A program was initiated to study the effect of sonic boom on fish and fish eggs during critical stages of development. During the development of fish eggs they reach a critical period where they become sensitive to vibration or disturbance. This program was designed to determine if the disturbances caused by sonic booms could have a detrimental effect during this period. It consisted of both field and laboratory tests conducted at several National Fish Hatcheries NFH. Fish eggs from both trout and salmon were reared in the normal manner, except that when they were in their most critical phase of development they were exposed to sonic booms produced by military airplanes. Egg and fish fry mortalities from exposed groups of eggs were compared to those for control groups of eggs spawned at the same time. These comparisons indicated that the sonic boom exposure caused no increase in mortality.
