percent, from a mean of 5.41 ± 0.57 mg 100 mg"-^ liver at the time of cap- 

 ture to 2.22 ± 0.39 mg 100 mg"^ (Table A-2) . At 20° Celsius, glycogen 

 decreased from 5.41 ± 0.57 mg 100 mg"^ to 0.098 ± 0.015 mg 100 mg"^, a 

 98.2-percent reduction over the 8-day holding period (Table A-2). 



The glycogen mobilization curve for white perch at both temperatures 

 was changed to linear form by straight-line regression. Based on this 

 regression line, mobilization at 10° Celsius occurred at the rate of 0.39 

 mg 100 mg"-^ per day. At 20° Celsius, mobilization almost doubled to 0.67 

 mg 100 mg "■^ per day.
