Harrison. — Salmon and Trout Eggs- 199 



If this is found to be workable grenerally, a new and 

 hitherto unconsidered saving can be effected and great 

 natural wastage of seed prevented. One instance select- 

 ed from several of which the writer is aware will illustrate 

 this: 



In Fifteen Mile Creek a tributary to Babine Lake in the 

 northern interior of the Province, there is a limited spawn- 

 ing erea not more than a quarter of a mile in length, yet 

 annually approximately 12,000 to 15,000 parent sockeye 

 gather off the mouth of this stream. When the first fish 

 are ripe they leave the large school and run up to spawn. 

 Succeeding runs enter the creek and in making their rudds, 

 turn up the eggs of the first spawners within a short time 

 after they have been deposited. This continues for several 

 weeks and finally only the eggs of the last run are left to 

 develop, unmolested. The wastage is enormous and be- 

 hind sunken logs or boulders it is possible to scoop up 

 immense quantities of eggs which have been turned out of 

 gravel and killed while in a delicate stage of development 

 by the later running fish. This loss is tremendous and un- 

 doubtedly the eggs destroyed would be sufficient to fill a 

 small hatchery to capacity. 



When a sure method of planting water-hardened eggs is 

 perfected, as the writer is confident it will be, a spawning 

 camp can be located at the mouth of this creek, all eggs 

 taken as the parent fish become ripe and the spawning 

 ground abundantly seeded by this method. The surplus 

 eggs which otherwise would be lost will then be available 

 for transportation to other creeks in the district where the 

 runs are negligible, and planted there by means of the 

 Harrison planting box. What this saving would be, applied 

 to many other streams in this Province, where similar con- 

 ditions exist, the reader can well imagine. 



In conclusion, the writer feels the need of reiterating 

 his statement that the successful development of this work 

 depends to a very great extent on the fish culturist's know- 

 ledge of his district and the various natural conditions that 

 prevail. 



Discussion. 



Vrebweut Leach: This is a very interesting paper, particularly 

 so to those parts of the country where it is found necessary to plant eyed 

 eggs in more or less inaccessible waters. It is also of great importance 

 to those whe find it necessary to plant surplus eggs, and I am sure that 

 « close study of this paper after it is printed will reveal to you methods
