JOHNSON and SALOMAN: AGE, GROWTH, AND MORTALITY OF GRAY TRIGGERFISH 



The weight-length relationships for gray trig- 

 gerfish computed for the equation W = ah , 

 where W is weight in grams and L is FL in 

 millimeters, were as follows: 



males W = 6.7105 x 10 6 L 3187 , 

 n = 169, 



females W = 1.393 x 10" 5 L 

 n = 167, 



3.065
