length distribution ranging from 1 to 5 centimeters (0.4 to 1.9 inches). The growth 

 during the late spring and summer of 1926 was rapid, but extended spawning oc- 

 curred from April to October, resulting in a wide length-frequency distribution. By 

 the end of November, 1926, this O class, approaching its first winter, had attained a 

 modal length of about 13 centimeters (5.1 inches), the length distribution being from
