Cytological studies in Salmo trutta and Salmo alpinus [PDF]
Ten populations of Salmo trutta and six populations of Salmo alpinus have been studied cytologically. Both species have the chromosome number 2n = 80. In Salmo trutta the number of metacentric chromosomes varies between 15 and 24 with an average mean of 20, which gives a nombre fondamental (N. F.) of 100.

Effect of polyploidization on survival of sea, brook, and rainbow trout hybrids during incubation and early feeding period [PDF]
Effect of polyploidization on survival of brook trout (Salvelinus fontinalis), sea trout (Salmo trutta morpha trutta) and rainbow trout (Salmo gairdneri) hybrids, including reciprocal crosses, during incubation and larval stages period was tested.

A hierarchical model to estimate the abundance and biomass of salmonids by using removal sampling and biometric data from multiple locations [PDF]
We present a Bayesian hierarchical model to estimate the abundance and the biomass of brown trout (Salmo trutta fario) by using removal sampling and biometric data collected at several stream sections.

Field and laboratory approaches to assess "estrogen disruption" in the brown trout "Salmo trutta" [PDF]
In recent years, the annual catches of brown trout and other native fish species have been declining in Switzerland about 60%. One hypothesis was that the reduced catch is linked to estrogen-active chemicals entering the aquatic environment via waste ...

Do native brown trout and non-native brook trout interact reproductively? [PDF]
Reproductive interactions between native and non-native species of fish have received little attention compared to other types of interactions such as predation or competition for food and habitat.

The course of migrations of smolts of the brown trout (Salmo trutta m. trutta L.) grown in the rivers of Pomerania [PDF]
In the present report the daily seaward migrations of the brown trout (Salmo trutta m. trutta L.) smolts, grown in natural conditions in Pomeranian rivers: the Mołstowa, surveyed for one season, the Gowienica-for twe seasons, and the Osówka-for two ...
