 was 28.3 cm. and .5 lb. 



The average length and weight of 5 females (from 29 to 31 cm. long)

Twenty-five examples (sex and length not recorded) averaged .54 lbs. 

 each. 



29. Pomolobus aestivalis (Mitchill). Glut herring. 



FAT-BACK, BLUE-BACK. BLACK-BELLY. 



It is reported that there is a falling off in the run of this species from 

 that of the past three or four years. 



This year (1912) this species was first taken in the Elk River on April 

 11th, but did not appear in any considerable numbers until the 16th. 

 The run reached its heighth on April 27th, and by May 8th was almost 

 over. 



The average weight of 25 males (26.5 to 31.5 cm. long) was .56 lbs. per 

 fish. 



The average weight of 50 females (27.5 to 34 cm. long) was .68 lbs. per 

 fish. 



The average weight of 99 fish of both sexes (27 to 34.5 cm. long) was 

 .61 lbs. per fish. 



Of the many thousand individuals seen the majority had a single black 

 blotch at shoulder, but individuals with a row of from three to nine 

 blotches were not uncommon, and a considerable number were seen 

 which showed traces of a double row.
