Here is a rather preliminary and now old 8 page document from 1998 done by the Department of Fisheries and Oceans examining the efficacy of catch and release measures for conservation of Atlantic salmon in eastern Canada. Some of the major conclusions are:

survival rates can be 100% in well handled fish

Temperatures above 20 C (68 F) are very stressful

MSW salmon likely have higher survival rates than grilse owing to the fact that they have more energy reserves

Higher mortality occurs in fish that have recently entered freshwater than those who have had time to adapt to the osmotic stress of going from salt to freshwater
