352 FIFTEENTH ANNUAL REPORT OF THE 



in the least they would die. Also if eggs are taken from the tullibee it is 

 useless to return it to the water because the fish will not live. 



Smelt 



The period of incubation of the eggs at Cold Spring Harbor in the 

 early spring of 1909 was from twenty-five to twenty-seven days. The 

 season was wonderfully successful, the output of fry having been 226,- 

 000,000. 



Maskalonge 

 On April 30, 1909, Mr. R. R. Brown, in charge of the hatchery at Bemus 

 Point, reported that just when the eggs were becoming plentiful a snow 

 fall of eight to ten inches, turning into rain, suddenly raised the water in 

 the lake so high that it went over the top of the nets and interfered greatly 

 with the catch of spawning fish. On May 28th Mr. Brown lost a large 

 number of maskalonge fry which he thinks had been kept in the jars too 

 long after the eggs were hatched. 



The eggs of this fish, with the exception of three or four jars, in the 

 Chautauqua hatchery, all hatched out in three or four days. It was found 

 impossible to carry the fry in the boxes. It is probable that they were 

 kept too long before the transfer to the boxes. 



On May 30th the fry began to die in the morning. Mr. Brown stated 

 that they showed no preliminary symptoms but died suddenly. He noticed 

 a bad smell to the water from Chautauqua Lake, but is not certain whether 

 this caused the death of the fry. 



On May 17th Mr. Brown observed that the brook trout in the cement 

 ponds at the hatchery were dying from no apparent cause except that some 

 oil got into the water from the engine. The mortality among the trout 

 ceased as soon as the use of the lake water was abandoned. 



Trout Perch 



On March 19, 1909, Mr. C. L. Klages sent from Walloomsac, N. Y., 

 two specimens of this little fish. He wrote that there are a good many of 

 them in the Walloomsac River. By some persons the fish was mistaken
