Available in PDF, EPUB and Kindle. Book excerpt: The need to gather available data on the Eurasien huchen - an important salmonid species - has been forced by a plain and, unfortunately, common fact of our times: the numbers and distribution of this biggest of salmonids have begun to decline and its range has begun to shrink. A seminar on the huchen - the European form of the species Hucha hucha - held in Zilina in February 1973 as a result of a suggestion of the Section for the Conservation of Fauna of the Slovak Zoological Society, indicated very clearly the sad situation. Data on the biology of the huchen are regrettably scarce despite several recent papers (Ivaska 1951, Svetina 1962, Prawochenski and Kolder 1968) with the aim of filling this gap. Supposing that without a thorough knowledge it is practically impossible to conserve any plant or animal species, the participants of the seminar concluded that the existing knowledge on the huchen should be compiled in an exhaustive monograph. The first such outline originated in 1977 under the authorship of J. Holcik, K. Hensel and L. Skacel, and was submitted as a research report to some of the central authorities. Even during the compilation of the report it became evident, however, that there is no difference between the huchen and its relative, the taimen. Consequently, we immediately began revising our first report, which took over three years.

Download or read book Conservation of Endangered Freshwater Fish in Europe written by Arthur Kirchhofer and published by Birkhäuser. This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.
Download or read book Ecological Sustainability of Fish Resources of Inland Waters of the Western Balkans written by Vladica Simić and published by Springer Nature. This book was released on 2023-12-31 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed evaluation of the hydro-ecological characteristics of the Western Balkans, an area characterized by still preserved inland waters and fish resources important for the European continent, as well as the biodiversity of inland waters important for the planet Earth. Freshwater ecosystems cover only 1% of the Earth's surface; however, they are a habitat for about 40% of fish species. At the same time, inland fisheries make less than 12% of the world's global fish catch, with 43% coming from low-income and food-deficient countries (Africa, South America, Southeast Asia). In Europe, the Western Balkans have significant fishing waters and fish resources, including the Middle Danube drainage (Sava, Drina, Velika Morava river systems), large ancient lakes (Skadar/Shkodra, Ohrid, Prespa, Dojran), and the Adriatic basin characterized by endemic and commercially important species. However, in contrast to the high fishing potential in a significant part of the Western Balkans, diverse and specific political, economic, and social factors largely had a negative impact on the state of fish resources. This volume is multidisciplinary and provides a sound knowledge base for scientific and practical fisheries. In addition, it may be a valuable guide for managers and conservationists worldwide to adapt methods and procedures for the ecological sustainability of fish resources under specific local, natural, and socio-economic conditions. Finally, the content is a good reference for natural sciences and agriculture students studying fish, fish resources, and fisheries sciences. It would improve their knowledge and perspectives on the challenges of sustainable use and conservation of inland water resources.
Download or read book Biologie des poissons d eau douce europ ens 2e d written by BRUSLÉ Jacques and published by Lavoisier. This book was released on 2013-07-01 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biologie des poissons d’eau douce européens, par son champ d’étude vaste et ambitieux, est un ouvrage de référence en ichtyologie dulçaquicole. Couvrant l’ensemble des aspects écologiques, écobiologiques, écophysiologiques et éthologiques, il dresse une présentation détaillée de 88 espèces auto- ou allochtones : morphologie, anatomie, distribution géographique, habitats, modes de vie et activités physiologiques. 453 autres espèces sont également répertoriées. Cette 2e édition a été largement revue et augmentée, compte tenu de l’importance des données scientifiques récentes. Outre des compléments utiles portant sur les habitats et les modes de vie, cet ouvrage s’enrichit des nombreux apports génétiques qui ont parfois « révolutionné » les concepts anciens relatifs aux origines paléo-historiques et paléo-géographiques des espèces. Des extensions ou des réductions de répartitions géographiques ont été consécutives à des transferts d’origine anthropique, à des dégradations physiques et chimiques et à la récente influence du Global Warming, sans oublier les changements de statut dans le domaine de la systématique. Au fil d’un livre d’une grande rigueur scientifique, abondamment illustré (dont 64 aquarelles originales et plus de 70 cartes géographiques pertinentes) et complété par un glossaire et une importante bibliographie, le lecteur abordera la connaissance des poissons européens d’une façon à la fois originale et attrayante. Cet ouvrage s’adresse à un large public : étudiants de 2e et 3e cycles en biologie, zoologie, écologie, hydrobiologie, environnement, ingénieurs et techniciens chargés de l’aménagement, de la gestion, de la qualité et de la protection des milieux aquatiques (services vétérinaires, de l’Environnement, de l’Agriculture, de l’Équipement…) auxquels il apportera les bases fondamentales nécessaires à leur action, et plus largement tous les passionnés d’ichtyofaune.
