Moore. — New Species of Parasite in Trout. 97 



a great many tests with different members. We have kept pretty close watch 

 on them as far as the food is concerned. Our main idea is that we can 

 have a certain number of fish up to a certain size as long as they all get 

 sufficient quantities of food. If a practical feeder will take plenty of time 

 in feeding there should be a minimum of trouble. 



Mr. Titcomb: I just want to give one theory on this whole subject of 

 fish diseases where we raise fish intensively. We know that if we do not 

 take care of ourselves and we happen to be carrying some bacteria in our 

 bodies, we may yield in our weakened condition and become ill. Extend 

 this condition and you have an epidemic like the influenza. With the trout 

 there may be a number of factors contributing to the presence of disease. 

 It may be a lack of oxygen, or something in the food. Anyway, the fish 

 become weakened and they yield to the bacteria or rather protozoa in their 

 bodies.
