The outlook for the growth of koura aquaculture in the New Zealand domestic setting may be positive, with the potential for increasing demand in the restaurant and tourism fields. Export of koura to the international market may offer less potential due to competition from other established freshwater crayfish species such as the red swamp crayfish "Procambarus clarkii", of which the United States and China annually consume 34,000 tonnes and 88,000 tonnes, respectively.
