KUDO ET AL.: TEXTURE QUALITY OF PACIFIC WHITING 



6 to 8. Fish infected with white pseudocysts to the 

 degree of 26 to 50 counts (average for the six areas 

 in each fish tested) resulted in 1 out of 50 fish 

 tested with a sensory texture score of 2. Thus, 2% 

 of the fish in this category must be regarded as too 

 soft and are organoleptically unacceptable (Table 

 1). In the sample of 562 fish, 25 specimens were 

 found with white pseudocyst counts ranging be- 

 tween 51 and 75, none of which were judged to 

 have a texture score of 2 or lower. However, note 

 that 11 of 25 (449c) fish samples were soft tex- 

 tured. When the white pseudocyst counts were 76 

 or higher, nearly all of the fish were soft or abnor- 

 mally soft textured. 



The frequency distribution of sensory texture 

 scores vs. black pseudocyst counts (Table 5) does 

 not show the same relationship that intensity of 

 white pseudocyst infection had on sensory texture 

 (Table 4). This becomes evident after examining 

 sensory texture scores for fish with black pseudo- 

 cyst counts of 1 to 25 (Table 5) when the entire 

 range of texture scores is represented. 



Note, however, that the observed distributions 

 of white and black pseudocysts differ. For exam- 

 ple, of the 98 fish with pseudocyst counts exceed- 

 ing 50, 81 had white pseudocysts but only 17 had 

 black pseudocysts. Also, for Pacific whiting with 

 counts >100, 37 of 45 (82%) with white pseudo-
