Movement patterns and spawning activity of individual nase

Introduction In European rivers, cyprinids play a major role in riverine ecosystems because of their high abundance (Philippart, 1981; Mann and Penczak, 1986). Their variety of life-history patterns and habitat requirements make cyprinids good indicators of the ecological quality and the structural proper-ties of river systems (Keckeis et al

Activity and food choice of piscivorous perch Perca

Introduction Perch is a common fish species in European lakes (Thorpe, 1977), occurring, for example, in >95% of all Danish lakes, where it often accounts for a substantial part of the fish number and biomass (Jensen et al., 1997). The diel and seasonal activity of perch (Perca fluviatilis L.) has been the subject of several studies. In

Cultivation of bigheaded carps and other Chinese carps, for example, grass carp and black carp, has a long history that can be dated back to the Tang dynasty (618 907 AD) (Li et al., 1990).

Genetic diversity of the pan-European freshwater mussel

INTRODUCTION Unionoid mussels are among the most critically endangered fauna and are globally in decline (Strayer, 2008). Conserving unionoid populations has wider importance because these animals are responsible for important ecosystem functions and services (e.g. food resource to higher trophic levels, clearing the water, control of the

Identification of non-native freshwater fishes in Europe

Welcomme (1992) found that transfers of European cyprinids, poeciliids, centrarchids and salmonids, took place at a relatively early stage, and have since been succeeded by those of cichlids and Asian cyprinids. Introductions of aliens species peaked towards the end of the 19th century and again, after a lull, in the 1960s and 1970s.

INTRODUCTION Background. Cyprinid fishes constitute the greatest number of all freshwater teleost fish species and despite their great diversity in Asia, Europe, Africa and North America, there are no native cyprinids in Australia, New Zealand or New Guinea. Cyprinids were introduced to Australia 150 years ago probably as a result of

Local adaptation in growth and survival of P. phoxinus to a spe-cific pathogen, the trematode Diplostomum phoxini, has been highlighted in the early 1990′s (Ballabeni and Ward 1993; Ballabeni 1994).

Cyprinids are the most speciose fish family in European freshwaters (Reyjol etal., 2007) and include many endangered endemic species (Smith & Darwall, 2006), so information on these effects is critical for their conservation.
