The larger size of the Southern PK shrimp could IMO be easily due to the longer growing season for these shrimp. These shrimp since they are invertebrates could grow larger when they have a longer growing season? I would like to get a few preserved shrimp individuals to verify the species using close microscopic analysis of necessary features for species identification. Does anyone have some of these Gulf coast area PK shrimp to send me?? As canyon says another easy way to determine cold tolerance is to put some in the refrigerator at 39F to 40F for a week or two.
I brought mine from near the coast and they have done well in oakwood . We have had skim ice over most of the pond and they made it
