Table 1 



Yellow perch individual water content (gl from measurements laet) and predicted (pred) from regression functions. TOBEC is the 

 average scanner conductivity index (based on five consecutive measurements). "^DWTis the percentage dry weight and is equiva- 

 lent to: |( I wet weight - water I )/wet weight) x 100. Values in parentheses are percentage errors (PEs) referring to water (g) and 

 '/f'DWT, and are equivalent to l( I actual - predicted I )/actual| x 100. 



' Predicted (predl values from the regression function with wet weight <g) and TOBEC as the independent variables. 



- Predicted (pred) values from the regression function with wet weight (g) and square root transformed scanner conductivity index as the indepen- 

 dent variables.
