Having mislaid my notes on this species, I am compelled to use the very brief description 
given by De Witt Clinton. It is a very distinct and beautiful species. According to Mr. 
Clinton, it is nearly equal to any fish that swims, for exquisite and delicious food. It is among 
fishes what the grouse or canvass back duck is among birds: the flesh is fine, white and 
delicate. It appears to be peculiar to Otsego lake, and is daily decreasing in numbers. It 
is rarely taken by the hook, but has been taken by the seine to the number of five thousand 
at a draught.
