The fish show a tendency to keep out of the creeks in weather of 

 the character prevalent in the spring of 1913. 



Very few if any pikeperch were stolen from our nets or along 

 the shores of Scriba Creek, which is due very largely to the efficient 

 and continuous watchfulness of the game protectors who were de- 

 tailed to help protect the fish during the spawning season. 



The yellow perch, for some uncountable reason, did not spawn 

 on their usual grounds in 1913. 



NOTES ON SPECIES 



Short-Nosed Sturgeon 



On June 13, 1913, a collection of snails, which form a large 

 part of the food of the short-nosed sturgeon in one of the ponds 

 at the Linlithgo Hatchery, was sent to the Assistant Secretary of 

 the Smithsonian Institution, Washington, through whose kind- 

 ness they were identified as representing the following species : 



Vivipara contectoides, Binney; Lymnaea catastopium, Say; 

 Physa ancillaria, Say; Planorbis trivolvis, Say. 



Shad 



The first eggs, five quarts, were taken in the Hudson river 

 May 7, 1913, for the Linlithgo Hatchery. 



At the Linlithgo Station, in 1913, the rearing of shad from fry 

 was unusually successful. On September 16, the foreman reported 

 that the fish are the finest he has ever seen. There are about a 

 half million in the pond. It has cost about thirteen dollars to 

 feed them thus far, and the total cost for the entire season will 

 scarcely exceed twenty dollars. The water is too low now to float 

 them out into the creek, and they will be kept until the fall rains 

 increase the supply. A few of the shad have been killed by the 

 big waterbugs, Belostoma; but the losses from all causes were very 

 trifling. 



Lake Trout 



At Silver Lake, in Franklin County, one of the employees of the 

 Adirondack Hatchery collected between five and six quarts of 

 eggs' of this trout up to October 20, 1912; but he had great diffi- 

 culty in obtaining male fish to fertilize the eggs.
