Figure 83. Pomolobus peudoharengus, from Potomac River, top, young, showing scales developing, 29 mm TI.,

tember, 50-79 mm;35 138 for October, 55-94 mm; 221 for November, 55-109 mm; 

 and 19 for early in December, 60-79 mm TL. In Chesapeake Bay, young that ap- 

 peared to be in their first winter, as judged from their small size, were 75-140 mm in 

 January, 80-1 14 mm in February, and 80-145 mm in March. The young fry taken 

 in the Bay during the winter varied so widely in length that it is clear they represented 

 more than one year-class. The 262 older fish taken during the winter ranged between 

 1 15-224 mm, or 1 15-194 mm, if the three largest examples are excluded. 



The foregoing data seem to show that the young of this species grow to a length 

 of 55—109 mm (2.20-4.36 in.) while in fresh water, to about 65-145 mm (2.6- 

 5.8 in.) at one year of age, and to about 1 15-195 mm (4.6-7.8 in.) at two years of 



35. The largest young of the season evidently are not represented in this collection.
