Insulated and ventilated shellfish storage

An insulated container packed with live crustaceans for storage, comprising:

• a bottom, a plurality of walls, and a lid wherein the bottom, the plurality of walls, and the lid comprise an insulating material and define an interior space;
• and
• the live crustaceans packed in the interior space in a vertical orientation substantially perpendicular to the bottom,
• the plurality of walls comprising at least one ventilated wall having a plurality of carbon dioxide (CO2) ventilation openings at a height on the at least one ventilated wall above an interior surface of the bottom, and
• wherein the height on the at least one ventilated wall of each of the plurality of CO2 ventilation openings is between 1 cm and 5 cm above the interior surface of the bottom and the height of each of the plurality of CO2 ventilation openings is selected to align at or be below a lowest part of gills of the live crustaceans packed in the interior space, wherein the plurality of CO2 ventilation openings remain in an open configuration and are the only openings in the insulated container when the insulated container is in a closed configuration with the lid contacting the plurality of walls, wherein each of the plurality of CO2 ventilation openings has a diameter that is approximated 7 millimeters, and wherein the plurality of CO2 ventilation openings allow CO2 produced by the live crustaceans to escape the insulated container and avoid leakage of water from the interior space of the insulated container that is packed with the live crustaceans.
