The illustrated keys allow the rapid identification of species; in the introductory chapter is a key to the families of fish, which enable readers to quickly find the family to which their specimen belongs, and at the start of the chapter on each family, a detailed key identifies the exact species.

Covering the whole of Europe - from the lakes and rivers of Ireland in the west to the Danube basin in the east - this guide includes every species of fish found in both fresh and salt water, and provides distribution maps for each species.

Standard reference to the freshwater fishes of Europe covering 546 native and 33 introduced species. Includes diagnoses for all species with keys to genera and species, methods for identification, notes on habitat, biology, ecology, native, extirpated and introduced distributions, species conservation status (validated through IUCN procedures), uptodate taxonomy and nomenclature using modern methods and concepts. Included is a bibliography of more than 870 references.

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.
