Résumé :
|
The work providing the basis for this dissertation was carried out in the period 1996-1998. The studies involved in this Ph.D. project were designed to provide results that would answer some of unanswered questions, of which the most central are : - Is predation the main cause of smolt-loss in danish reservoirs ? (Paper I) - Are the smolt mortality rates in these reservoirs linked to the migratory behaviour of the smolts? (Paper I & VI) - Are certain "high risks areas" for smolts in the reservoirs ? (Paper I & VI)
