Specimens were saved for further study. In one hatchery pond stocked 

 with giant crappie that received water direct from the river supply. 

 twenty-seven spawners died during the spring, and many others seemed 

 to he affected. Almost no young crappie were raised in this pond; 

 however, the goldfish did well in the same pond, apparently not being 

 affected with the fungus. A certain amount of sewage may help to 

 produce food for fish, in one way or another, but on the other hand it 

 may encourage the spread of certain diseases. I am afraid of such 

 water for fish culture purposes. 



When this paper on the diseases of fish is published we shall lie 

 anxious to read every word of it. It may help us out in certain lines, 

 because fish diseases are appearing in different places in the state of 

 Kansas, and we are continually receiving letters of inquiry in regard 

 to fish that are dying from one or another described or fancied cause ; 

 and this is one of the things that has worried me as a fish culturist. 

 After a man has spent considerable money building a pond that may 

 contain several acres of water and has stocked it with fish, he gets 

 nervous and excited as soon as the fish begin to die, and immediately 

 calls upon the fish commissioner for help; and the fish commissioner 

 may not be able to help him, not knowing how to treat or control the 

 disease. A fish culturist is supposed to be a fish doctor. 



We are planning to have a building or station costing from $30,000 

 to $50,000 to be used as a laboratory in connection with and on the 

 state hatchery grounds; and people who desire to study fish and 

 subjects connected with the fish culture business will lie welcome to 

 come and work in this laboratory. We hope to be able to furnish every 

 advantage possible to such students. This laboratory will be under 

 the direction and in connection with the State University. We hope 

 to be able to help students who may be willing to come and study the 

 diseases affecting the fresh-water fishes, such as we have in Kansas. 

 and which same diseases are troubling fish culturists all over the 

 country. 



Mr. G. W. N. Brown, Homer, Minn. : Perhaps I have been more 

 fortunate than most of the members present in having met a man who 

 knew all about fish diseases. While in California 1 met the superin- 

 tendent of a state hatchery, who informed me that he had classified 

 364 different, distinctive fish diseases, almost as many as there are days 

 in the year, and had compounded a remedy for each of these diseases. 

 Unfortunately, however, I did not have the time to take a course in 

 piscatorial medical science. (Laughter.) 



Dr. Tarleton H. Bean, Albany, N. Y. : I do not know anything in 

 the course of a long experience in federal and state fish culture that 

 has so much worried me as the one of fish diseases, unless it may be 

 the interjection of politics into fish culture. (Laughter.) I do not 

 know which is worse, for that is a disease also 



Mr. D. B. Fearing, Newport, R. I. It is hard to eradicate fungus 

 of that character, I can tell you. (Laughter.)
