Wydoski, R. S. 1977 Relation of hooking mortality and sublethal hooking stress to qualy fishery management In RA Barnhart and TD Roelofs (ed.) Catch and Releas fishing as a management too. Humboldt State University.

Again these are the statsitcs I have found in Report by Hooton from BC in April 2001. I don't know about the individual experiments so I will let the numbers stand for themselves.
