Dyche. — Possibilities of an Acre Pond 73 



were more young of the green sunfish and blue-gills than 

 of any other variety. 



While the channel catfish were being handled in the 

 transfer tanks, they would spit up fish that they had 

 swallowed. Sunfish, blue-gills, crappie, goldfish and giz- 

 zard shad were most common among the ejected fish. 

 They would range in size from one ounce to one-half 

 pound each. The bull-heads spit up the same varieties of 

 fish but, of course, the average size of specimens was 

 smaller. 



About 16,000 young fish were placed in the ponds (as 

 counted). About 27,000 of all ages and sizes were taken 

 out. Estimated weight of fish placed in pond not to ex- 

 ceed 700 lbs. Estimated weight of fish removed from 

 pond was 6,809 pounds. 



The total number of fish that weighed one pound each 

 or over, was 3,801, and their total weight 5,280 lbs. 



Black bass, crappie and catfish made up 3,988 pounds 

 of this weight. If the weight of the blue-gills and green 

 sunfish that were large enough to eat were added to the 

 above, it would amount in all to over 5,000 (5,315) 

 pounds of good table fish. 



The carp, goldfish and gizzard shad weighed over 1,400 

 pounds. 



The amount of food fed to the fish while they were in 

 the pond can be summed up as follows: 



500 lbs. chopped up liver and meat. 



600 lbs. chopped up fish (mostly German carp). 



200 lbs. corn chop. 



50 lbs. KaiEr corn. 



50 lbs. other kinds of food (bread, oatmeal, potatoes, etc.) 



It might be well to note that about five bushels of tad- 

 poles of the bullfrog were thrown into this pond after 

 it had been stocked. Crayfish were common in this and 

 adjacent ponds. 



DISCUSSION 



President: I hope that the Society is properly impressed with this 

 paper. It is an amazing record. I have never heard anything like it 

 and I strongly suspect that Prof. Dyche has put most of us to a 

 standstill in the matter of pond fish culture. Prof. Dyche's experi- 

 ments show that there is an enormous increment and that the fish food 

 supply can be greatly increased by pond culture.
