REPORT OF COMMISSIONER OF FISH AND FISHERIES. 59 



A tish-fultiir.'il stiiticm plauued to meet all the reqiiirenieuts must be very extensive 

 ami complete in all its apitoiutmeuts, aud will involve luiger expemliture tliau would 

 be reiinired for a station devoted exeliisively to tlie production of whitetisli or the 

 salmouida". The hatchery must he commodious, piovidiug- at once for the hatching 

 of 100,000,000 of wbitelish and ior the incubation of 1,000,000 salnum ova. It must 

 also provide trough accommodations for holding 1,000,000 salmon fry for some weeks 

 after they begin feeding. Quarters, ofitices, storage rooms, and shops must be erected ; 

 an extensive system of ponds for rearing the salmon must be constructed, for none 

 would be released in open waters until they were of sufficient size to have coujpara- 

 tive immunity from capture by other fish. 



At the first installation of the station and for several years it would be necess.ary 

 to draw our supplies of whiteiisli ova from our collecting stations on the upper lakes 

 and our salmon ova from Maine. With the iniinovement of the fisheries we should 

 expect to find our eventual source of supply in Ontario waters, aud the location of 

 the station should be with reference to this. Wherever placed it should bo conven- 

 ient to transportation routes, and should control a gravity water supjdy which should 

 be without stint or measure. 



The cost of such a station as I have indicated, complete in all its appointments, 

 would not be less than $20,000, exclusive of cost of site and water franchises, and for 

 its maintenance there would bo re(|uired an a])]a'o|>iiatioii of $0,000 per annum.
