Dr. Emmeline Moore: That is a very interesting point; it might 

 have some application in the case of the depletion of small-mouth black 

 bass around Starve Island. I was going to ask a question this morning 

 on that point. 



Dr. Osburn: In relation to the terns? 



Dr. Emmeline Moore: Yes. However, I rise now to ask another 

 question: What foods of small-mouth black bass — crustacean or insect 

 food — do you find most heavily parasitized? 



Dr. Osburn: Species of Cyclops, and Hyalella. 



Dr. Emmeline Moore: You do not find the Daphnias specially 

 heavily parasitized? 



Dr. Osburn: No. 



Dr. Emmeline Moore: Have you found the larvae of the midge to 

 be heavily parasitized with the round worm? I have found them so 

 occasionally. 



Dr. Osburn: Yes, but I have not made any careful studies of the 

 the midge. That is a problem which I hope to take up one of these 

 times. 



Dr. Emmeline Moore: In the course of examination of young 

 small-mouth and large-mouth basses over two successive years, to the 

 number of about fifty each season I found that the fingerling large- 

 mouth black bass were much more cannibalistically inclined than the 

 small-mouth. 



Dr. Osburn: That is quite true, and the fact that they grow much 

 faster and are able to take fish food much earlier than the small-mouth 

 is, I think, an important factor when they are kept with other fishes, 

 such as sun fish, etc. 



Mr. Doze: Do you find that the small-mouth bass is a longer lived 

 species than the large mouth? The reason I ask is this: we have started 

 work with the small-mouth in Kansas, and we find that our average life 

 of the large-mouth is about ten years. We have got that from develop- 

 ment right in the hatchery. 



Dr. Osburn: The small-mouth would run about the same age, I 

 should think. 



Mr. Doze: What remedy would you suggest for the fungus growth 

 on these fish? 



Dr. Osburn: There is nothing that is eflfective. Individual fish 

 can be cured by salt baths and by use of various germicides, but it is 

 impossible to do that in open waters. 



Mr. Doze: Something has been said about closing the season on 

 bass during the spawning period. When the warm weather stage gets 

 well on in August the bass become infected with worms, so that if we 

 pass legislation restricting the fishing in the spring in a large number 

 of slates we are going to cut out the only time that the angler can 

 catch big-mouth bass that are fit to eat. It is a tradition in our state 

 that the bass will not bite when over the eggs, and I would like to know
