I'm not sure I get all the drift here, but I've been in the woods for a couple of weeks. I was not informed about a hatchery meeting, but I am involved with the Stakeholder's group for the Great Lakes Fishery Commission, so I've heard much of this. I have not posted a lot of the discussion as that was the request of the GLFC and OMNR and NYSDEC staffers, only when we have been ok'd to communicate something from a meeting (mainly long conference calls) have I posted it.
The legal agreement that Clint has referred to is the Fish Community Objectives for Lake Ontario, and there was significant public input to the document. It can be found on the Great Lakes Fishery Commission website.
http://www.glfc.org/. On the far right in the row of green tabs is one labelled Boards and Committees. Click on that, choose the Lake Ontario Committee and then scroll down to Fish Community Objectives 2013, the full document is there. As has been stated, both the United states and Canada have made a commitment to keep the King as the top level pelagic predator, and the Lake Trout as the benthic predator.
Another important document in this discussion is the Lake Ontario Lakewide Action and Management Plan (LAMP), which is summarized at
http://www.dec.ny.gov/lands/92335.html. I believe the emphasis on Native Species (Lake Trout and Atlantic Salmon) comes from that plan. But as Clint points out, if the goal of the managers was to eliminate the kings, the best course of action now would be to do nothing, as the numbers of kings put out there would crash the alewife, likely beyond recovery, at which point native species rehabilitation should be possible, although maybe not in my remaining lifetime.
