2006 Inventory of Research Relating to
Salmon Mortality in the Sea

Listing of on-going research projects relating to salmon mortality in the sea by SALSEA Workpackage

SALSEA Work Packages

Work package 1 : Supporting technologies


Task 1: Genetic tagging to determine stock origin

Work package 2: Early migration through the inshore zone: fresh water, eatuaries and coastal waters

Task 1: Investigate the influence of biological characteristics of Atlantic salmon smolts on their marine mortality

Task 2: The impacts of physical factors in fresh water on marine mortality of Atlantic salmon

Task 3: Preparing to migrate – investigate the influence of freshwater contaminants on the marine survival of Atlantic salmon

Task 4: The part played by key predators

Task 5: The impact of aquaculture on mortality of salmon
