1921, 20 miles S. by W. of Presque Isle Light, Ontario, in 40 to 50 fathoms (records 



4 and 5), but the percentage was not ascertained. Few specimens were taken on 

 November 23, 1917, off Winona, Ontario (record 1); on June 29, 1921, 13 miles 

 E. Yi S. of Bronte, Ontario, in 40 to 50 fathoms (record 2); on June 23, 1921, and 

 July 21, 1921, 3 miles north and 2 miles north of Wilson, N. Y., in 30 and 20 fathoms, 

 respectively (records 14 and 18); on September 4, 1923, S}4, miles W. by N. Yi N. 

 of Oswego, N. Y.j in 70 to 75 fathoms (record 10); and on August 30, 1923, 14 miles 

 west of Sandy Pond, N. Y., in 60 fathoms (record 7). The scarcity of fish in the 

 3-inch nets lifted on July 13, 1921, off Sodus Point, N. Y. (record 12); on September 

 1, 1923, off Nine-Mile Point, N. Y., in 30 fathoms (record 9); on July 11, 1921, 



5 miles NNW. of Nine-Mile Point, N. Y., in 25 to 35 fathoms (record 8); and on 

 August 24, 1923, 9 miles west of Sandy Pond, N. Y., in 25 to 28 fathoms (record 6), 

 shows nothing conclusive about the abundance of the species, as the mesh of such 

 nets is too large to take the species. Similarly, the rarity or absence of specimens 

 from the 4}/£ and 4% inch whitefish nets is of no interest in this connection because 

 the fish could only have become entangled accidentally in such netting. 



Thus, the few observations on record show that the bloaters, though occurring 

 between the depths of 16 and 75 fathoms, are most abundant, at least in summer, 

 between the depths of 50 and 65 fathoms. 



BREEDING HABITS 



Except for a single example found among the spawning herring collected off 

 Winona, Ontario, on November 23, 1917 (record 1), and one received from J. R. 

 Dymond, of the University of Toronto, taken off Port Credit, Ontario, on March 

 28, 1926, no specimens of the species were seen between the dates of September 

 4 and June 10. None of the individuals collected as late as September showed any 

 approach to sexual ripeness, and the fish collected in early June clearly had not 

 spawned recently. The specimen taken on November 23, 1917, was a male with 

 pearl organs and was therefore ready or nearly ready to spawn. The one taken 

 on March 28, 1926, was a spent female. The spawning season, then, probably falls 

 sometime between these dates.
