REPORT OF COMMISSIONER OF FISH AND FISHERIES. 55 



January 28. The hatching season closed on March 5, and the distribu- 

 tion of fry was made during March and April by the Fish Commission 

 cars and was very successful. 



From the brood stock of Loch Leven trout 78,000 eggs were taken, 

 the first on October 28 and the last December 12, the 117 females 

 stripped averaging 667 eggs to the fish. These eggs were of extra 

 fine quality, and from them 75,000 fry were hatched and planted, a 

 trifle over 96 per cent. They were the first eggs in the house to 

 hatch, beginning January 4 and continuing until February 25. The 

 distribution of the f r}- was made between March 12 and 18. 



From the Neosho and Manchester stations 105,012 rainbow eggs 

 were received, from which 86,000 fry, or about 82 per cent, were 

 hatched and planted. This low percentage was due to the fact that 

 some of the eggs were not in good condition when received. The first 

 eggs hatched February 19 and the last March 12, and by April 17 the 

 distribution of the fry had been completed. 



From a stock of 3-year-old steelhead trout, which had been hatched 

 and reared at the station, 111,600 eggs of fine quality were obtained, 

 the first on March 19 and the last on April 10, the females averaging 

 850 eggs each. In addition to the above 50,000 steelhead eggs were 

 received on April 8 in good condition from the Clackamas, Oreg. , Sta- 

 tion, making a total of 161,600. They commenced hatching on April 

 23 and closed on May 6, when 140,000 fry, or 85 per cent, were 

 hatched and distributed shortly afterwards in good condition. 



One of the finest consignments ever received at the Northville Sta- 

 tion arrived from the Bozeman, Mont., Station on May 16, the case 

 containing 209,078 grayling eggs. These were placed in spring water, 

 and in a few days practically all hatched, and shortly afterwards the 

 resultant fry were planted in excellent condition. 



At the Alpena Station hatching operations began on November 20, 

 when 35,000,000 green white-fish eggs were received from the Detroit 

 hatchery, and on December 6 a second shipment of 16,000,000 arrived. 

 From the 51,000,000 eggs thus received 12,500,000 fry, or nearly 81 

 per cent, hatched. The eggs began hatching April 6 and finished 

 April 18. The distribution of the fry was commenced April 11 and 

 was completed April 22, all of the plants being made in Lake Huron, 

 with the exception of 500,000, which were sent to Turtle Lake. 



In addition to the white-fish eggs sent to the Alpena Station, 3,581,000 

 lake-trout eggs were transferred there from Northville and Manistique 

 at various times in the course of the season, and it became necessary 

 to construct additional hatching-troughs to accommodate them. In 

 the month of April 2,530,000 lake-trout fry were distributed, most of 

 them being planted in Lake Huron not far from the Alpena Station. 

 At this point during the past fiscal year a greater number of fry, both
