There seems to be a wide field for investigation in 
regard to this fungus, and it would be advisable for all 
who are engaged in the business to watch closely and 
give opportunities for a thorough study, if any disease of 
the kind threatens the fish under his supervision or 
observation, 
The following discussion took place: 
Mr. Cary—I would like to ask one question in regard 
to the paper: If I heard correctly you allude to German 
carp as being a predacious or destructive fish to other 
fishes ? 
Mr. James—Where they cannot get their own food. 
It is so stated in the report I read some time ago, that 
the German carp would live on its own kind of food— 
which is vegetable food—but rather than die, it will con- 
sume its own kind. 
Mr. Cary—In connection with this, there was an 
article published in Ohio, alluding to this fact, speaking 
very much against German carp as being predacious fish. 
I have had a good deal of experience with the German 
carp in the State of Georgia. We have no evidence 
that they are to any extent. Ifa large number of carp 
were confined in a small space, I suppose they would eat 
one another sooner than perish; but I don’t think unless 
I have sure positive proof of it, that German carp is pre- 
dacious. 
Mr. James—Where they cannot find sufficient vege- 
table food. They are a rapidly growing fish and require 
a great deal of food to make them grow in that way; and 
that is the statement that I got from an article which led 
me to introduce it in the paper. They are not usually a 
voracious fish as such. 
Mr. Marner—lI think the ichthyological portion of 
that paper on the Alaskan salmon is exceedingly good. 
I am glad as an ichthyologist that the subject came up. 
Dr. Bean published something on it I believe.
