PEOPAGATION AND DISTRIBUTION OF FOOD FISHES, 1923. 69 



42,000,000 were of the subspecies. Heavy rains and melting snow 

 caused the bursting of the supply pipe of the smelt battery on April 

 29, necessitating the immediate planting of all eggs on hand. Fortu- 

 nately, all of them had about reached the hatching stage and plant- 

 ing at that period therefore occasioned little loss. 



One hundred adult smallmouth black bass, captured in traps in 

 Green Lake during July, 1922, were held in the station ponds until 

 fall and then delivered to an applicant at Norway, Me. These bass 

 inhabit Green Lake in considerable numbers, and being considered 

 undesirable on account of their tendency to prey upon the land- 

 locked salmon their removal is generally approved of by residents 

 of that section. 



GKAND LAKE STREAM (ME.) SUBSTATION. 



Apf>roximately 93,000 landlocked-salmon fry were on hand at the 

 beginning of the fiscal year 1923. Shortly before that date these fish 

 had been placed in the recently constructed ponds in the canal, 

 which was formerly used for the passage of boats in Grand Lake 

 Stream, and immediately afterwards the death rate among them 

 declined noticeably. The young fish were fed as frequently as they 

 would take it readily on a mixture composed of two-thirds beef 

 heart to one-third sheep liver finely ground, and late in July, after 

 45,000 of them had been liberated, it was observed that the re- 

 mainder were obtaining sufficient natural food to satisfy them. They 

 continued to grow rapidly and about the last of August all that 

 remained in the ponds were liberated in Grand Lake Stream as 

 fingerlings No. 3, the lot numbering 46,400. The first landlocked- 

 salmon eggs from Grand Lake Stream were secured on October 31 

 and the last on November 18, while the collecting season at Dobsis 

 Lake extended from the 1st to the 14th of November. In all, 423 

 female and 818 male fish were captured, from which eggs to the 

 number of 659,350 were taken. Of these, two shipments, aggregating 

 380,602 eyed eggs, were forwarded to the Craig Brook station. On 

 April 19 the Grand Lake Stream substation received 200,000 eyed 

 landlocked-salmon eggs from the State hatchery at Caribou, Me., 

 this shipment resulting from an agreement previously made with 

 the Maine commissioner of inland fisheries and game to insure the 

 return to parent waters of at least 75 per cent of the product of all 

 egg collections. Owing to flood conditions following the breaking 

 of the gate of the dam at the head of the canal on May 6, all salmon 

 had to be disposed of in the fry stage, the plants being made in 

 Grand Lake and tributary waters. 



In addition to the work with the landlocked salmon the station 

 handled a shipment of 131,666 commercial brook-trout eggs, which 

 were reshipped early in January from the Craig Brook station. 

 Owing to the accident referred to above all of them were liberated in 

 the advanced fry stage in Grand Lake and other local streams. 



The bureau's present policy of providing brook trout for Grand 

 Lake and neigliboring Avatcrs has already shown good results. It 

 was very' noticeable during the past season that good brook-trout 

 fishing was to be had in all the streams in this section, such waters 

 having formerly been denuded of that species. They now appear 

 to contain young brook trout in abundance, to the intense satisfac- 

 tion of the local oublic.
