Transporting or storing live crustaceans on ice or in ice water is also forbidden; they must be kept in their natural environment (e.g. seawater) and killed or tanked within a limited time of arrival. The rule is not limited to restaurants or fishmongers - the underlying cruelty prohibition applies broadly to anyone killing the animal.",
