806 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [148] 



3 feet, and a muddy bottom. The pond is full of water a portion of the year, but it is 

 stagnant in dry seasons. The temperature of the pond was 82° on a very warm day in 

 August. 



Plaxts and enemies. — The pond contains white pond-lilies and other water-plants, 

 with roots extending and the leaves floating upon the surface of the water. Frogs in- 

 habit it. 



Food. — I gave the carp bread 3 times a week, but now feed them daily. 



Growth. — I have no original carp, but the 4 carp of the second lot remaining average 

 13 inches in length and weigh 15 ounces. I have seen no young yet. 



Difficulties. — The water got so shallow in the summer that the carp came to the 

 surface. 



663. Statement of J. W. & E. Grove, Fredericksburg, Lebanon Co., Pa., July 26, 1883. 



Disposition of carp received. — The 23 carp received in November, 1880, and the 

 20 received in December, 1881, we put in a pond 40 by 100 feet, with a depth of 5 feet, 

 and a muddy bottom. We allow such an amount of spring water to flow into the pond 

 as will equal that consumed by evaporation. The temperature of the water is from 60° 

 to 65°. 



Plants. — Water-cress and several species of potamogeton grow in the pond. 



Enemies. — The pond is inclosed by a tight fence, and is not inhabited by anything 

 that disturbs the carp. 



Food. — I give the carp 1 quart of com and 1 pint of wheat-screenings once a week. 



Growth. — There are only 1 of the original and 6 of the second lot of carp remaining. 

 They seem to grow rapidly. When we received them they were probably only 3 inches 

 long, and in 12 months they measured 12 inches. The original carp is now about 20 

 inches long and weighs from 8 to 9 pounds. The other 6 average from 4 to 5 pounds. 

 They Irave probably not spawned yet. I have seen no young yet. 



Difficulties. — Before we enclosed the pond by a high tight board fence it was in- 

 fested by muskrats and turtles. During the winter the former destroyed all of the 

 original lot but one. In the spring, while drawing oft' the water from the pond, we 

 found a large snapping-turtle, to which we attributed the destruction of the greater part 

 of the second lot. 



We desire more carp, as our pond is now in a good condition. 



664. Statement of Jacob G. Heilman, Jonestown, Lebanon Co., Pa., July 27, 1883. 



Description of carp received. — The 9 carp received on June 3, 1880, I put in a 

 mill-pond covering about 5 acres, with an average depth of about 5 feet and a bottom 

 composed principally of mud. A large stream, at a temperature of 70° in summer, sup- 

 plies the pond with water. 



Plants. — The pond contains water-lily, dock, and a tall, rank grass that grows a seed. 



Enemies. — Suckers, minnows, catfish, eels, and pike inhabit the pond. 



Food. — I give the carp no artificial food, as I consider the supply of natural food suf- 

 ficient. 



Growth. — I have taken 3 of the original carp which measured, respectively, 24, 18, 

 and 14 inches in length. The largest weighed 7} pounds. 



Reproduction. — I cannot estimate the number of young in the pond. 



Miscellaneous. — My dam is the last one on the Little Swatara, a prolific fish stream 

 well adapted to the propagation of carp. I shall do all in my power to give the carp a 

 permanent foothold, whicli, when gained, Avill result in the stocking of the entire stream, 

 running a distance of about 15 miles. 



665. Statement of H. W. Jarrett, Emaus, Leliigh Co., Pa., Sept. 29, 1883. 



Growth. — The carp I received November 29, 1882, have done well. Yesterday I 

 found 3 leather carp 12.j inches long and weighing fi-om l^to 1] pounds each, beautiful 

 in color and in shape. 



666. Statement of D. K. Kern, Shimerfille, Lehigh Co., Pa., 3Iay 25, 1883. 



Disposition of carp received. — I received 9 scale carp in the spring of 1881, and 20 

 mirror carp November 12, 1881. My pond is situated near the source of a fine creek. 



Growth.— November 25, 1882, my carp were IS inches long and weighed 3 pounds. 



Reproduction. — The carp have done very well, and they produced young last sum- 

 mer.
