Aquaculture is projected to be more easily adapted than wild fisheries to avoid excessive exposure to the physio-chemical stresses from acidification, warming and extreme events . In New Zealand, wild and cultured shellfish are identified as being most at risk from climate change . Changes in ocean temperature and acidification and the downstream impacts on species distribution, productivity and catch are projected concerns   that impact Māori harvesting of traditional seafood and the social, cultural and educational elements of food gathering  . Warm temperate hatchery-based finfish species  are projected to be the least at risk, because of well-controlled environmental conditions in hatcheries and temperature increases, which are expected to increase growth rates and productivity during the grow-out stage . For wild fisheries, multi- model projections suggest temperate and demersal systems, especially invertebrate shallow-water species, would be more strongly affected by climate change than tropical and pelagic systems  . In New Zealand waters, available habitat for both albacore tuna and oceanic tuna  is expected to widen and shift.
