332 Fourth Annual Report of the 



fish is not suitable for rearing in ponds; but evidence to the 

 contrary is at hand, and doubtless experiments in the direction 

 of pond culture for the pikeperch will be extended. 



The acclimation of the whitefish in Adirondack lakes and other 

 large lakes of the State has become evident, and it is practicable 

 to take vast numbers of eggs from stocked waters. The little 

 whitefish of Chateaugay lake has been added to the list of species 

 propagated and will undoubtedly be found adapted for continued 

 artificial culture. The fish was recently found in Big Clear lake 

 and the Adirondack hatchery found the young in Big Clear lake 

 in 1913 resulting from a plant made many years ago. 



The necessity of protecting our trout stations from pollution 

 by sewage and other causes is becoming more and more apparent 

 every year. The State should have full control of all its supplies 

 of spring water in order that they may be kept uncontaminated. 

 Several trout diseases have been traced to bacteria which thrive 

 only in polluted water. Epidemics have occurred, notably at 

 Caledonia and Bath, which have decimated the trout and which 

 could be entirely avoided by attention to the water supply. 



It has been suggested, and it is undoubtedly true, that ffood 

 results could be obtained in the planting of fish if the Commis- 

 sion should assign this work to its trained employees. Under 

 the present policy of appropriations, however, the method is im- 

 possible. It is to be hoped that the funds will be so increased as 

 to warrant not only a greater distribution but also an improved 

 system of planting. 



Recommendations for various improvements and repairs at 

 the stations have been made from time to time. The Adiron- 

 dack hatchery should have ponds or races to replace the decayed 

 wooden races now in use ; land should be acquired at Constantia 

 on which to build a boathouse for the proper storage of boats in 

 the service ; a new dam at the Oneida hatchery is greatly needed, 

 and a dam should be constructed on the Roelifi Jansen kill to 

 provide a new and improved water supply for the Linlithgo sta- 

 tion ; the Bath hatchery is greatly in danger of epidemics because 

 of the pollution of the principal spring supplying the rearing 

 races and ponds, and an outlay of $500 would relieve this con- 

 stant menace ; the field work on Long Island could be enormously
