Fur- ther decomposition brings about the third stage in which nitrites and nitrates are formed and act as fertilizing agents of the stream. A more abundant growth of plants and animals results, than is found normally. An interesting question then arises: does this added enrichment compensate for the loss farther upstream, and make possible a denser fish popula- tion? Before this question is answered another must be settled : is food a limiting factor for the number of fish in a stream? Observations on the Illinois River have "A recent report by the International Fisheries Commission reveals that, should the present rate of halibut fishing be con- tinued for any length of time, the indus- try will be reduced to insignificance. Accordingly, a movement to save it is well under way, and stringent regulatory measures have been proposed. "It is pointed out that not only has there been a fall in the abundance of fish, especially on the older banks, which has fallen to 16 per cent of the abund- ance in 1906, but there has been a de- crease in the size of fish, this being re- garded as especially serious because of.
