OPERATIONS AT NORTHVILLE AND ALPENA. 

 THE WHITEFISH WORK. 



823 



At "iSTortliville the first lot of whitefisb eggs was received November 

 IG and the last December 8. The first eggs were taken at North Bass 

 Island, Lake Erie, November 11, and the last at the same place, Decem- 

 ber 7. With the exception of a small lot furnished by Alpena after the 

 hatchery there was filled, the ISorthville supply was obtained wholly 

 from fisheries at North Bass, Middle Bass, and Put in Bay Islands, Lake 

 Erie. The total receipts at Northville from all sources amounted to 

 30,200,000. Some three or four million of these arrived after the hatching 

 jars were all filled ; but they were very successfully carried forward in 

 the shipping cases, at a temperature of 32° to 35°, until shipments and 

 losses in the jars had made room for them. The eggs began hatching 

 February 20, and comi)leted April 1 ; average period of incubation, 106 

 days. 



The water temperature varied from 32° to 54°, averaging about 40|o. 



At Alpena, the first eggs were taken November 10 and the last Novem- 

 ber 27, chiefly, however, from the 12th to the 20th. - Most of the supply 

 came from the pound-net fisheries at Scarecrow Island and Alcona and 

 the gill-nets of the tug Wayne Isbell, which was fishing on the shoals 

 at the mouth of the bay, though eggs were obtained from the tugs 

 Minna, Lida, and McKinnon, and the fisheries at Oscoda, Ossineke, 

 North Point, Misery Bay, Sugar Island, and Partridge Point. 



The water temi)erature was quite high — SO*^ to 55° — when the first 

 eggs arrived, but soon went down below 40°, and remained uniformly 

 low throughout the season, the average being about 35°. The eggs began 

 hatching April 8, and all were out May 16. Average period of incuba- 

 tion, 160 days. 



Eggs were shipped from Northville, as per the following table:
