Recovery of foraging behavior of atlantic salmon exposed to a simulated commercial application of fenitrothion

Abstract

Fenitrothion is an organophosphate insecticide, used to control forest pests, that has often been sprayed in areas containing streams inhabited by Atlantic salmon (Salmo salar). This study simulated the exposure of Atlantic salmon during operational spraying of fenitrothion to determine if there would be effects on foraging behavior and the length of time required for recovery from any effect. The foraging sequence of the Atlantic salmon exhibited only minor effects of exposure, and the number of ingested prey was not affected. However, the reaction distance of the salmon to prey decreased significantly for those exposed to fenitrothion. The decline in reaction distance was still evident six weeks after exposure.

“…Fi?ial EIS -Horning Seed Orchard IPM Foraging behaviors were tested in Atlantic salmon exposed to fenitrothion for two 24hour periods separated by seven days. At concentrations of 0.006 and 0.21 mg/L, the reaction distance of the salmon to respond to prey decreased significantly (Morgan and Kiceniuk 1991).…”
