Mark, there's a LOT of variables involved in this.
The data you have on tagged fish, especially recatch, if you have date, length and weight from each time you have that fish, some questions can be answered about growth rate but I can also provide info that indicates tagged fish, LMB and BCP in particular, showed a slower growth rate after tagging because of what KDWP believes to be a continued stress factor of the tag itself.
Maybe Lusk or some of the others a bit more in tune to the F1 can elaborate on some of this, but I think there are many, many items that need to be confirmed before assumptions are made.
