168 Tiveiity-ninth Annual Meeting 



DISCUSSION ON THE CARE AND FEEDING OF BROOK TROUT. 

 SUGGESTED BY THE TRIP TO THE EAST FREE- 

 TOWN TROUT HATCHERY. 



The President: Yesterday you had a good opportunity to 

 see one of the practical commercial hatcheries, and it seems to 

 me that we fish-culturists can get more practical points from a 

 man who is in the business to make what he can out of it than 

 from any other source. We are fortunate in having identified 

 with us this year more of the commercial fish-culturists than ever 

 before. You did not have an opportunity yesterday to question 

 j\Ir. Hurlbut very much, and it occurred to me that there might 

 be some questions which you would like to ask him. I want to 

 ask two or three questions for information. I want to ask first 

 whether any of the fish-culturists have considered the vegetation 

 v>diich grows in the bottom of our ponds — I don't know the 

 name of it. but it is very common; in many ponds it grows dur- 

 ing the summer and then rises to the top in hot weather. 

 Whether it is objectionable? Whether there is any preventative 

 for it? ' 



]\Ir. Root: Do you mean that green growth? 



The President: That green growth. You can watch it in 

 the summer and see it rise up, making a tunnel shaped appear- 

 ance like a water-spout, and gradually cut itself of¥ from the bot- 

 tom and float on top. 



Mr. Root: I had occasion, Mr. President, to inquire of one 

 of our scientific men in Providence in regard to that very mat- 

 ter; he said that the vegetation would not grow in a depth of 

 water over fourteen feet; it is only in shallow ponds that it will 

 grow. There is no remedy for it. 



The President: Well, there seems to be no one here that 

 can give us a remedy.
