186 First Annual Report of the 



The frost of last winter opened a seam in the large reservoir, 

 along the east and south sides, from two to six inches wide. This 

 has been plugged with concrete, but I am afraid it will not stand 

 the frost. 



The total output of fry and fingerlings from Linlithgo hatch- 

 ery has been very satisfactory. On February 2, 1911, we re- 

 ceived 600,000 eyed brook trout eggs from C. A. Wolters, of 

 Weissport, Pa. From April 7th to May 3d we distributed 

 479,000 brook trout fry on 72 applications. 



The collection of shad eggs was carried on in the vicinity of 

 Rhinecliff". The eggs were bought from the fishermen at the 

 usual price of $10 per 100,000 eyed eggs. The hot weather in 

 May shortened the run; but we liberated 4,707,250 fry. On 

 September 23d, 100,000 fingerling shad were let out of the ponds 

 into the RoelifT Jansen. These were put into the ponds June 8th 

 and fed on water meal. When liberated they ranged from two 

 to six inches in length. 



The small mouthed black bass did well this year as compared 

 with last year ; 4,400 were sent out as fry on 14 applications and 

 6,750 as fingerlings on 22 applications. Twenty-five of 

 the adult bass were taken out of the ponds and put into Hayner 

 pond in Rensselaer county. 



We succeeded this year in raising a few calico bass. This is 

 the first of this species that we have been able to raise since they 

 were put into the ponds three years ago. On May 3d fifty-four 

 short-nosed sturgeon were put into a pond for rearing purposes. 

 They evidently spawned, but some bass escaped into the pond 

 and all the sturgeon fry were eaten by them. 



In getting food fish for the adult bass, we collected and hatched 

 360,000 yellow perch fry. We put seventeen long-eared sunfish 

 in a pond by themselves and took therefrom, on September 23d, 

 1,028 fine fingerlings. 



The total number of herring hatched was about 25,000,000. 

 The decrease in the herring output was due no doubt to the ex- 

 tremely warm weather in early June. The water being so warm 

 and the fish remaining in the nets so long before the eggs were 

 taken made the percentage hatched lower than usual.
