few days immediately following the plantation of 

 three-month-old fry. Numbers weaken through 

 starvation before they know the feeding spoons, 

 but when there is ten days supply of natural 

 food in the pond, no fry weaken through starva- 

 tion, and five boxes of fry will produce the same 

 number of yearlings that, under less favourable 

 circumstances, six boxes would produce. 



APPROPRIATE EMPLOYMENT OF YEARLINGS. 

 Yearlings fit all uses, they travel better than any 

 other size. They bear out Mr. Guy's description 

 of them in the Howietoun Fishery Price List :- 



' Yearlings are, par excellence, the size for general purposes. 

 They are strong enough to find their own food, thus avoiding 

 the principal cause of mortality among fry, namely, starva- 

 tion ; they are easily carried, and stand the journey well ; 

 they accomodate themselves with the greatest facility to new 

 water ; and they thrive so fast in ponds that they will be 

 found a very profitable investment.' 



As a rule, yearlings are better than two-year- 

 olds for rivers ; of course there are rivers 1 where 

 two-year-olds may be preferred, but all two- 

 year-olds are grown in comparatively still water. 

 It would not pay to make a two-year-old pond on 

 the principal of a long narrow ditch, and this is 

 precisely the principal on which the most successful 

 yearling ponds have been constructed. 



Yearling ponds may be varied in shape to suit 



1 E.g., the Thames below Henley.
