We develop a simple analytical model of the acoustic reflectivity offish targets based on empirical observations in field and laboratory settings. It enables unbiased estimation of maximum dorsal aspect target strength in cases where individual fish are observed a minimum of three times in successive pings of a survey transect. The model results are consistent with observations of example fish targets of two demersal species. It promises improved estimates of target strength from field measurements.
