When Ova are obtained from private ponds or 

 lakes, my experience is that the cost of collection 

 is much above the highest figure brought out 

 above, viz., 9 per gallon. This, with the 1 , 9s. 6d. 

 per gallon, 1 brings the prime cost of eyed Ova to 

 10, 9s. 6d. per gallon, or at 30,000 to the gallon, 

 6s. 6d. approximately. When the risk, cost of 

 packing, freight, and management are considered, 

 I am of opinion that first class Ova will tend to 

 improve in price. The present wholesale price, 

 including delivery, viz., 37, 10s. per 100,000, 

 being exactly 7s. 6d. per thousand. 



I have given those estimates in the above form 

 chiefly in answer to many inquires from members 

 of District Fishery Boards, many of whom it was

 ponds. In salmon districts there generally exist 

 many natural spawning places inaccessible to 

 salmon. The introduction of salmon to these 

 spawning streams can usually be successfully ac- 

 complished by opening the upper waters through
