However, the CO2 treatment showed lower lactate and cortisol response compared to asphyxia in ice. In terms of quality, differences between methods WebFirst, what we call a chance mutation—a tiny genetic change—occurred in that one notothenioid species. Its DNA allowed for the production of a special protein, a protein that prevents the fish from freezing. The way this—this antifreeze protein—works is: it binds to any ice crystals that form inside the fish.
