PPS is Death as a result of a crab being deprived of the resources he needs to adapt metabolically to conditional changes in his environment (humidity/temperature). The inability to adapt is influenced by the duration of depravation, on what elements were withheld that the crabs need to adjust to their environment (Mainly proper food, water, and light), and on the environmental conditions themselves. Death of a crab should not be classified as PPS outside of the initial established time frame of adjustment (30 days).
