No.
This will be the first attempt but what ewest listed above was one of the documents referenced in the beginning phases of planning for this. 3 other data sources are being used as reference as well and all tend to indicate the YPMxWAEF should have higher hatch success rates. Longevity of fry has been an obvious issue and the reason has not been determined yet either.
Quite a bit of thought has went into this and we've got some great folks at the Milford hatchery that live percid night and day.
