MOSQUITO ERADICATION 

 OTHER FISHES 



Several species of sun-fishes have been mentioned by different 

 writers in connection with anti-mosquito work, but the observa- 

 tions of Hildebrand indicate that they are of doubtful value.

Fig. 128. — Fountain protected by gold-fish. 



Hildebrand 1 considers gold-fish useful in confinement, although 

 probably of but little value in large bodies of water. Fountains 

 stocked with gold-fish and kept fairly clear of debris and vegeta- 

 tion will rarely show any breeding.
