GREEN LAKE (ME.) STATION AND SUBSTATION. 

 [John A. STcmY, Superintendent. J 



Operations in this field were confined to the work at the main sta- 

 tion and the substation at Grand Lake Stream, Me., the collecting 

 station at the Fish River Lakes being abandoned in favor of the 

 Maine State Fish and Game Commission because of insufficient funds. 

 The species handled involved the landlocked salmon, the brook trout, 

 the smelt, and the small-mouthed black bass. 



GREEN LAKE (ME.) STATION. 



The work in connection with the landlocked salmon was taken up 

 in October, when a pound net was placed in Green Lake for the 

 capture of the spawning salmon. Fishing was continued from Oc- 

 tober 17 to November 12, and during the period 171 adult fish were 

 taken. Of these 114 were females and 57 males, and 227,525 eggs 

 were obtained. In addition 25,000 eggs were supplied the station 

 from the State's hatcher}^ at Oquossoc. Of the local collections 

 70,000 were shipped in the eyed stage for convenience in distributing 

 fry and fingerlings to the various applicants in the State, and smaller 

 numbers were supplied to applicants in other parts of the country. 

 The remainder, with those received from the State, were incubated 

 at the station for the replenishment of local waters. 



Eyed brook-trout eggs to the number of 103,000 were acquired by 

 purchase from commercial dealers, and an additional lot of 75,000 

 was received from the Pennsylvania Department of Fisheries and 

 Game. The resulting fry were distributed in the waters of the 

 State. 



The efforts made to collect spawning smelt for propagation at this 

 point were not successful. The cold rains occurring at spawning 

 time apparentl}^ caused the fish to desert their customary spawning 

 places in the tributary streams. An investigation of other ponds 

 in the locality revealed similar conditions. The 300,000 eggs of this 

 species obtained were incubated with but little loss. 



Because of windy weather and the unusual depth of water in which 

 nest-building occurred, but little was accomplished in obtaining 

 small-mouthed bass fry from Green Lake waters. Some 22,000 were 

 taken and supplied to applicants in other sections of the State. Fish 

 of this species are not considered desirable in Green Lake, which is a 

 natural habitat of the more highly prized landlocked salmon, and 

 the removal of the bass fry for introduction into other more desir- 

 able waters meets with the approval of the local interests. 



On the recommendation of the bureau the Green Lake station was 

 closed as a permanent fish-cultural plant at the end of the fiscal 

 year. It was estimated that not less than $25,000 would be required 

 to replace the dam and water-supply flume, which were rapidly 

 falling into decay, and in view of the fact that the water available 

 at this site is of an inferior quality at best the discontinuance of 

 the station seemed the only practical course to pursue. The bureau's 

 property at Green Lake will be guarded by a custodian, and the 

 more important items of fish-cultural work formerly prosecuted 

 there will be continued as an auxiliary to the operations of the 

 Crais: Brook station.
