In GH & Willapa the modeled mortality rate includes drop outs and if I recall the tribal % is 4% in the model and Recs are 16% ( ? ) been awhile not being on the model bit. Bottom line is mortalities are modeled in and the drop out is part of it. Now the QIN net actual is running somewhere between 20 and 25% not 4% and frankly you can set on the bank and count how many the sea lions get. The NT Nets with the recovery box bit is a absolute joke as having broodstocked Chinook for many years and damn near did back flips to keep the adults alive. From my experience it is between 50 and 100 % on NT nets releases. Hell the QIN claim 100% on NT releases.

Bottom line for me is the simple fact that mortality on releases be it net or pole are nothing less than a fabricated best guess.
