Excerpt from Report on Fish Culture, 1877
Sir, - I have the honor to submit herewith the annual report of fish-breeding operations in the Dominion of Canada for the year 1888, together with a general summary of the work carried on at each of the twelve hatcheries under my super-intendency.
Appended will be found the individual reports containing the transactions in detail, as given by the several officers in charge of each local hatchery in the several Provinces. In these are related the methods pursued for procuring the suppiles of parent fish, from which the eggs are obtained to stock the nurseries. In them will also be found remarks relating to subjects connected with the general interests of the fisheries, and fish culture, which no doubt will entitle them to a perusal and consideration.
The several fish-breeding institutions being wide apart in the performance of their work, reaching from the waters of the Atlantic to the Pacific, and located in all the Provinces of the Dominion save one, have such an unlimited water area in which to operate that, it is found very difficult, indeed almost impossible, to supply the demands that are annually made upon your Department by numerous applicants, for young fish of various kinds, to replenish waters that have become almost denuded of the bettor kinds of fish which formerly inhabited them; and in other cases to introduce better species into lakes, rivers and streams, to which they were not originally indigenous.
With the general increase of population, and improvements of all kinds in many parts of the Dominion, which are continually going on, it has been found that the fish, especially of the better descriptions are correspondingly decreasing, until at last it has become a necessity to institute remedial measures to restore them by the enforcement of judicious laws, for the preservation of the reduced supplies which are in some cases yet to be found; and by introducing the most approved methods for recovering this valuable source of food, and wealth to the country, ere it be wholly lost.
This desideratum has in a largo degree been reached by the greater portion of the civilized governments of the world, by adopting the science of artificial fish culture, an industry which thus far wherever introduced, and extensively carried on, has produced most satisfactory results by restoring many waters to their original standard of fish wealth; and replenishing others with the higher orders of fishes by the acclimatisation of young fish reared in public fish-breeding institutions.
