XXV.-STATISTICS OF THE SHAD-HATCHING OPERATIONS CON- 

 DUCTED BY THE UNITED STATES FISH COMMISSION IN 1881. 



By Chas. W. Smiley. 



From the reports of the various persons in charge of shad-hatching 

 stations during the spring of 1881, and from the reports of messengers 

 in charge of shipments, I have prepared a series of six tables to show the 

 operations at each station, and the seventh for a summary exhibi t. From 

 these it will appear that 87,441,000 eggs were obtained and hatched 

 with an average loss of 20 per cent. A comparison with the number of 

 shad hatched in previous years is of interest, and the constant increase 

 gratifying.
