Oysters on the Oregon Coast: Report

The following is a brief synopsis of the work done last summer and is a con- 

 densation of the more technical report mailed to the U. S. Fish Commission at 

 Washington. 



The introduced oysters were found in July to be in excellent condition and 

 spawning. The process of artificial fertilization was agan resorted to, and countless 

 thousands of fertilized eggs and swimming embryos were consigned^to the waters 

 of the bay. This process has been fully described; its value lies in the fact that im- 

 pregnation is assured if eggs are fertilized in the laboratory, and if they are nursed 

 through the early stages there is that much less exposure to conditions occasionally 

 prevailing in the waters of the bay which are unfavorable to their survival. In this 

 connection acknowledgements are due Dr. W. K. Brooks, of Baltimore, whose reports 

 on similiar work have been extremely helpful. This year, convinced that the 

 warmer and less salt water farther up the bay was more suited to the developing 

 spawn, it was for the most part deposited between Oyster City and the so-called 

 "Ship Yard" 2^/4 miles above the present plant. Some spawn was carried above 

 this point. Further, in the vicinity of the Ship Yard we placed in deep water in
