output during the following years has in each case been followed 
in the fifth year either by a decline or by an increase in the yield 
so large as to outnumber (in numbers of fish) the total quantity of 
fry planted in the parent year. If the fourth or sixth year be 
assumed to be the year in which the first effects of artificial culture 
will be apparent, results very similar await the calculator, showing 
that in only four cases out of the twenty-four examined can artifi- 
cial culture upon the widest assumptions claim even a modest 
interest in an increase or decline.

(a) The Ristigouche column of yields is compiled from the returns for the 
counties of Gloucester and Ristigouche, and from those for the Ristigouche 
division in Quebec. Where the divisions made in the later reports do not 
correspond with those of the earlier, a like course has been followed to that 
described in the Gaspe table. Ristigouche district includes salmon caught 
in the Nepissiguit and Jacquet. 
( b ) Pisciculture in the Ristigouche district began in 1875, averaging about 
<600,000 fry per annum. 
(c) Estimated, as no details of distribution for these years are available. 
(d) Or 783,000.
