Why do field bioligsts use the mark-release-recapture method when estimating the population size of small mammals? What are the principles of this method? ... Principals: 1. Capture some animals. 2. Mark them somehow. 3. Release them. 4. Later, recapture some of that species. 5. Using the ratio of marked to non...

We estimated the total size of the Atlantic salmon (Salmo salar) population complex (wild and cultured) in the Gulf of Bothnia, northern Baltic Sea, using a stratified mark-recapture method. In 2001 and 2002, 1970 salmon were captured by the commercial trapnet fishery and tagged with external arrow tags.
