XVIII -A STATISTICAL REVIEW OF THE PRODUCTION AND DIS- 

 TRIBUTION TO PUBLIC WATERS OF YOUNG FISH, BY THE 

 UNITED STATES FISH COMMISSION, FROM ITS ORGANIZATION 



IN 1871 TO THE CLOSE OF 1880. 



By CuAS. W. Smiley, 

 [Cliief of the Division of Records, Statistics, aud Publications.] 



The following tables were prepared with a primary view to furnishing 

 the Tenth Census with suitable summaries of the work done by the 

 United States Fish Commission. The data have been obtained from 

 the records of the United States aud State Commissions and by official 

 correspondence, in the name of Prof. Spencer F. Baird, with the j^ersons 

 to whom he ordered eggs or fish to be sent. The tables have been pre- 

 pared with great care and labor. They are as full and accurate as possi- 

 ble under the circumstances, and may be considered as very exact. Much 

 of the clerical work upon these tables, as well as upon the index thereto, 

 which follows, has been performed, under my careful supervision, by Mr. 

 Carl Brandes, Mr. S. S. Alden, and Mr. C. E. Latimer, each of whose 

 honest aud painstaking labor I desire to make public mention of. 



These tables consist of four series, marked A, B, C, D. 



PRODUCTION. 



A. This table gives the stations operated for shad-hatching from 1872 

 to 1880, inclusive. It shows a total of 41 stations operated in the 9 years, 

 with a total production of 102,388,350 shad, of which nearly 44,000,000 

 were released where hatched, and nearly 54,000,000 transported to other 

 waters. 



B. This series of three tables relates to the production of California 

 salmon. The first table shows the disposition made of 50,701,000 sal- 

 mon eggs, 4,000,000 of which were sent abroad, 15,000,000 hatched and 

 returned to the McCIoud River, and 31,000,000 sent overland to the 

 Eastern States. The second table shows the success in hatching these 

 31,000,000 eggs, the data being arranged by years, while the third table 

 shows the same data arranged by States. These show an average loss 

 of 25 per cent. 



DISTRIBUTION. 



C. This series of six tables summarizes by States the distributions of 

 (1) shad, (2) California salmon, (3) Schoodic salmon, (4) Penobscot sal- 

 mon, (5) whitetish, and (0) California trout, during each year from its 

 commencement to 1880, inclusive. 



D. This series of six tables corresponds to the precedings series of six, 

 and gives in detail the items which are sumuuirized there.
