Very interesting thread. Bruce or Bz, have either of you told PLM about PB and this thread in particular? It might be a good opportunity for them to address your questions and perhaps pick up some clients.

I agree witjh the comments of "bz" who said: I think it is very possible that they've qoted the wrong species. The ponds I've seen on the PLM property are just shallow sloughs so I can't believe they stay very cold. I don't "know" if that's where they actually raise them but I don't know of any trout waters anywhere near where they are located. And if they are selling them to attract ducks they are selling them for stocking into shallow sloughs. Doesn't add up.
Something is wrong in this picture so far. One possibility is the scuds are G.lacustris and they have a strain that is adapted to warmer water or they assumed the species that were thriving for them were G.lacustris. They may be growing the species that is more tolerant of warmer water - Gammarus fasciatus. Another possibility is the shallow water where they raise their scuds have seepages from underground springs that provide cool water refugia in summer.

I wish someone would have told me this post was going one. Over 4 years later I see it.  Good read however and funny at times.  We don't raise the shrimp on our property or even by our town...we harvest out of native clean ponds in central MN. Most of these ponds DO have fish in them and therefore are also deeper ponds so not to winter-kill. I have never measured the water temp during the summer but I would guess it gets to 70F for sure or even up to 80F at times...just our normal lake temps during the summer around here. Vegetation consists of Ceratophyllum, Myriophyllum, Potamogeton, Utricularia, etc...just our usual normal pond weeds we have. Most of what we harvest is G. lacustris...but we can get some H. azteca in there since they are very common in our ponds as well. Let me know if any questions and shoot me an email to let me know if there is a post I should respond [email protected]Kyle
