This work aims to present an historical review of the ecosystem services provided by
anadromous fish (ie, species that migrate from the sea to the river to spawn) throughout …

Ecological models for stream fish range in scale from individual fish to entire populations.
They have been used to assess habitat quality and to predict the demographic and genetic …

Stocking represents the most important management tool worldwide to increase and sustain
commercial and recreational fisheries in a context of overexploitation. Genetic impacts of this …

Habitats modify the population ecology of species. Here, we show how low water level
influences abundance and size of adult anadromous brown trout (Salmo trutta) entering a …

Aim The study of the factors that influence population connectivity and spatial distribution of
genetic variation is crucial for understanding speciation and for predicting the effects of …

Several countries have implemented stocking programmes to enhance abundance and fish
production by releases of hatchery-reared fish. However, due to fluctuations in population …

Early juvenile growth is a good indicator of growth later in life in many species because
larger than average juveniles tend to have a competitive advantage. However, for migratory …

Linking temporal variations of genetic diversity, including allelic richness and heterozygosity,
and spatio‐temporal fluctuations in population abundance has emerged as an important tool …

The fragmentation and destruction of natural habitats by human intervention is producing a
continuous and inexorable reduction of the size of populations in multitude of species all …

De aspecto fusiforme, muy ligeramente comprimido lateralmente y dotado de un pedúnculo
caudal ancho y fuerte. Un carácter común a toda la familia Salmonidae es la presencia de …
