Avery, Kai, and Nora are having a debate about fish farming. Avery thinks the main advantage of maintaining high chloride levels in fish ponds is to reduce stress on fish from nitrite. Kai thinks it's to increase oxygen levels in the water. Nora believes it's to prevent bacterial infections, while their teacher suggests it's to enhance the growth of plankton. Who do you think is correct?

• Avery: Reduced stress on fish from nitrite

• Kai: Increased oxygen levels in the water

• Nora: Prevention of bacterial infections

• Teacher: Enhanced growth of plankton
