This paper describes an acoustic survey on small herring in a fjord in
Northern Norway which was carried out three times during the same
night. The survey speed was 4 knots during two of the survey runs and
once 8 knots.The integrator output for each of the surveys showed a
variation of less than 10% of the mean integrator output.
