ryjohn - Good idea of checking the lower limit temperature of PK shrimp by putting them in the refrigerator or iced water and monitoring the correct temperature. I will try that for my PK shrimp next year. My strain of PK shrimp came from Lake Erie marshland. The northern population may have developed an adaptation to cooler winter waters than those shrimp in the southern states?
