Which study was this? The one I saw was 28% for J hooks and 4% for circles. The study actually indicated fishing bait was probably a better choise for c'n'r based on circle hooks. This was based just on hook damage and not the length of the fight which for most people I see fighting fish it is bound to be up over 30%. Anglers like Dave are probably in the minority when it comes to really fighting fish properly.
I know albie mortlity is really high as well. Higher than BFT. Would also like to see them kept in the water at all times if one is planning to release them.
