Predicting the ecological consequences of river management for a riverine cyprinid fish.
… and habitat models fail to incorporate fish behaviour and the interactions between fish and their environment, thus limiting their ability to predict management-relevant, population responses to environmental change. In order to address these weaknesses, an individual-based model is …

Otolith morphologies in the genus sinocyclocheilus
Sinocyclocheilus is a genus of Cyprinid fish found in southern China. This genus contains 68 species of which 40 species have adaptations for life in cave habitats. A common adaptation seen in fish that live in caves with no light is the loss of vision. Such cavefish must therefore rely on other …

Applications of fish scale analysis to understand growth dynamics of fish populations
… to derive ecological information about fish populations is a fundamental tool in fisheries assessment, specifically the back-calculation of fish lengths. This study highlights the potential errors associated with correction factors (c) because of poor sampling and provides a validation …

Invasion and evolutionary history of a generalist fish parasite.
… significant risk to native biodiversity. The cyprinid fish species, Pseudorasbora parva, is a well-studied example of accidental introduction to a new range; it has been accidentally introduced from China to Europe. Pseudorasbora parva has been hypothesized to have also introduced the …

Life history of the endangered fine-rayed pigtoe pearly mussel, Fusconaia cuneolus (Lea, 1840), in the Clinch River, Virginia
… of gravidity and glochidial release, required fish hosts, and age and growth characteristics of Fusconaia cuneolus were studied in the upper Clinch River, Virginia during 1986 and 1987. This summer brooder is gravid from mid-May through late July, releasing most glochidia in midJune. Gills of …

Ecology and conservation of Garra ghorensis, an endangered freshwater fish in Jordan
… focal species of the research was the freshwater cyprinid fish Garra ghorensis. Endemic to the southern Dead Sea basin of the Middle East, it is ‘Red listed’ by the IUCN as ‘endangered’. It inhabits the small rivers of the basin (‘wadis’), existing within fish communities of very low species …

Factors affecting the dispersal of coarse fish
Globally, freshwater fisheries are faced with numerous impacts that compromise fish populations. A knowledge and understanding of riverine fish movements are crucial for effective management and conservation of populations. However, there is a paucity of information about the spatial behaviour and …

Applying edge-core theory of intraspecific life-history variation to the control of invasive silver carp (hypophthalmichthys molitrix)
… (Hypophthalmichthys molitrix) are an invasive cyprinid fish that were introduced to North America in the 1970s and have since spread throughout the Mississippi River Basin. During the 2000s, silver carp invaded the Illinois River and began advancing towards the Laurentian Great Lakes, making …

The ecology of larval and juvenile fishes in lowland rivers, with particular emphasis on foraging
FEEDING ECOLOGY OF 0+ FISHESThere are numerous biotic and abiotic factors that affect the abundance of cyprinid fish stocks in rivers, many of which are poorly understood. The role of food availability during critical life stages is one of these factors that may determine the growth and survival of …
