Despite the occurrence of populations of the anomuran prawn Callianassa kraussi Stebbins in salinities as low as one part per thousand, investigation showed that a minimum salinity of 25-30 parts per thousand was required for successful development of the eggs and larval stages. Dispersal into areas of low salinity and maintenance of these non-breeding populations is accomplished by migration of the early post-larval stages from higher salinity areas.
