TABLE 2.1 

 CRITERIA FOR DAMAGE TO FISH 8 



(0) No damage 



(1) Only light hemorrhaging, principally in the tissues 

 covering the kidney. 



(2) Gasbladder intact, but with light hemorrhaging throughout 

 the body cavity with some damage to the kidney. 



(3) No external indication of damage but with the gasbladder 

 usually burst. Hemorrhaging and organ disruption less 

 extreme than in (4) and (5) but with gross damage to the 

 kidney. 



(4) Incomplete break through the body wall but with bleeding 

 about the anus. The gasbladder is almost invariably broken 

 and the other organs damaged as noted under (5) . 



(5) Rupture of the body cavity. The break is usually a slit 

 just to the side of the midventral line. Associated with 

 this severe damage is a burst gasbladder and gross damage 

 to other internal organs. The abdominal contents are 

 often completely lost or homogenized.
