NSWC/WOL TR 77-90 



SUMMARY 



This report deals with the prediction of explosion injury to 

 fish with swimbladders and is part of a continuing study of the 

 effects of underwater explosions on marine life. Swimbladder fish 

 are particularly vulnerable to explosions, and this group includes 

 the majority of fish with sports and commercial value. This study 

 will result in an improved capability to predict such effects, and 

 will be useful in connection with the testing of new explosives and 

 warheads at sea. The case considered here is an application of 

 a general method developed at the Naval Surface Weapons Center to a 

 special test configuration in which the explosive charge is above the 

 water surface. 



This study is part of the ordnance pollution abatement program 

 of the Naval Sea Systems Command and was supported by Task 

 SEA 55001/19373. 



The author is indebted to George A. Young and Ermine A. Christian 

 for valuable suggestions during the course of this work.
