected area management. The Marine Sanctuaries Conservation Series reflects and supports this integration by providing a forum for publication and discussion of the complex issues currently facing the National Marine Sanctuary Program. Topics of published reports vary substantially and may include descriptions of educational programs, discussions on resource management issues, and results of scientific research and monitoring projects. The series facilitates integration of natural sciences, socioeconomic and cultural sciences, education, and policy development to accomplish the diverse needs of NOAA’s resource protection mandate.

  • The Secret Sex Lives of Sage-Grouse: Multiple Paternity and Intraspecific Nest Parasitism Revealed Through Genetic Analysis
    Behavioral Ecology doi:10.1093/beheco/ars132 Advance Access publication 21 September 2012 Original Article The secret sex lives of sage-grouse: multiple paternity and intraspecific nest parasitism revealed through genetic analysis Krista L. Birda, Cameron L. Aldridgea,b, Jennifer E. Carpentera, Cynthia A. Paszkowskia, Mark S. Boycea and David W. Coltmana aDepartment of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada T6G 2E9 Downloaded from bDepartment of Ecosystem Sciences and NREL, Colorado State University, in cooperation with US Geological Survey, 2150 Centre Avenue, Building C, Fort Collins, CO 80526, USA In lek-based mating systems only a few males are expected to obtain the majority of matings in a single breeding season and http://beheco.oxfordjournals.org/ multiple mating is believed to be rare. We used 13 microsatellites to genotype greater sage-grouse (Centrocercus urophasianus) samples from 604 adults and 1206 offspring from 191 clutches (1999–2006) from Alberta, Canada, to determine paternity and polygamy (males and females mating with multiple individuals). We found that most clutches had a single father and mother, but there was evidence of multiple paternity and intraspecific nest parasitism. Annually, most males fathered only one brood, very few males fathered multiple broods, and the proportion of all sampled males in the population fathering offspring aver- aged 45.9%, suggesting that more males breed in Alberta than previously reported for the species. Twenty-six eggs (2.2%) could be traced to intraspecific nest parasitism and 15 of 191 clutches (7.9%) had multiple fathers. These new insights have important implications on what we know about sexual selection and the mating structure of lekking species.

  • Note on Feeding Relationships of Three Species of Cyprinid Fish Larvae in Al-Huwaiza Marsh, Southern Iraq
    Mesopot. J. Mar. Sci., 2011, 26 (1): 35 - 46 Note on feeding relationships of three species of cyprinid fish larvae in Al-Huwaiza marsh, Southern Iraq S.M. Ahmed Agriculture College, University of Basrah, Basrah - Iraq [email protected] (Received: 28 November 2010 - Accepted: 8 February 2011) Abstract - Food composition of three cyprinid larvae (Cyprinus carpio, Carassius auratus and Alburnus mosulensis) in Al- Huwaiza marsh has been studied during March and April 2006. The diet of these cyprinid larvae were consist mainly of zooplankton dominated by copepods both adult and larval stages followed by Cladocera Rotifera, aquatic insects and Ostracoda. The food of plant origin also exists and consists of diatoms and filamentous algae. Costello graphical plot showed that these larvae are generalist feeders. This strategy result in lower competition and allow these three species to co-occur in relatively high density in this marsh area. The food similarity between C. carpio and C. auratus was 0.60, between C. carpio and A. mosulensis was 0.44, while it was 0.72 between C. auratus and A. mosulensis. The food overlap analysis showed that C. carpio; C.auratus and A.mosulensis larvae share a wide range of prey types. Competition for food is possible However, direct competition seemed to be avoided to some extent as a result of great food availability in Al-Huwaiza marsh which makes it as a suitable nursery and feeding site for many cyprinid fish. Introduction Diet analysis of fishes allows us to understand their feeding strategy, their intra-or interspecific potential interaction (competition and predation) and indirectly indicate community energy flow (Ramirez-Luna et al., 2008).

  • Seahorse Manual
    Seahorse Manual 2010 Seahorse Manual ___________________________ David Garcia SEA LIFE Hanover, Germany Neil Garrick-Maidment The Seahorse Trust, England Seahorses are a very challenging species in husbandry and captive breeding terms and over the years there have been many attempts to keep them using a variety of methods. It is Sealife and The Seahorse Trust’s long term intention to be completely self-sufficient in seahorses and this manual has been put together to be used, to make this long term aim a reality. The manual covers all subjects necessary to keep seahorses from basic husbandry to indepth captive breeding. It is to be used throughout the Sealife group and is to act as a guide to aquarist’s intent on good husbandry of seahorses. This manual covers all aspects from basic set, up, water parameters, transportation, husbandry, to food types and preparation for all stages of seahorse life, from fry to adult. By including contact points it will allow for feedback, so that experience gained can be included in further editions, thus improving seahorse husbandry.
