In the 1980s, a database of the species of fish and cyclostomes in Switzerland was compiled. This has now been updated. The data which cover species in 20 families, were collected by sampling at 5904 watercourses and 752 stillwater sites (lakes, ponds, etc), and are presented in this publication. For each species there are sections on world-wide distribution, biology, habitat and distribution in Switzerland, and species characteristics. There are also distribution maps for each species, and tabulated data on the sampled sites. At the end of the book there is a key to identification of the species. 233 pp., num. distribution maps and figs, hc gr. 8 [bilingual German / French]. …

Ca troisi?me ?dition r?actualis?e de l Atlas de distribution des poissons et cyclostomes de Suisse met en ?vidence les r?cents et importants bouleversements observ?s de la faune piscicole pr?sente dans les eaux helv?tiques. Les activit?s humaines de loisirs, de transport et de commerce ont provoqu? des modifications des aires naturelles de distribution des esp?ces indig?nes et favoris? la prolif?ration d esp?ces non indig?nes et arfois envahissantes. Gr?ce aux nouvelles g?n?tiques, il a ?galement ?t? possible de mettre en ?vidence ou de confirmer l existance de nouvelles esp?ces, souvent m?connues ou confondues. Cet ouvrage de la s?rie Fauna Helvetica synth?tise les connaissances scientifiques actuelles en constante ?volution ainsi que la distribution de la faune piscicole suisse. Il se base sur les donn?es les plus r?centes ainsi que sur la banque de donn?es de distribution des poissons et cyclostomes de Suisse, g?r?e par le Centre suisse de cartographie de la faune (Info fauna - CSCF). La base de donn?es contient ? ce jour 69 817 rescensements valid?s de poissons et cyclostomes, dont 61 020 issues d inventaires sur des eaux courantes et 8 797 sur des plans d eau.Ces donn?es proviennent principalement d ?chantillonages effectu?s dans le cadre de travaux de gestion halieutique, de recherche scientifique ou d expertises pratiqu?es et d expertises pratiqu?es par des organismes priv?s ou publics dans le cadre d intervention technique touchant aux eaux. A ces donn?es se sont ajout?es ?galement de nombreuses informations mus?ales. Pour chaque taxon, des informations g?n?rales sur sa distribution.Le statut de menace en Suisse est tir? de la r?actualisation de la Liste rouge des poissons et cyclostomes de Suisse effectu?e en 2018,dont la publication de l OFEV est pr?vue en 2019. Un guide d identification sous forme de cahier compl?mentaire est ?galement disponible. Ce guide peut ?tre emport? sur le terrain afin d identifier la plupart des poissons et cyclostomes de Suisse. Ses illustrations permettent au d?butant comme au naturaliste exp?riment? de reconna?tre les poissons sur la base de crit?res simplifi?s de manipre non invasive pour l animal. This third updated edition of the Swiss Fish and Cyclostome Distribution Atlas highlights recent and significant changes concerning the fish fauna of Swiss waters. Human recreation, transportation and trade activities have led to changes in the natural range of distribution of native species and the proliferation of non-native and sometimes invasive species. Thanks to the new genetic, it has also been possible to highlight or confirm the existence of new species, often unknown or confused. This book of the Fauna Helvetica series synthesizes the current scientific knowledge in constant evolution as well as the distribution of the Swiss fish fauna. It is based on the most recent data as well as on the distribution database of fish and cyclostomes in Switzerland, managed by the Swiss Wildlife Mapping Center (Info fauna - CSCF). The database currently contains 69,817 verified validations of fish and cyclostomes, of which 61,020 come from inventories of streams and rivers and 8,797 from lakes and other stagnant waterbodies. For each taxon, general information on its distribution is given. The Red List status in Switzerland is based on an update of the Swiss Red List of Fish and Cyclostomes, the publication of which is scheduled for 2019. An identification guide in the form of a supplemental booklet is also available. This guide can be taken to the field to identify most of the fish and cyclostomes in Switzerland. The illustrations allow the beginner as well as the experienced naturalist to recognize fishes based on simplified criteria of non-invasive handling for the animal. 239 pp., num. distribution maps, hardcover gr. 8 / 48 pp., num. color figs, br. gr. 8, 2 Vols.
