rounding the fish during fi-eezing and thawing. The 

 measurement of TOBEC values, however, did not pro- 

 duce consistent improvement in the predictabihty of 

 whole-body water content in fish from any of the five 

 data sets considered. This analysis indicates that 

 TOBEC procedures will not be able to predict with suf- 

 ficient accuracy the water content offish sampled fi-om 

 field situations and fi-ozen in water for later analysis.
