55. LOG PERCH 



PERCINA CAPRODES (Rafincsque) 



(Plate 33) 



The Log Perch is abundant almost everywhere in the Great 

 Lakes and streams of the south and west from Quebec to Lake 

 Superior and Iowa and south to Mississippi and the Rio Grande, 

 chiefly in swift gravelly streams of some depth. 



This species, represented by the subspecies zebra or the Mani- 

 tou darter, was very abundant in the lake in 1899-1900. In the 

 seining operations one oi' more examples were obtained in 143 out 

 of the 612 hauls made — 2,310 were obtained altogether, the great- 

 est number taken in any single haul being 310. During the prog- 

 ress of the work after 1900, however, not so many were obtained. 

 They ordinarily remain in shallow water near shore. They are 

 often seen during April and the early part of May. The first one 

 seen in 1901 was on April 6 ; this was found dead and was quite 

 full of eggs. From this time on till early May these fishes crowded 

 up in immense schools at the mouths of the various inlets of the 

 lake. Large schools were noted at the mouth of the ditch by Far- 

 rar's, at the mouth of Aubeenaubee Creek, and even at the mouth of 

 a tile by the depot grounds. When the fish were frightened they 

 darted rapidly up stream. On April 11, 1901, 29 were caught with 

 a dip-net at the mouth of Aubeenaubee Creek, and were measured. 

 The longest was 4.25 inches long and the shortest 3i inches; the 

 greater number were 3| and 3|- inches long. The females were 

 quite plump, and contained large numbers of eggs. The eggs were 

 rather pale in color, about 22 to the inch, and were very numerous ; 

 in one case the number of eggs in a single fish was estimated at 

 8,172. In darting up the streams they sometimes went with such 

 an impetuous rush that some would get stranded on the shore. On 

 April 29, a few were seen along the north shore and they were 

 abundant where springs entered the lake. Although they are not 

 ordinarily seen in small creeks, some were seen in the small creek 

 on the noi'th shore of the lake west of the Palmer House on
