cause when sewage is added bacteria feed on the organic matter,using a lot of dissolved oxygen. When this happens fishes have less oxygen to thrive on(they die). When they die it depletes oxygen levels more....so bacteria which do not require oxygen(anaerobically respiring bacteria)will increase cuz they can survive without oxygen
