Sure.
This is a fishery that would happen at or near where the fish are arriving at their spawning grounds. One of the advantages of that is that typically you will have separated out different stocks, which may be at varying levels of abundance. At a terminal location, you may have a hatchery component of the return that are marked, and you may have a wild component of the return that are going to their natal streams in that same area. By virtue of increasing mass marking, there may be the scope for more fishing opportunity on those marked fish because we have the confidence that they won't have any undesirable impact on the wild stocks that may also be in that same area.
