DARK: AGE AND GROWTH OF PACIFIC HAKE 



Growth in weight was determined by applying 

 the length-weight equations: 



log W = -1.45990 + 2.55618 log L for males, and 

 log W = -1.68944 + 2.69509 log L for females 



to average length-at-age data. By age 3, males 

 have grown to about 50% of their total weight at 

 age 11, and females to about 40% of their total 

 weight at age 11. At 11 yr of age females weigh on 

 the average 200 g more than males. Males attain 

 an average weight of about 1,015 g by age 11 and 

 females reach an average weight of 1,374 g by 13 

 yr of age.
