Changes occurring over time in commercially exploited fish assemblages in lowland dam reservoirs

Life history change in commercially exploited fish stocks: an analysis of trends across studies

Age and size at maturation have declined dramatically in many commercial fish stocks over the past few decades - changes that have been widely attributed to fishing pressure. We performed an analysis of such trends across multiple studies, to test for the consistency of life history changes under fishing, and for their association with the intensity of exploitation (fishing mortality rate). We ...

Spatial Effects of Reservoirs on Fish Assemblages in Great Plains Streams in Kansas, Usa

Reservoirs are important components of modern aquatic ecosystems that have negative impacts on native aquatic biota both upand downstream. We used a landscape-scale geographic information system (GIS) approach to quantify the spatial effects of 19 large reservoirs on upstream prairie fish assemblages at 219 sites in Kansas, USA. We hypothesized that fish assemblage structure would vary with inc...

Influence of a large dam on the longitudinal patterns of fish assemblages in Qingyi Stream.

Using seasonally collected data (2009-2010) from 15 sampling sites that represent first- to fifth-order streams within the Qingyi watershed, we examined the spatio-temporal patterns of fish assemblages along two longitudinal gradients to explore the effects of a large dam on fish assemblages at the watershed scale. No significant variation was observed in either species richness or assemblage s...
