226 Thirty-fourth Annual Meeting. 
Mr. Harron: They did nicely until about ready to hatch, 
and then we had to transfer them to our collector courier, and 
they were placed in there as a solid mass, and hatched out 88%. 
3ut it requires constant care and attention to prevent smother- 
ing from dead corners of waters, that is, where there is not a 
complete circulation of water through the bottom of this tank. 
My idea is that the best way to handle perch eggs on a large 
scale, is in an open mouth jar with a spout attached so as to pass 
the young from the hatching vessel to the receiver. 
Mr. Buller: I agree with you, when you hatch the fry in 
large numbers. 
Mr. Titcomb: It is remarkably good work to handle 10,000 
fry in those troughs. What is the loss? 
A. The loss is very light. 
©. Do you count out your fish? 
Ate Messsite 
Mr. Titcomb: I think that is remarkable. 
Mr. Buller: I found very little trouble after the sac period. 
They took food very readily and I brought up these questions 
because | think the matter is very important to our inland lakes, 
Mr. Meehan: Did you not find this successful on a large 
scale, [ mean the mere hatching, by using the trays on the ponds 
as you describe, simply putting the eggs on the trays and allow- 
ing the trays to float loose on the pond? 
Mr. Buller: Yes. 
Mr. Meehan: There is another question and that is the 
temperature of the water. We found where the water was cold, 
just about the time the eggs were hatching out, a large number 
of fry died. It fell to 44° and little fish died by the thousand. 
Mr. N. R. Buller: I took some of the eggs over into the 
trout department, put them into those troughs, and the tempera- 
ture of my spring water at Pleasant Mount, is 47° ; and they all 
died in twenty-four hours.
