TEMPERATURE OF WATER. 



The temperature of the surface of the water, taken twelve 

 feet from the shore, where the water was four or five feet 

 deep, during the month of August, at 8 A. M. and 5 P. M., ranged 

 from 70 to 91 degrees Fahrenheit, the usual temperature vary- 

 ing somewhere between 80 and 86. The temperature taken 

 at the bottom of the pond was from one to three degrees lower 

 than at the surface, but never as much as four degrees. The 

 temperature of the air for the same month, taken in the shade 

 at 8 A. M. and 5 P. M., ranged from 70 to 95 degrees Fahrenheit, 

 but on a few occasions was over 100 at some intervening time 

 during the day. 



HOW THE FISH WERE FED. 



The fish in this pond when fed were given liver, chopped-up 

 fish, corn chop and some small quantities of other kinds of fish 

 material. They were fed from a platform that was built about 

 fourteen feet from the east shore and near the deepest basin 

 in the pond. A board walk led from this platform to the shore. 

 On the platform there w^as a chopping block, and during the 

 summers of 1911 and 1912 about 500 pounds of liver and 500 

 or 600 pounds of fish, mostly German carp, were chopped 

 up and fed to the fish. When the chopping began, the fish 

 would appear, the bass first, and then the Channel catfish. 

 The bass would take the first food that was thrown on the 

 water. It was necessary to satisfy them before any of the 

 other fish would have a chance to get any food. The Channel 

 catfish would feed next. The Bluegills and Green sunfish 

 would feed around the edge of the general mass of fish, grab- 

 bing and darting away with anything they could get. The 

 bullheads would come last and stay longest, and would take 

 food from the surface of the water. No crappie were ever 

 seen to come near the feeding station. If they fed at all it 

 was so deep under the water that they could not be seen. 

 About 200 pounds of corn chop were thrown in on the feeding 

 grounds and perhaps as much as fifty pounds of kafir corn. 

 The catfish, carp and goldfish took most of this. However, the 

 Bluegills and sunfish took some of it. When bread was thrown 

 in, the goldfish, carp and bullheads and Bluegills would take it. 



REMOVING THE FISH FROM THE POND. 



About the middle of April, 1913, we began to lower the 

 water in this pond. From April 25 to April 30 the fish were 

 removed and placed in other ponds. Most of the fish were 

 used to stock the ponds of the new Hatchery. After the water 

 had been lowered, the large fish were rounded up by the use of 

 seines with meshes one inch square. Minnow seines were used 

 to capture the small fish. The fish were removed from the 

 water to the tubs and transfer tanks by the use of hand nets 

 ranging in size from eight to twenty inches in diameter. A
