Available in PDF, EPUB and Kindle. Book excerpt: Depuis quelques décennies le déclin des stocks de poissons sauvages en Méditerranée a entraîné un développement accru de l’aquaculture. En Corse, l’aquaculture est devenue aujourd’hui l’une des principales activités agricoles de l’île. En général, et chez les poissons en particulier, l'effet pathogène des parasites dans les conditions naturelles est réduit, conséquence de l'équilibre établi au cours de l'évolution dans le système hôte-parasite. En aquaculture c'est l'accumulation, chez un individu hôte, d'un organisme étranger (virus, bactérie, ou parasite) qui entraîne un effet pathogène dont la gravité est proportionnelle à cette accumulation (Combes, 1990). Les animaux élevés en mer ouverte sont exposés à un grand nombre d’agents parasitaires à cycle direct et indirect (Paperna, 1998). Cette étude parasitaire nous a permis d’identifier et de recenser les communautés parasitaires présentes sur les poissons d’élevage de Corse. Sept espèces de parasites ont été identifiées sur le bar commun et la daurade royale Sparus aurata. Ces sept espèces représentent quatre groupes de parasites : - Les Monogènes qui parasitent le plus fréquemment nos espèces de poissons avec Diplectanum aequans sur le bar commun, Sparicotyle chrysophrii et Furnestinia echeneis sur la daurade royale ; - Les Copépodes parasitant uniquement le bar commun avec les espèces Lernanthropus kroyeri et Caligus minimus ; - Les Isopodes avec l’espèce Cerotothoa oestroides rencontrée chez le bar commun ; - Les Myxosporidies avec l’espèce Ceratomyxa labracis, parasites occasionnels du bar commun. Nous avons ainsi pu mettre en évidence l’importance de l’influence des facteurs environnementaux et des paramètres physiologiques de l’hôte dans la répartition parasitaire. Des méthodes statistiques nous ont également permis de définir les interactions potentielles entre les espèces parasites et les espèces-hôtes, mais également entre les écosystèmes hôtes. Ce travail réalisé en collaboration avec les professionnels de la filière aquacole, pourra se révéler comme un outil de gestion et de prévention afin d’éviter toute perte due aux pathogènes et ainsi d’écarter tout risque pouvant entraîner des conséquences économiques désastreuses pour les exploitants.
Download or read book Fish Parasites written by Woo and published by CABI. This book was released on 2011 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on pathobiology and protective strategies against protozoan and metazoan parasites of fish, this book reviews the latest research on important parasites: those that cause financial hardships to the aquaculture industry, have been introduced to new geographical regions through transportation of infected fish, are pathogenic to groups of finfish and detrimental to production, are highly adaptable and not host-specific with worldwide distributions, and that may serve as disease models for studies on other pathogens. It also highlights gaps in the knowledge to help direct future research.
Download or read book Fish Parasites A Handbook of Protocols for their Isolation Culture and Transmission written by Ariadna Sitja-Bobadilla and published by 5m Books Ltd. This book was released on 2021-06-30 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Good fish health and welfare are essential components of sustainable aquaculture and in this regard, fish parasites constitute a major constraint to production. The aquaculture industries of areas affected by various disease outbreaks have suffered considerably from the impacts of marine and freshwater parasites. It is therefore fundamentally important to take steps to prevent parasite infection, as well as to properly identify, monitor and treat outbreaks when they occur. ParaFishControl, an EU-funded project involving industry, academic and government partners drawn from across Europe, whose work has led to this book, is dedicated to effectively understanding and controlling a diverse range of fish parasites in order to promote the sustainability and competitiveness of the European aquaculture industry. Fish Parasites contains detailed outlines of the most up to date protocols for parasite isolation, culture and transmission, as well as detailed procedures for reproducing parasitic infections in a laboratory environment. Protocols for tasks such as monitoring parasitic infection, isolating parasites and preparing parasite material are explained in detail. In addition, an introduction is provided to the biology and host interactions of each parasite discussed. Fish Parasites provides an essential guide for those who are currently researching fish-parasite relations, as well as for those who may study fish health and welfare more generally or otherwise have broader interests in fish parasites. 5m Books

Download or read book Biological Invasions in Europe and the Mediterranean Basin written by F. di Castri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the massive change in the area of distribution of many world biota across classical biogeographical realms, and of the drastic restructuring of the biotic components of numerous ecosystems, the Scientific Committee on Problems of the Environment (SCOPE) decided at its general Assembly in Ottawa, Canada, in 1982 to launch a project on the 'Ecology of Biological Invasions'. Several regional meetings were subsequently organized within the framework of SCOPE, in order to single out the peculiarities of the invasions that took place in each region, the behaviour of their invasive species and the invasibility of their ecosystems. Most noteworthy among such workshops were one in Australia in August 1984, one concerning North America and Hawaii in October 1984, and one dealing with southern Africa in November 1985. A leitmotiv of these workshops was that most of the invasive species to those regions were emanating from Europe and the Mediterranean Basin, inadvertently or intentionally introduced by man. It was therefore considered as a timely endeavour to organize the next regional meeting in relation to this region. The workshop on 'Biological Invasions in Europe and the Mediterranean Basin' was held in Montpellier, France, 21 to 23 May 1986, thanks to the financial support of SCOPE and of the A.W. Mellon Foundation, and the logistic facilities of the Centre National de la Recherche Scientifique (C.N .R.S.).

Download or read book Heron Conservation written by James Anthony Kushlan and published by Helm. This book was released on 2000 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heron Conservation provides a comprehensive update following two distinct threads. The status and conservation needs of herons are first presented on a regional basis, in a series of chapters set at continental or subcontinental scale. Over 200 biologists and heron conservationists - many associated with the Heron Specialist Group sponsored by Wetlands International and IUCN - have contributed to the data summarised here and these very latest census and survey results provide the most up to date and detailed picture of heron populations currently available. Chapters discussing several critical issues in heron conservation follow, often focusing on the international nature of the problem. Many heron populations are migratory and depend upon conservation of both summer and wintering wetland habitats often located on different continents. Effective conservation of these wetlands of international importance depends in large part on local and regional socio-economic factors. Herons, to the extent that they require maintenance of wetland functioning, should be an integral part of sustainable wetland conservation. Features: * Fascinating insight into a topical issue * Beautiful colour pho
