That's the first thing I thought of as well. Other invertebrates would presumably work too. There's already no taboo against eating crustaceans, and mollusks are generally acceptable as well. Though you probably have to restrict molluskivorism (that's my word of the day) to gastropods and other less complex organisms to avoid the ethical and cost problems that would come with cuttlefish, squid, and octopus farming.
