DISCUSSION ON THE PAPER OF 

 DR. TARLETON H. BEAN. 



Mr. Cliene}' : The reference to daplinia as fish 

 food in Dr. Bean's translation seems to be in direct 

 contradiction to the experience of the late Mr. Thos. 

 Andrews, of England, and of Mr. Chas. G. Atkins in 

 this conntry, in that Dr. Jousset de Bellesnie condemns 

 the little crustacean and Mr. Andrews and other fish 

 breeders highly approve of it as food for fishes. This 

 is explainable, perhaps, when it is understood that the 

 French fish breeder desires to obtain quick results in 

 rearing fish for market, while Mr. Andrews and Mr. 

 Atkins commend the daphnia for very young fish, to 

 be reared for breeding, and not for the table, and I 

 think the daphnia should not be condemned as fish 

 food simply because it is not food on which to rear fish 

 to half a pound weight in a given time, for undoubt- 

 edly daphnia constitutes a large portion of the food of 

 our young fishes in wild waters. 



Dr. Bean : I ought not to take the floor au}' fur- 

 ther, but I think I ma}' not have made it perfectly 

 clear that I have seen California salmon reared by Dr. 

 Jousset de Bellesme — and I think probabl}^ there are 

 others of our members who have seen them too — in 

 the Trocadero Aquarium, and even as earl}- as July, 

 when our own trout would be at the most three or four 

 inches long, he had fish six inches long, and he raised 

 them in the way he described. It appeared to me that 

 I had never seen handsomer or bigger fish than he 

 had in the Aquarium. 



In that little place, where he has only four pools 

 for all his experiments with salmon, he gets sixty 

 thousand eggs of the California salmon every year, 

 hatches them, and raises thirt}^ thousand fry. The 

 whole place is run at an expense of twent\'-five hun- 

 dred dollars a vear.
