Hatchery losses of lake trout fry from areas of high DDT use led to a 4‐year study of the accumulation of the chemical in fish flesh and eggs from a number of waters in New York. Graphs are presented to indicate the range of DDT content of ether‐extracted oils from spawning female lake trout and a comparison of the amount in the oil of the adult with that in the eggs. No constant relationship was found. A procedure is described to relate the mass of the fry at the time of development of the syndrome associated with the mortality to the DDT in the ether‐extracted oil of the eggs. Graphical plotting of the concentration in the mass of the fry shows a relatively close relationship between the p.p.m. of DDT and the mortality.
