Oiii'idii Lake fishes 313 



wi.^c. Ji ihcii >ucks ujj the sliinc between the stones an<l with it obtains immature 

 insects." Kvermann and Clark ('20, p. J<;5 ) found the stomachs of two sjiecimens 

 filled with nuid and animal and vej,'etable remains. The food of nine specimens 

 from Winona Lake, Indiana, was examined by DeRyke ('22, p. 39). Chironomus 

 larvae were the i)rincipal food remains, while aquatic oligochaete worms, ephemerid 

 nymjihs, silt, sand and debris made up other material. Greeley ('27, p. 57 ) reports 

 on the food of a younjj Hog Sucker nearly an inch long, as composed of 95/0 

 small crustaceans (Cliydoriiiac) and 5% midge larvae; rotifers and diatoms 

 formed a trace of the food. 



Distribution Records. The two s]>ecimens (Xos. 360, 486) are from the 

 Hrcwerton market, f)resented by Mr. H. X. Coville. Each is alwut a foot long. 

 No. 365 includes 3 market specimens; Xo. 548 is a specimen taken by us al>out 

 2j^ miles up Chittenango Creek, in 3 or 4 feet of fairly rapid water, over a ri,>cky 

 bottom. It is alK3Ut a foot long. One young si>ecimen ( Xo. 4270) was taken at 

 Sylvan Beach September 9, 192". 



Enemies and Disease. Our siHfcimen Xo. 548, from Chittenango Creek, was 

 nearly dead when taken, had a small injury on its belly, and may have l)een 

 diseased. 



Economic Relations. The Hog Sucker is of little economic value on account 

 of its small size, many bones, and the difficulty of capturing it in numbers. Ever- 

 mann ( *oi, p. 340) says they are used to some extent as liait in still-fishing, but are 

 not of much value. They live well on the hook an<l are pretty active, but they 

 are too dull in color and too prone to seek the bottom.

Erimyzon sucetta oblongus (Mitchill). Ciub Sicker. (See Figure ii><).) 

 This is largely a stre.im fish. It is not abundant and probably its main value, 

 aside from its use as bait, lies in its serving as food for other more valuable fish. 

 It may Ik- distinguished from other suckers of Oneida Lake and vicinity !)y the 

 absence of the lateral line. In the water it appears somewhat like a perch with 

 dark vertical bars on its sides, but the single dorsal tin and inferior mouth will 

 readily distinguish it fronj that fish. Hie young lack these liars but have a 

 conspicuous, bl.nck, lateral band on each side. 



Hreediuf] Habits and Life History. \'ery little is recordctl on the brceiling 

 habits of this fish. Forbes ami Richardson ( 'oi). p. 82) note that, "In onlinary 

 seasons it s|)awns in central Illinnis in .\pril and M.iy. Riixr females were taken 

 at ll.ivana .\|iril 10. i8<k), and females with ripe ovaries from March 20 to 

 .\|)ril 15." Wright and /Mien ('13. p. 4) give the breeding season in small 

 streams at Ithaca, X. ^'., as .\pril to May 15. The nialcs in spring usually show 

 three large tulnrrcles on each side of tlic snout, an<l the anal rays are tulicrculatetl ; 

 these characters only apjn-ar in males over five inches, and until the maximum 

 size (eleven inches) is attained, .according to l-'owlcr ('12. p. 475). One of our 

 market specimens ( Xo. 365) from Brew«rt<>n. taken in Ma\. agrees with I"owIer"s 

 description. It is abdut 10 inches long
