tank. This species enters slightly brackish water ; it grows to

Catostomus nigricans Les. 



Black Sucker. 

 The black sucker is also called by such names as hog molly, 

 stone toter, etc. The scales are larger than in the previous 

 one; there are about fifty on the lateral line. The back is 

 brassy olive with dark cross blotches in younger specimens. 

 The lower fins are red. Dorsal 11, anal 7. Length two feet.

 Moxostoma macrolepidotum. 



Erimyzon sucetta {Lac). 



Chub Sucker. 

 Moxostoma oblo?igum AucT. 



A rather common fish; broader than the brook sucker.

 above, more yellowish to silvery below ; the young have a 

 broad black band along the sides and one along the back. 

 Dorsal 11 to 13. Scales 43-15. This fish bears captivity better 

 than the other suckers and is somewhat livelier in its habits. 

 I have seen it taken by snaring with a wire noose attached to 

 a stick. It grows to a length of nine inches.

 A heavier fish than the ordinary sucker. The mouth is

 on the sides, the lower fins and tail fin flesh red. Dorsal 12, 

 anal 7. Scales 5-45-4, large. Air bladder in three parts. (See 

 also Catostomus nigricans above.)
