may not be permanent, it has very well proved the efficiency 

 of such a system. Three hundred thousand young Chinook 

 salmon were maintained last year from May until the 15th of 

 August, when they were allowed to enter the Shawsheen River, 

 a tributary of the Merrimack. 



If present plans materialize, a similar station will be estab- 

 lished in the course of another year. 



THE ACRE FISH POND. 



There is scarcely a farm which does not possess some natural 

 pond or some swamp in which an inexpensive pond suitable 

 for raising fish could be made. Unfortunately, the possibilities 

 of small ponds for food production have, up to the present 

 time, been little recognized. In Europe the raising of fish in 

 private ponds is a commercial means of increasing food supply, 

 an item worthy of much consideration in these days of the 

 high cost of living. 



An acre fish pond can be constructed with a small outlay of 

 capital, and can be maintained at a slight expense. Thousands 

 of pounds of fish may be annually produced from such sources. 

 Is that not a good business proposition? This Commission is 

 ready at all times to furnish advice and information to any 

 citizen of the Commonwealth who desires to construct a small 

 fish pond. 



INTRODUCTION OF NEW FISH. 



Artificial propagation, and introduction of new species of 

 fish to local waters, has proved a success in many instances. 

 The large and small mouthed black bass, pike perch, brown 

 trout and other fishes have been introduced into the waters of 

 Massachusetts. The brook trout, an inhabitant of the eastern 

 part of the United States and Canada, is now found throughout 

 the Rocky Mountains, as well as in foreign countries, and the 

 successful introduction of the rainbow trout into New Zealand 

 is a well-known fact. Several western fish such' as the cat- 

 fishes and the crappie, an excellent pan fish, might successfully 

 be introduced into Massachusetts waters in suitable locations. 



In Rhode Island and Pennsylvania the experimental work in 

 the propagation of the Ohio bluegill sunfish has already yielded
