Circular No. i. 



Instructions for Transporting and Ptantincr young FisI). 



Brook, brown, rainbow and Loch Leven trout should be planted in small spring rivulets 

 tributary to the larger stream intended to be stocked. From the rivulets they will work down 

 as they grow, into the main stream. 



Lake trout should be planted among boulders or rocks on a shoal in mid-lake, very near 

 to deep water, into which the young trout soon find their way. In the absence of such shoals 

 with rocks to afford hiding places for the young trout, they may be planted on natural spawning 

 beds, when they are known. 



In transporting young trout if they come to the surface of the water in the cans, it is a 

 sign of exhaustion, and the water should be frequently aerated by dipping it from the can in a 

 dipper and let it fall into it again from a considerable height. It is safer to aerate the water 

 placed in the cans at the hatchery than to add fresh water during the journey, the qualities of 

 which are unknown. Should the water in the cans become warm, the temperature should be 

 reduced by the addition of ice broken into small pieces. 



If the water in the cans containing young trout should be warmer or colder than the 

 water in the lake or stream at the time of planting the fish, the temperature should be equalized 

 by mingling the two waters in the can before the fish are turned out, as marked changes in the 

 temperature may kill the young trout. 



Fish cans ordinarily hold about 5,000 trout fry, and not more than three cans of fry should 

 be planted in one year in a stream from six to eight miles long, and the fry should be well 

 distributed throughout the length of the stream (by planting in rivulets as previously stated), as 

 by bunching the plant there is danger of exhausting the food suitable for the young fish. 



Fry or yearling fish should be planted as soon as received and never under any circum- 

 stances kept over night without constant watching and aerating the water. Trout are sent out 

 by the State in the Spring or Fall, as transportation during the hot months is attended with great 

 risk. 



Applicants for fish should so far as possible ascertain the kinds and quality of fish food in 

 the streams they desire to plant.
