Alpena Statiox, Michigan (Frank N. Clauk, Superintendent). 



The occupancy of this station has continued under lease from Mr. 

 George IJ. Fletcher, of Alpena, and its suijply of water under contract 

 with the Alpena Water Company. The operations of the station, con- 

 sisting of the collection of the eggs of the lake trout for the North ville 

 Station and the propagation of the whitefish, were under the immediate 

 direction of Mr. S. P. Wires, foreman. Owing to the frequent and 

 severe gales of wind during the last of October and throughout Novem- 

 ber and December, fewer eggs than usual, of all kinds, were taken at the 

 spawning-grounds of lakes Huron and Michigan and Detour Passage. 

 The especially severe and cold gales m the early part of December on 

 Lake Michigan were the cause of an unprecedentedly small catch of 

 fish in that lake, which accounts for the small supply of whitefish eggs 

 taken from Beaver Island and Charlevoix. 



Lake trout. — The eggs of this species were obtained from thq spawn- 

 ing-grounds of Lake Huron on reefs in the vicinity of Thunder Bay 

 Island, and from Lake Michigan on reefs near the Beaver Islands off 

 Thompson. The first egg^, svhich were of the shoal-water race, from 

 Thunder Bay, were received about October 15, aud the work of collec- 

 tion was carried on till about the 1st of November, when a severe gale 

 tore up the nets and prevented its continuance. The eggs were devel- 

 oped at the station and then transferred to the North ville Station, seven 

 consignments being made between November 4 and December 14. 

 The season of collection represented two hundred and twelve days of 

 one man's time, during whicli 2,853,000 eggs were secured, as follows: 



From Mauistiqxie, Lake Michigan, seventy-five clays 2, 275^ 000 



From North Point aud Alpena, Lake Huron, seventy-five 



days 280, 000 



From Au Sable, Lake Huron, sixty-two days 298, 000
