From his pictures one cannot recognize the species. One needs to clearly and closely see the rostrum to distinguish between P.kadiakensis and P.paludosus. Since he says the the source pond gets ice cover, then I would trust the seller to have the correct specie name. Lower temperature survival limit of P. paludosus is 50F. A typical pond that gets ice cover will have near bottom water under ice temps of 39F.
For your complete satisfaction that you received the true P.kadiakensis put a couple(2-3) of them in a jar of pond water and slowly decrease the temperature to 40F. Put the jar in the refrigerator. If the shirmp survive for a few days in the 40F water they are P.kadiakensis.
Then if those stocked do not survive or flourish in your pond then it was a habitat problem and not because they were the wrong species. Remember you can not expect pheasants and quail to thrive in a bare or sparse field. They need AMPLE proper habitat and refuge areas from predators to flourish - same with grass shrimp.
If you order some of his shrimp please return with your feedback and keep us updated as to their progress in your pond/s. Others will be helped by your experiences.
