LXXX REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Alpena Station, Michigan (F. N. Clakk, Superintendent). 



This station was closed from July 1 to November 24, on which date 

 30,120,000 white-fish eggs arrived from the auxiliary station at Monroe 

 Piers, Mich.; 500,000 of these were shipped, as soon as the eye-spots 

 appeared, to New Zealand, for the New Zealand Fish Commission. 

 The eggs seemed to develop normallj^ at first, but about the middle of 

 December Mr. Downing reported them to be in poor condition. A 

 consignment of 30,000 was sent to Northville, and Dr. Blackford, who 

 was engaged there in studying the diseases of the brook trout, made a 

 thorough examination of them, pronouncing them to be in good condi- 

 tion. They were placed in spring water, where they developed very 

 rapidly, half of them hatching by January 27. The eggs at Alpena 

 commenced hatching on April 13 and finished on the 28th, yielding

28,000,000 fry, about 79 per cent of the total number of eggs received. 

 These were deposited in Lakes Michigan, Huron, and Superior, and 

 some inland lakes at Iron Mountain, Mich. 



Arrangements were made during the fall to collect pike-perch eggs 

 in Saginaw Bay, and on the 17th of April the foreman, Mr. Downing, 

 began operations, shipping the first eggs to Alpena on April 20. 'I'he 

 results at this point were only fair, owing principally to the fact that 

 the ice remained in the lake so much later than usual that the earlier 

 spawners, which produce the best eggs, had already deposited their 

 eggs. Collections continued until May 3, but the eggs secured were of 

 poor quality. On A])ril 22 and 25 two shipments of eggs, aggregating 

 41,030,000, were received from the Putin-Bay auxiliary station at Mon- 

 roe Piers. They yielded only about 30 per cent of fry, which hatched
