bobad, you sure yours are P. kadiakensis and not P. paludosus? Louisiana is a warmer climate so P. paludosus would do well there...

If they are P. kadiakensis I'm gonna beg you to scoop up some and ship em to me so I can experiment with them... I have a barren pond I am going to turn into a forage pond this year and would like to start by stocking it with some P. kadiakensis. I'd like to do this before they spawn so I can get a good year class hatch...

I have seen in person P. Pugio, P. Valgaris, P. intermedius and P. paludosus and can't tell the difference! About the only way I can tell them apart is by where I catch them... They just vary by their habitat preference. Just isn't much literature out there on grass shrimp, particularly P. kadiakensis.
