REPORT OF COMMISSIONER OF FISH AND FISHERIES. *39 



we may have liere a new source of supply to tliat stream. It had been 

 the original intention to place these fish in Skeneateles Lake, but for 

 various reasons Otsego Lake was preferred. 



WMtefish ( Corcyonus alius. ) 



Northrille {Midi.) Station. — It not being convenient to undertake spe- 

 cially the gathering and artificial impregnation of the eggs of the white- 

 fish, arrangements were made with Mr. Frank N. Clark, of Northville, 

 Michigan, to secure and bring forward such a number of eggs as might 

 be needed by the Commission to meet the comparatively small number of 

 apj)lications, the most important of these being from California, Nevada, 

 and several foreign countries. Accordiugly, 500,000 eggs were shipped 

 to Mr. B. B. Redding for the California commissioners. The shipment 

 of the eggs was quite successful, a comparatively small percentage failing 

 to develop. The eggs were packed by Mr. Clark between layers of mos- 

 quito netting, and Mr. Eedding reports that where the layer of netting 

 was single the eggs were in good condition, but where they rested on a 

 fold or tiu-n they were generally killed, thus suggesting an important 

 I)recaution under these circiimstances. The young fish thus obtained 

 were for the most part i)laced in Lake Tahoe. 



Desirous of trying the experiment of the introduction of our whitefish, 

 Coregonus albus, into Germany, I instructed Mr. Clark to put up and 

 forward to Mr. Fred. Mather, for shipment to Germany, a package of 

 50,000 eggs. These were started on the 18th of January, 1S78, and on 

 the 21st Mr. Mather acknowledged their receipt at Newark. As no 

 steamer was up for Germany until the 26th of January, Mr. Mather kept 

 the eggs in his cellar at a temperatnre of 46°, a piece of ice being allowed 

 to melt continually on the top of the box. The authorities of the North 

 German Lloyds having, with their usual liberality, agreed to forward 

 these eggs without expense, they were placed by Mr. Mather, on the 2Gth, 

 in charge of the first officer on the Mosel, by whom they were put in a 

 part of the vessel which, unfortunately, proved to be too warm for them, 

 as, on their arrival in Germany, all were found to have perished. 



Through the mediation of the United States Fish Commission, ar- 

 rangements were made between the Government of New Zealand and 

 Mr. Frank N. Clark for a supply direct of embryonized eggs of white- 

 fish. This commission was satisfactorily executed by Mr. Clark, and 

 the eggs duly placed on board the steamer at San Francisco, and reached 

 their destination in good condition. A large percentage was hatched 

 out, and the young placed in antipodal waters. 



The European Marane "Whitefish (Coregonus marcena). 



The value of the Coregonus or whitefish as an article of food and as a 

 subject for artificial propagation is becoming appreciated in Germany, as 

 it is in the United States ; and the German fish culturists are especially 

 active in experiments and suggestions. A favorite species is what is 

 known as Madue Marccne or Coregonus Marwna of (Bloch.) This is found
