[cool][#0000ff]W&B pretty much answered your question on the northerns. Already enough (too many) here and plenty of brood stock if DWR wants to "enhance" other waters.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Northerns are not a consideration for the waters that now hold tiger muskies. The tigers are a true sterile hybrid and there is absolutely no risk of a breakaway population due to spawning. That is not true of northerns. Put a boy and girl northern in a lake and within a couple of generations they can take over. There have been experiments with producing "triploid" (sterile) northerns, like they do with some trout species, but the results have never been 100% effective and DWR does not want to risk experimenting on Utah waters.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]I also agree with W&B that there will be plenty of energy put into this situation and it will not really be that long before Utah again has a source of tiger muskies...either home grown or next door neighbor tradeoffs. We already have reciprocal arrangement with neighbor states to exchange surplus eggs or fry for several species.[/#0000ff]
