222 Thirty-fifth Annual Meeting 
can be used as a standby to take care of fish for a week or two in 
such cases. 
Mr. Marks: Yes. Three years ago we fed one or two pound 
rainbows nothing else than that for three months. 
Mr. F. R. Bassett: What do you know regarding the quality 
of fish when prepared for the table with this animal food com- 
pared with liver fed fish wholly ? 
Mr. Marks: I could not say. Some of these men that use 
mixtures claim that the fish is improved by them. I do not think 
there is any doubt but what the mixtures of wheat middlings with 
any meat food improves the fish. 
Mr. Bassett: Would you consider it as fattening as meat ? 
Mr. Marks: No, I don’t think so. 
Mr. Titcomb: It keeps your fish in better condition for 
spawning to have some of this food given them. 
Mr. Marks: Yes. 
Mr. Clark: I would Ike to ask regarding the race, if you 
don’t think that better results would be obtaimed and double the 
quantity of fry carried, if you had two sections, each half the 
length of the present raceway, and having the same flow of 
water? In other words, double the quantity of water and double 
your fish by having them in two shorter raceways ? 
Mr. Marks: Yes, I think better results would be obtained by 
the method you suggest. 
Mr. Titcomb: You would double the capacity of your race- 
way for the same length? 
Mr. Marks: Yes sir. We find a loss at the lower end larger 
than at the upper end, if the race were shorter with the same 
volume of water, the lower fish ought to be better. 
Mr. Clark: The idea that I have, Mr. President, is that the 
long trough does not carry fish enough. 
Mr. Titcomb: Would you shorten up your intermediate riffle 
compartment also?
