THE WHITE PERCH. 37 
specimens of White Perch taken in the Delaware weighed, respectively, 
one pound nine ounces, one pound thirteen ounces, and two pounds one 
ounce. These were caught in ashad net in May, 1865, at the fishery 
opposite Trenton. The average adult fish may be said to measure eight 
inches and weigh from seven to nine ounces. He continues: ‘I believe, 
for reasons to be given, that the growth of the young is very rapid, and 
that the August Perch are young, hatched late in the preceding May and 
April; in June these August Perch measuring about two-and-a-half to 
three inches in length. . . . Ishould judge that spawning occurred 
_between May 10 and June ro, usually nearer the former than the latter 
date. This is based on the fact of having gathered very young fish, the 
age of which I guessed from the general condition and amount of develop- 
ment of the specimens. After the middle of June the White Perch are 
found in localities widely different; even waters with a dense growth of 
lily and river weed are found to contain them in apparent health and 
vigor—spots where the Rock fish could not live a day. Still later in the 
summer, as the young Perch become quite strong and of some size, the 
river, although in and above tide-water, fairly teems with them. At this 
season they go in schools, sometimes of large size. I have known of 
twelve, fifteen and twenty dozen August Perch being taken with a line in 
as short a time as from three to five hours. Fishing in this way a line 
with half a dozen hooks is used, and worms, sturgeon spawn or live min- 
nows are used as bait. These schools of small Perch I supposed to be 
broods of the preceding May, and that they kept together until late in 
November. They pass down to the salt water and there separate. Larger 
adult fish are not as restless as these smaller ones, and are found in deeper 
water, and usually in the tide-waters. In their feeding habits the White 
Perch agree very closely with the rock-fish. In all their habits, in fact, 
the two fish are much alike, and in the Delaware they are always asso- 
ciated, the most noticeable difference in their habits being the ability of 
the Perch to remain and thrive in warmer waters than the rock-fish is ever 
found frequenting.’’ 
Harris, in his ‘‘Game Fish of Pennsylvania,’’ writes: ‘* When taken 
with a skittered minnow or bright fly on a light rod, we do not hesitate to 
class as a game fish the White Perch. Large individuals are caught on 
the edges of the splatterdocks and in the eddies around the piers of the 
bridges spanning the numerous creeks that flow into the Delaware, the 
bait being a live minnow. At night, in the incoming tide, large Perch
