Threadfin shad (Dorosoma petenense) impingement at 13 Tennessee Valley Authority electric generating facilities was monitored from August 1974 through June 1975 to assess possible mortality resulting from low water temperature. Concurrent experiments were conducted to evaluate the ability of cold-stressed threadfin shad to avoid impingement. In the laboratory, temperatures of 12$sup 0$C stressed threadfin shad and those below 8$sup 0$C caused high impingement mortality. At 5 of 12 fossil-fuel plants 85 percent or more of the annual impingement occurred when water temperatures were below 10$sup 0$C. At 4 plants impingement was not related to low temperatures. Impingement at Browns Ferry nuclear plant correlated generally with low water temperatures but individual impingement peaks were not consistently associated with temperature shocks. (auth)
