10 i'I8S CULTURE. 



become the food of the predatory. Now it so happens 

 that some of the grass eaters are our best table fish, as, 

 for example, the white fish in their several varieties. 

 Hence a wise policy is that which seeks to establish in 

 each pond those varieties which are, in the first place, 

 best adapted to the nature of the pond, its depth, temper- 

 ature and food supply ; and which, from their habits of 

 * life, are mutually inter-dependent. 



Thus, for illustration, a lake like Lake Dunmore, con- 

 taining salmon trout and having deep waters, might be 

 also stocked with some of the smaller varieties of white 

 fish. The result would be that the white fish would grow 

 . in such abundance as to yield annually tons of food in 

 their own proper persons, and by reason of affording from 

 their numbers additional food for the trout already exist- 

 ing, the trout, from being scarce, wouM in jtipie>ibecome 

 exceedingly abundant. To put blasfcsfe&BSjrfriki^aOir any

It will be seen from this that the- 'laws necessary for 

 fish culture of one lake are not those best for another, 

 and that in order that the Legislature should be able to 

 legislate intelligently with regard to the choice of fishes 

 to be introduced into various waters, a visit to each lake 

 would be required, as well as a thorough acquaintance 

 with the whole subject of fish culture. Hence it would 

 seem to be advisable to remit this part Of the matter to 

 the discretion of the Commissioners of Fisheries.
