XII -REPORT OF OPERATIONS AT THE MICHIGAN STATIONS 

 OF THE U. S. FISH COMMISSION FOR THE YEAR 1886-'8T. 



By Frank N. Clark. 



During the summer of 188G the whiteiish hatchery at Alpena was 

 closed, as usual. At North ville the small force employed at this seasou 

 was engaged chiefly iu work that is current the year round — the care 

 of ponds and stock fish, &c. — devoting such time as could be spared from 

 this work to preparing for the operations of the ensuing season. The 

 hatching boxes, trays, tanks, &c. ? were repaired or renewed, and coated 

 with asphaltic varnish. It was necessary also to refill with flannel trays 

 the transportation cases that had been emptied by the egg shipments 

 of the previous winter and spring. 



The following table summarizes the receipts and shipments of eggs 

 and fish at both the stations in Michigan :

WHITEFISH. 



The funds available for the collection of whitefish eggs being less than 

 in either of the two preceding years, the field-work was confined to 

 fewer points. Operations in Lake Erie were confined to the fisheries of 

 North Bass, Middle Bass, and Putin-Bay Islands, and the penuiug of 

 fish in Putin-Bay; in Lake Huron to the fisheries along thewest shore 

 from Alpeua to Oscoda, and at Detour and vicinity on the north shore ;
