of the economic importance attained and of the fisheries prosecuted. To facilitate 
the identification of the fish, especially on their appearance in new localities, illustra- 
tions of the principal species are included. The reports of State fish commissioners 
have been freely quoted, either as general information or to bear out the writer’s 
statements regarding the different species. 
The importance of this subject and the absence of any special paper dealing with 
its various aspects make it proper to give to the matter the detaded notice which it 
receives in the following pages. While the printed references to the subject have 
been numerous, there are many prominent phases which have not been mentioned, 
and the full extent of the industry which has been established as a consequence of 
the acclimatization experiments is unknown even to the people of the States most 
concerned.

considered in the order given:

This paper is based chiefly on inquiries made by the writer in May and June, 
1894, in the course of an inspection of the economic fisheries of the Pacific States. 
Acting under instructions from Hon. Marshall McDonald, the United States Commis- 
sioner of Fish and Fisheries, special attention was given to those fishes and other 
aquatic animals which had been artificially introduced into the waters of this region. 
Much valuable information has also been obtained from Mr. A. B. Alexander, 
fishery expert on the steamer Albatross , who was detailed in 1893 for an investigation 
of this subject, and submitted a report embodying his observations on shad, striped 
bass, and catfish in the vicinity of San Francisco and in the Columbia River. In the 
following chapters Mr. Alexander’s report has been freely quoted. 
Use has also been made of the information on the foregoing fishes contained in 
the reports of Mr. W. A. Wilcox, field agent of the United States Fish Commission,
