Artificial Propagation. 



The artificial propagation of salmon is carried on at a number of hatch- 

 eries, of which fourteen are on a fairly large scale, and the hatching of 

 white and brown trout is not altogether neglected. The hatcheries vary a 

 good deal in structure, from the elaborate modern establishments on the 

 Bann, Boyne, and Foyle, to the somewhat primitive but quite efficient open 

 air hatcheries of Kerry. 



Formerly these hatcheries relied for support entirely upon the enterprise 

 of private individuals, but during the last two spawning seasons the Depart- 

 ment, recognising the public value of the salmon fishery, offered a subsidy 

 in respect of the output of fry. This offer was accepted in a number of 

 mstances, and the output shows a considerable increase. Under a ten 

 years' agreement with the owners the Department has also provided the 

 cost of enlarging and improving several hatcheries.
