Estimates of survival of stream-dwelling brown trout using mark-recaptures

Estimated monthly apparent survival of stream-dwelling brown trout Salmo trutta in south-east Norway was higher in winter than in summer, and lower in Alpine bullhead Cottus poecilopus sites than in allopatric sites. Apparent survival denotes true survival x local site fidelity. Emigration may also...

More Information
Summary:Estimated monthly apparent survival of stream-dwelling brown trout Salmo trutta in south-east Norway was higher in winter than in summer, and lower in Alpine bullhead Cottus poecilopus sites than in allopatric sites. Apparent survival denotes true survival x local site fidelity. Emigration may also explain differences in apparent survival. All brown trout included in this study were at least 1 year old.
