viii PREFACE 



of fish food continues, anglers and others interested 

 will find that their favorite recreation will become 

 utterly worthless to pursue. I contend that the 

 present breeding and planting of game-fishes, both 

 for economic and sporting uses, would be much 

 improved if more feeding and less breeding were 

 done. 



It is my intention to make this a companion 

 volume, or rather, supplementary to my work on 

 Trout Stream Insects and thus to make more 

 complete the much-needed information so neces- 

 sary to the angler's higher enjoyment of the sport. 

 It contains material which has not been given 

 heretofore in angling books. The creatures pic- 

 tured in colors were all painted from living speci- 

 mens captured in various parts of the Temperate 

 Zone, and the descriptions of their habits are from 

 careful personal studies made during many years' 

 intimate acquaintance with them in the waters 

 in which they abide. If only a few of the sugges- 

 tions made here on fish conservation bear fruit, I 

 shall consider my labor well paid; but further 

 than that, I hope to induce many thoughtful men 

 to realize that angling as a fine art can be better 

 enjoyed if the angler has some knowledge of ani- 

 mated nature connected with his sport.
