Carcass - Not sure I understand your question......
As I understand it, the study that WDFW is doing will look at the survival rates of fish that are caught in gill nets, and subsequently released. (Ditto for recreationally caught fish.) I realize the Tribes don't intentionally release anything caught from their gill nets, but they recognize there is unaccounted losses from fish that drop out, or get thru the nets. But nobody has done a study to determine the survival rate of these fish. Presumably, the study on Gray's Harbor will provide some indication of the C&R survival of fish that encounter gillnets.
I realize it's the C&R survival rate from recreationally caught fish that the Tribes are most interested in.
