How to obtain it. 249- 



few years ago would have availed ourselves of such an opportunity 

 had it been possible. 



The natural food of yearlings, as indeed of fry, may be largely 

 augmented by the introduction of various insects in their larval 

 forms, not only as regards those which inhabit the water, but also 

 the soil and its vegetation, and a study of flora and fauna therefore 

 becomes very desirable. This applies not only to rearing or 

 nursery ponds but to streams and lakes, which may often be very 

 materially improved by the introduction and culture of certain 

 forms of life which were formerly non-existent therein. As 

 applied to our natural waters this subject becomes, then, an 

 exceedingly important economic question, which is well worthy of 

 the study and thought which is being given to it. Some of our 

 winged insects simply abound in their earlier stages in certain 

 localities, and under peculiarly favourable conditions. To supply 

 these conditions in contiguity to our fish ponds is a work of great 

 importance, but which has as yet hardly been entered upon. 



Whilst bearing in mind the value of winged food, the more 

 substantial and solid organisms should not be overlooked, such 

 as mollusca and crustaceans. These play a most important part in 

 the development of fine fish, and also tend to the introduction of 

 that delicate pink tinge of flesh which is so much admired, and to 

 a richness of flavour which is unmistakeable. That the food 

 of fishes has much to do with the flavour of their flesh, fish 

 culturists know quite well. It affects them just as much as the 

 flesh of animals is affected by their food, and experience teaches 

 that a variety of it is the best. It is natural that any animal 

 should be benefited by a mixed diet, and that it is the case with 

 the Salmonidoe, especially when they get older, there is no room 

 for doubt. 



Where large quantities of fish are dealt with it is desirable to 

 use a certain quantity of artificial food. In conjunction with a 

 good amount of natural food the artificial supplies are beneficial, . 

 and with due care in its distribution and a good flow of water 

 the fish at this stage should give very little cause for anxiety. The 

 daily routine of feeding them as their meal times come round, 

 clearing the screens, and attending to the water supplies, is the 

 constant work of their attendant, and very interesting work it is to
