468 U. S. BUREAU OF FISHERIES 



of commercial eggs purchased from dealers in Rhode Island and Massachusetts. 

 All of this stock was of fine quality and from it a large percentage of healthy 

 vigorous fry was produced. From a consignment of 129,000 rainbow-trout eggs 

 received in May from the Paris (Mich.) State hatchery, 117,800 fry were hatched 

 and distributed. 



Alpena (Mich.) substation. — Negotiations in progress at the beginning of the 

 fiscal year between the bureau and the city of Alpena led to the bureau's obtain- 

 ing a 50-year lease on 1 acre of city land containing a 2-story brick building and 

 a 1-story frame cottage, said property being used during the World War by the 

 Navy Department in the operation of a radio plant. As soon as the transaction 

 could be completed the hatchery was removed from its old location to the new 

 site, and installed on a brick foundation in the rear of the brick building, which 

 was fitted up as an office and an aquarial exhibit for the display of fishes common 

 to the region. 



From October 23 to December 4, 10,560,000 lake-trout eggs and 34,640,000 

 whitefish eggs were obtained over a territory extending from Black River to 

 Cheboygan. Most of these were of good quality, though some of the eggs from 

 around Cheboygan were poor. The partial failure in that field may probably be 

 accounted for by the faulty method employed by the fishermen in taking and 

 caring for the eggs prior to their delivery at the hatchery. In an effort to correct 

 this condition an experienced spawn taker will be assigned to oversee the work 

 near Cheboygan throughout the next collecting season. 



The delay occasioned by the removal of the hatchery building and the installa- 

 tion of new piping for a water supply necessitated the retention of the eggs for a 

 considerable time in egg cases and floating boxes. The percentage of hatch from 

 those in the cases was very good, as they could be given daily attention, but the 

 eggs in the boxes, held in the slip in the rear of the hatchery, were nearly a total 

 loss. In the distribution of the fry, which work extended from March 27 to May 

 25, all plants intended for waters within a comparatively short distance of the 

 hatchery were made by the local fishermen without expense to the bureau, thus 

 materially reducing the cost of the work. 



Charlevoix (Mich.) substation. — The high winds prevailing throughout the 

 spawning season in the fields covered by the Charlevoix substation tended to 

 reduce somewhat the collections of lake-trout eggs, though the loss was com- 

 pensated for in large measure by the substitution of improved methods in the 

 hatchery, so that the output of fry was nearly equal to the average of former 

 years. Eggs of this species were received at the hatchery from November 3 to 

 November 28, the season's take from the seven fields covered amounting to 

 34,361,000. In the course of the whitefish spawning period — from November 1 

 to November 30 — 22,960,000 eggs were taken in fields near Scotts Point, Naubin- 

 way, and St. Ignace. All of these were of good quality. 



In addition to its work with the commercial species, the station received and 

 hatched 11,000 landlocked-salmon eggs transferred from the Craig Brook (Me.) 

 station, and 40,000 steelhead eggs shipped from the Grants Pass (Oreg.) substa- 

 tion. The resulting fry were delivered to applicants at Frankfort, Menominee, 

 and Charlevoix, Mich. A filter for the improvement of the water supply was 

 under construction during the early part of the fiscal year, and while not fully 

 completed it was used to good advantage during the hatching season, removing 

 practicall}^ all slime and other impurities from the water. 



Put in Bay (Ohio) Station 



[David Davies, Superintendent] 



Shortly after November 1 the usual arrangements for obtaining whitefish 

 eggs were effected with the commercial fishermen operating in various parts of 

 Lake Erie, and on November 12 and 13 the field foremen visited the various 

 fields for the purpose of distributing the necessary spawn-taking outfits. The 

 season as a whole proved disappointing. Only a comparatively small catch of 

 whitefish was made by the fishermen collecting eggs for the station, and in its 

 efforts to obtain eggs in other parts of the lake the same conditions were en- 

 countered by the State. Up to the end of November it was generally believed 

 by the fishermen that a larger run of whitefish would occur, but at about that 

 time the weather suddenly turned cold, ice formed on the lake, and the fishermen 

 were unable to reach their nets, many of which were frozen in the ice. Eggs 

 were received at the station between November 18 and December 7, the total 

 for the season amounting to 138,280,000. Of these, the Port Clinton field fur- 

 nished 57,340,000, while the remaining eggs were derived from fisheries in the
