Salmon farms destroying wild salmon populations in Canada, Europe: study ALISON AULD . Canadian Press NewsWire . Toronto: Feb 11, 2008. Abstract (Summary) The authors, including the late Halifax biologist Ransom Myers, claim the study is the first of its kind to take an international view of stock sizes in countries that have significant salmon aquaculture industries. The paper didn't look to the causes of the declines, which have been discussed in a series of studies over the last decade that have linked disease, interbreeding of escaped salmon and lice from farmed fish with reductions. Full Text (618 words) Copyright Canadian Press Feb 11, 2008 HALIFAX _ Salmon farming operations have reduced wild salmon populations by up to 70 per cent in several areas around the world and are threatening the future of the endangered stocks, according a new scientific study. The research by two Canadian marine biologists showed dramatic declines in the abundance of wild salmon populations whose migration takes them past salmon farms in Canada, Ireland and Scotland. ``Our estimates are that they reduced the survival of wild populations by more than half,'' Jennifer Ford, lead author of the study published Monday in the Public Library of Science journal, said in Halifax. ``Less than half of the juvenile salmon from those populations that would have survived to come back and reproduce actually come back because they're killed by some mechanism that has to do with salmon farming.'' The authors, including the late Halifax biologist Ransom Myers, claim the study is the first of its kind to take an international view of stock sizes in countries that have significant salmon aquaculture industries. -

S. et al. (2007): 20 years of the German Small-Scale Bottom Trawl Survey (GSBTS): A review. – Senckenbergiana maritima, 37 (1): 13 – 82, 50 Figs., 18 Tabs., 1 App., Frankfurt a. M.] The German Small-scale Bottom Trawl Survey (GSBTS) was initiated in 1987 in order to provide com- plementary investigations to the International Bottom Trawl Survey (IBTS) in the North Sea, using the same methodology but focussing high-intensity sampling on selected survey areas. Over the last 20 years, the initial number of 4 survey areas (10 ×eschweizerbartxxx 10 sng- nautical miles; “Boxes”) has been increased to 12, which are distributed over the entire North Sea. This paper describes the survey methods of the GSBTS, summarizes the scientific outcome of the first 20 years, and suggests that international fisheries research institutions would join the GSBTS. The major outcomes of the survey include to date: – Documentation changes in the distribution of fish species and in species assemblages (e.g. changes in species richness, shifts in the southern species component). – Geostatistical evaluation of GSBTS data. -
Larval Growth
LARVAL GROWTH Edited by ADRIAN M.WENNER University of California, Santa Barbara OFFPRINT A.A.BALKEMA/ROTTERDAM/BOSTON DARRYL L.FELDER* / JOEL W.MARTIN** / JOSEPH W.GOY* * Department of Biology, University of Louisiana, Lafayette, USA ** Department of Biological Science, Florida State University, Tallahassee, USA PATTERNS IN EARLY POSTLARVAL DEVELOPMENT OF DECAPODS ABSTRACT Early postlarval stages may differ from larval and adult phases of the life cycle in such characteristics as body size, morphology, molting frequency, growth rate, nutrient require ments, behavior, and habitat. Primarily by way of recent studies, information on these quaUties in early postlarvae has begun to accrue, information which has not been previously summarized. The change in form (metamorphosis) that occurs between larval and postlarval life is pronounced in some decapod groups but subtle in others. However, in almost all the Deca- poda, some ontogenetic changes in locomotion, feeding, and habitat coincide with meta morphosis and early postlarval growth. The postmetamorphic (first postlarval) stage, here in termed the decapodid, is often a particularly modified transitional stage; terms such as glaucothoe, puerulus, and megalopa have been applied to it. The postlarval stages that fol low the decapodid successively approach more closely the adult form. Morphogenesis of skeletal and other superficial features is particularly apparent at each molt, but histogenesis and organogenesis in early postlarvae is appreciable within intermolt periods. Except for the development of primary and secondary sexual organs, postmetamorphic change in internal anatomy is most pronounced in the first several postlarval instars, with the degree of anatomical reorganization and development decreasing in each of the later juvenile molts. -

By MARY J. RATHBUN, Assistant Curator, Division of Marine Invertebrates, U. S. National Museum. INTKODUCTION. Among the collections obtained by Dr. Robert E. Coker during his investigations of the fishery resources of Peru during 1906-1908 were a large number of Crustacea, representing 80 species. It was the original intention to publish the reports on the Crustacea under one cover, but as it has not been feasible to complete them at the same time, the accounts of the barnacles a and isopods b have been issued first. There remain the decapods, which comprise the bulk of the collection, the stomatopods, and two species of amphipods. One of these, inhabiting the sea-coast, has been determined by Mr. Alfred O. Walker; the other, from Lake Titicaca, by Miss Ada L. Weckel. See papers immediately following. Throughout this paper, the notes printed in smaller type were con tributed by Doctor Coker. One set of specimens has been returned to the Peruvian Government; the other has been given to the United States National Museum. Economic value.—The west coast of South America supports an unusual number of species of large crabs, which form an important article of food. -

E-mail: [email protected] 3Corresponding author Abstract During recent studies of phylogenetic relationships within Eriphioidea (sensu Ng et al. 2008), we recovered molecular evidence that the genus Platyxanthus A. Milne-Edwards, 1863, was not monophyletic. This prompted detailed morphological examination of the group, which confirmed that clear differences in characteristics of the carapace, first male pleopod, antennae, antennules, epistome, abdomen, and thoracic sternum serve to separate the species of Platyxanthus into three distinct groups. Comparison of the type material of Peloeus cokeri (Rathbun, 1930), (formerly Platyxanthus cokeri) to Peloeus armatus Eydoux & Souleyet, 1842, indicated that P. cokeri is a junior synonym of P. armatus and that Gordonoxanthus Števčić, 2011 (type species Platyxanthus cokeri Rathbun, 1930) is thus a junior synonym of Peloeus. Danielethus n. gen. is described to accommodate Platyxanthus patagonicus A. Milne-Edwards, 1863, and Platyxanthus crenulatus A. Milne-Edwards, 1863. -

Penchaszadeh1, 3 y Jorge P. Castello4 1 Conicet, 2 Universidad Nacional de Mar del Plata, 3 Museo Argentino de Ciencias Naturales, 4 Universidade Federal do Rio Grande, Brasil Resumen. Se reseña la creación del Instituto Interuniversitario de Biología Marina, Mar del Plata (IBM), Argentina, dependiente de la Universidad de Buenos Aires (UBA), la Uni- versidad Nacional de La Plata (UNLP), la Universidad Nacional del Sur (UNS) y del Poder Ejecutivo de la provincia de Buenos Aires. Se destaca su funcionamiento durante el período 1960-1976 hasta su desaparición en 1977 y las numerosas actividades desarrolladas en el pla- no de la biología marina argentina. También se mencionan los diversos cursos nacionales, congresos nacionales e internacionales realizados en dicha institución. Se destaca asimismo el rol del IBM con el Proyecto de Desarrollo Pesquero (FAO/PNUD) por haber sido asien- to de expertos internacionales y de los científicos argentinos que actuaron como contrapar- te dentro de ese proyecto. Como resultado de su accionar, el IBM editó 21 publicaciones científicas denominadasBoletines , productos de monografías originales, y 342 contribuciones científicas. Se señala el impacto de la intervención a las universidades con el golpe de Estado de 1966, de la persecución a los investigadores, los eventos durante el 1974-1976 y de la im- plantación de la dictadura militar en 1976 como factores desencadenantes de la emigración de sus investigadores y de la clausura del mismo instituto.
