∙ 11y agoCrayfish or Crawfish depending on your region have the unique ability to absorb quantities of oxygen out of water as long as there is 100% humidity. As long as the gills are moist, the crustatean can obtain the needed oxygen. The other consideration is keeping them cool. They are cold blooded so their circulatory systems slow drastically when the temperature is lowered. Therfore, crayfish farmers/retailers ordinarily keep 40-50lb sacks of crayfish in a refridgerated storage after having rinsed the crayfish well with water. They can live for several days in this condition. Personally, when I catch them for a party etc, I use a large ice chest partially filled with ice, a piece of carpet or towel to keep the crayfish from direct contact with the ice and close the lid.
