88 Thirtieth Annual Meeting 



our suspicious iu the tlireetiou of the spring water. Measures 

 were taken to insure a fuller supply of lake water during the 

 stage following and immediately preceding hatching, and this 

 has been attended with favorable results. 



I earnestly recommend all fish culturists to keep complete 

 records, even to the verge of fussiness, so complete and exact 

 that they can be intelligently referred to after the lapse of many 

 years. Besides manv other uses, they may serve to solve some of 

 the ]iuzzling prol)lems connected with the diseases of fishes. 



DISCUSSIOX OF MR. ATKIXS' PAPER. 



Prof. Marsh : The reference that the writer makes to epi- 

 lepsy in fishes recalls to my miiul an interesting instance of that 

 disease occurring in the Snowy Grouper (epinephelus niveatus) in 

 the aquarium at Washington. These fish had a peculiar attack of 

 what one might term epilepsy. They became frantic and dashed 

 al)Out the aquarium at a tremendous rate. They looked as if 

 they woiild die, and apparently they did die. Their mouths were 

 wide open and gills distended ; but they came to life again ; and 

 every now and then the fish in this aquarium would undergo the 

 same experience, and did for all the time that they were there ; 

 and this was repeated a number of times, and this family of 

 Groupers seems to be subject to such attacks of fits of epilepsy,, 

 and it is interesting to notice it in Mr. Atkins' experience. 



Mr. Clark : Just before the reading of the first paper the 

 attention of the superintendents was called to the importance of 

 this subject. Its discussion has been very interesting to me and 

 has brought out a great deal that is good. 



General Bryant: Dr. Birge, of the State University, is 

 studying with the greatest care and watchfulness all indications 

 of disease that occur in our hatcheries, and I was in hopes that 

 he would be here today — he may be here tomorrow — he is now 

 president of our university and is so loaded down with adminis- 

 trative cares that he is compeHed to be absent today at least. 



Mr. Bower : Mr. Atkins enumerates in his ]5aper thirteen 

 different diseas^es. Jt looks to me as though the trout culturist 

 has a pretty hard row to hoe, and it seems that new diseases are 

 coming up all the time, or at least old diseases under new names^
