Hemolymph osmotic pressures and chloride concentrations were measured in red swamp crawfish Procambarus clarkii at harvest and after storage in a cooler in March and May. Male and female crayfish had similar hemolymph concentrations regardless of treatment, and osmotic pressure and chloride levels were generally stable for a storage period of up to 5 d after harvest. These data suggest that trapping or storage in a cooler causes no dramatic physiological change in red swamp crawfish.
