Book Description
Excerpt from University of California Publications in Zoology, Vol. 22: 1921-1923 The biology of fresh water is an attractive field for investigation both from the standpoint of ecology and from that of its practical bearings on the problems of fisheries. The fresh water plankton with its varying components forms a biological complex, or association of both plant and animal forms which have an intimate relation not only each to the others, but also to the varying factors of their environment, such as light, temperature, organic and inorganic substances in solu tion, and to seasonal change attendant upon the run-off from the watershed. The survey of San Francisco Bay undertaken by the United States Bureau of Fisheries in 1912 - 13 in cooperation with the University of California afforded an opportunity to initiate a survey of the plankton of the San Joaquin River, one of the principal tributaries of that bay. My position at Stockton as teacher of biology in the High School afforded some laboratory facilities and also a location near the head of tidewater where the ultimate contributions of the stream of the bay could be examined and where a variety of conditions were present, including both the main channel, and backwaters with varying rates of flow, as well as a canal much enriched by sewage.
