A 1-page memorandum from W. R. Peavy, Jr., a fishery biologist with the Florida Game and Freshwater Fish Commission, regarding the May 1962 Lake Apopka fish kill. The memorandum revises the earlier estimate of fish killed, found in Harold L. Moody's memorandum toO. E. Frye, Jr., Assistant Director of the commission, from 50,000 lbs to 120,000 pounds. Frye states his belief that DDT (dichlorodiphenyltrichloroethane) and parathion sprayed from agricultural aircraft were responsible for the kill. Samples of the dead fish were shipped to the University of North Carolina for analysis by Dr. Charles Weiss, Professor of Sanitary Science. The results were inconclusive regarding pesticides, as the cause of the kill due to decay suffered in transit. However, some samples did show evidence of exposure to pesticide.

A letter of correspondence from Harold L. Moody, fishery biologist, to O. E. Frye, Jr., Assistant Director of the Florida Game and Freshwater Fish Commission. The letter discusses a fish kill on Lake Apopka in May 1962. Moody reports that eyewitnesses observed an agricultural spray plane disperse pesticides over the lake shortly before the fish kill began. Fish kills are usually associated with low levels of dissolved oxygen in the water. Moody notes that his samples showed the oxygen levels to be low, but rather than being evenly dispersed through the lake, the fish kill was concentrated at the north shore adjacent to the farming operations. Moody also notes the presence of dead reptiles and amphibians not normally found during an oxygen-related kill. The fish kill was estimated at 50,000 pounds, at that time the largest fish kill of 1962.
Moody, Harold L.
