Abstract : The experiment described in this report was designed to validate a theory of damage by underwater explosions to swimbladder fish. The theory is based on the dynamics of the swimbladder under the influence of an underwater explosion shock wave. Caged fish of twelve different species were paced in the vicinity of explosions. The pressure-time history at each fish location was recorded, and the damage to each fish specimen was determined by dissection. Pentolite charges weighing approx. 0.6 and approx. 32 Kg were detonated at depths of 3.0 and 9.1 meters. Fish were arrayed to depths of up to 30 meters. Six shots were fired. This report describes the experiment and presents the fish damage and pressure-time data. Laboratory work to determine the time necessary for fish to acclimate to various depths in the water column is summarized. The analysis of this data in terms of theory will be presented separately.