Download or read book Genetic Conservation of Salmonid Fishes written by Joseph G. Cloud and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the human population increases and nations become more industrialized, the habitat and water quality required for the survival of fish continues to decline. In addition to these environmental factors, fish populations are directly or potentially affected by harvesting, enhancement programs and introgression with hatchery-propagated or transgenic fish. To our knowledge no other scientific meeting has been assembled to consider the breadth of the problem, to review the technology that is presently available for the preservation of the germ plasm of salmonid stocks and to identify the scientific advances that are required to overcome the problems. Because many salmonids have spawning grounds within the confines of a specific region or county but will spend a large portion of their life cycle within the territorial waters of other countries or in the open ocean, the preservation of unique genes or gene pools in these animals requires international cooperation. This scientific meeting has provided a forum in which to discuss the problems, evaluate the present methods or technology for addressing the problems and suggest new directions or innovations that need to be implemented. During this meeting we limited our discussion to salmonid fishes. However, the general conclusions about the factors that affect the population dynamics of fish stocks and the technical aspects concerning the preservation of germ plasm will be applicable to other fish species.
Download or read book Women in ichthyology an anthology in honour of ET Ro and Genie written by E.K. Balon and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This special volume is dedicated to the contributions of women ichthyologists. Three colleagues were selected to represent all women ichthyologists, Ethelwynn Trewavas (ET), Rosemary Lowe-McConnell (Ro) and Eugenie Clark (Genie). All have had distinguished professional careers and have contributed in their own ways to their science. The career of each is highlighted by a personal interview with one of the editors of the volume, a bibliography of their lifetime publications, and a biography of their careers. Questions of historical inequities and current controversies in the treatment of women ichthyologists by their peers are raised and addressed by the women themselves. The personal and professional influences of these three women, and other women ichthyologists, are highlighted. A survey article by Pat Brown brings a number of women ichthyologists to the attention of a broader audience, and points the way for a more comprehensive historical consideration of the accomplishments and contributions of women ichthyologists. The volume continues with 16 solicited and contributed papers. ET's studies of taxonomy and life history are echoed in papers on the taxonomy and systematics of marine angelfishes, and of freshwater bitterlings, a review of reproduction in the North Atlantic ichthyofauna, and a comparison of reproductive styles and systematics of African minnows. Ro's studies on ecology, life history and behaviour are paralleled by papers on growth and metabolism in piranha, the community structure in tide pool fishes, and the social system and reproductive patterns in groupers. Genie's pioneering work on sexual roles and sex change, and her field studies of the behaviour of marine fishes are reflected in papers on gonadal structure and environmental sex determination in brook lamprey, sexual patterns in hawkfish, reproduction and systematics in phallostethids, gonadal structure and systematics in gobiids, reproductive and predator avoidance behaviour in razorfish, early ontogeny of an African mouth brooder, and alternative life histories in killifish.

Download or read book Principles of Salmonid Culture written by W. Pennell and published by Elsevier. This book was released on 1996-10-11 with total page 1071 pages. Available in PDF, EPUB and Kindle. Book excerpt: As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology. The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.

Download or read book Human Impact on Danube Watershed Biodiversity in the XXI Century written by Doru Bănăduc and published by Springer Nature. This book was released on 2020-04-20 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second-longest European river after the Volga, the Danube is one of the world’s most important rivers in terms of its geographical and historical significance. In recent history, it has served as a major international waterway and numerous cities, including four capitals, have been founded on its banks. The 2826km-long Danube has a watershed measuring 801,093 km2 that is now shared between 19 countries, from its source in the Black Forest to the Black Sea, into which it pumps an average of 827 km3 of water a year. This book describes and explains key landscape values interactions (geographical, cultural and natural heritage). It also identifies the threats and various types of human impact affecting this system in all the countries of the Danube River Basin, based on the investigations and perspectives of a team of experienced naturalists, and in the context of the early 21st century, in which the human-nature relationship is still far from balanced. These studies demonstrate how biodiversity, conservation and ecological studies can help us successfully promote mutual cooperation and combine our efforts to address problems as a responsible continent.
