facilities fields of emphasis must be subject to change as the occasion arises. The areas of effort have been defined in the contracts along the following general lines. 1. To conduct studies on the immediate and continued effects of radiation and radioactive materials on living organisms. Aquatic life will be used for the most part, but fauna and flora existing adjacent to an aquatic environment also will be studied, as overlapping problems make such studies necessary. a. Laboratory studies of a fundamental nature on the effects of radiation and radioactive materials on aquatic life will be continued at the Applied Fisheries Laboratory. Field studies on the broad aspects of radiation and radioactive contamination of fauna and flora will be carried on at field laboratories where atomic bombs are tested, such as those at Bikini and Eniwetok Atolls. Studies on the effects of radiation and radioactive materials will be conducted in cooperation with the Aquatic Biology Group, General Electric Company, Nucleonics Division, Hanford Works. Areas of mutual interest will be explored so as to use the unique facilities and personnel available at each of the Laboratories in a complementary fashion. Laboratory Studies--Effects of radiation and radioactive materials on aquatic life (a) Effects of ionizing radiation on various stages of development of salmonoids. (b) Effects of ionizing radiation on organisms other than fish (c) Experiments with chinook salmon eggs and young in water of various temperatures (d) Experiments planned with various racial stocks of salmon on conditions for spawning and reproduction
