DISCUSSION The toxicity of ammonia to Macrobrachium larvae is inextricably linked to the pH of a solution, the total ammonia concentration present, and the proportions of that total which exist as either XH3 or XH4+. Undoubtedly other factors, such as dissolved oxygen and salinity, could be varied from optimal levels to further com- plicate the story of ammonia toxicity to this crustacean.
