Chub-sucker {Brimyzon succtta oblongus) 



The fry of this species, ^ to i^ inch long, were abundant in 

 Quiver Marshes in late May and early June of 1910 and 191 1. The 

 fry swim in schools of fifty to a hundred or less, at about the same 

 level as bass fry, and their coloration, owing particularly to the black 

 side-stripe, is such that they are not always readily distinguished at 

 the first glance from fry of large-mouthed bass. 



Yellow Bullhead {Ameiurus natalis) 



Examination of market specimens. May 19, 1910, showed the 

 yellow bullhead well advanced — probably within less than a week of 

 their spawning time. June 3, 191 1, eggs ran from market speci- 

 mens examined. That spawning was in progress was indicated also 

 by a great decrease in the trot-line catch within the few days pre- 

 ceding. 



Speckled Bullhead {Auiciunis iicbidosus) 



May 19, 1910, market specimens of the speckled bullhead uni- 

 formly appeared considerably less advanced than the yellow and 

 black bullheads. May 27, 19 10, a female brought in by Allen from 

 Deep Slough May 23, spilled eggs in the tub in which she had been 

 placed for observation. 



May 28, 1910, trot-liners generally quit work because of failure 

 of the bullheads to bite while spawning. May 31, 1910, we found 

 a nest in Quiver Marshes containing a hundred or so recently hatched 

 fry, probably not much more than three days old, the yolk sac still 

 being large. This nest was in water 2^ feet deep, among Cerato- 

 phyllum and rushes. It was guarded by a 14-inch male, who al- 

 lowed the water-glass to be pushed down almost in contact with his 

 back. 



In 191 1 some specimens in market had eggs running as early as 

 May 14. Between May 27 and June 3 they were reported by trot- 

 liners generally as spawning. On July 2 we found two schools of 

 100 young each, i^ inch long, attended by the male, in Becks' ponds 

 and Danhole's field. 



Black Bullhead (Anicinrus melas) 



May 19, 1 9 10, market specimens of black bullheads were in about 

 the same condition as the yellow bullhead already mentioned. They 

 were apparently within less than a week of spawning.
