CALIFORNIA FISH AND GAME. 319 There are three marked phases of river pollution. In the earliest the organic con- tents are unchanged and are eaten by adult scavenger fishes. No young fishes of any kind are found in this section. As decomposition takes place the clean water animals disappear and are replaced by sewage fungi, sludge worms, midge larvae. It is easily seen that the bottom condi- tions are worse than those of the water since the water is purified by contact with the air, whereas the stream bed is contin- ually being coated deeper with filth. The gases forming on the bottom cause worm- shown that it has an abundance of food for a larger stock of fish than it carries. Then one must conclude that food is not a limiting factor and that an added sup- ply does not increase the number of fish.— Genevieve Corwin, September 4, 1928.
