I am talking about all fishermen, not just hook and liners.

Sam Wright proposed an intereting question/position one time. He pointed out that one could view any additive mortality to salmonids as being harvest. This is harvest by hook and line (adult or juvenile), net, increased sediment due to logging roads, increased temperatures due to canopy removal, increased mortality due to dams, losses due to hatchery operations, and a myriad of other losses.

His point, and this applied to the 50:50 sharing but could be applied to any discussion of mortality, is that society (or some segments) has chosen (for example)to harvest salmonids as eggs (sediment) rather than as returning adults.

As such, the question of mortality is really about who gets it and why.
