XXVT REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Ill addition to tlieejjgs secured froiii tlie sui)i)ly of fish at the station, 

 on April 4 a eoiisiynmeiit of 2,0()(),0()0 eggs, carried in eight -i-poiiiid 

 butter jars wliieh were sealed and i^acked in ice, was received from the 

 (iloucester Station. Three of the jars contained about 779,500 eggs, 

 Aviiich were taken INIarch 24 and in which tlie embryos were well devel- 

 oped. All these were dead on arrival. The remaining jars contained 

 eggs taken on ]\Iarch 30. Of these, only 400,000 were alive, but not- 

 withstanding their having the usual care they soon died. From these 

 facts Mr. INIaxwell concludes that if the eggs had been transferred 

 immediately after being fertilized, instead of being deferred till an 

 advanced stage of development, when they are more tender, better 

 results would have been possible. 



Flatfish. — The propagation of this species was prosecuted during the 

 period from February 2 to Aprill4, the last lot of eggs being obtained 

 March 18. The ])arent fish were secured from a fyke net placed iu 

 Woods IIoll Harbor. From 94 fish were taken 8,527,800 eggs. The 

 largest number of eggs taken from one fish was 384,000. The weight 

 of this fish when secured was 3 pounds, but after stripping If pouuds.
