672 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



•six vacant spaces or holes to an inch, so as to prevent injurious aquatic 

 insects from entering. A grate of this kind will allow the young carp to 

 swim through freely ; and this is really an essential condition of their 

 well-being, as immediately on being hatched they seek the open water 

 and spread over the whole pond. 



After a stay of four weeks, the young carp can be transplanted, but 

 it is not absolutely necessary to do this before autumn or the following 

 spring. 



If lakes and rivers are to be directly stocked with young carp, select 

 a quiet shore, with plenty of floating grass and other aquatic plants, if 

 possible on the north side, so it gets the full benefit of the noonday sun. 

 The young fish will then, soon after having been placed in the water, 

 scatter all over the pond, and soon make themselves acquainted with 

 its natural conditions and with the enemies contained in it. 



There is no doubt that it will be of great advantage to permanently 

 stock our lakes and rivers with young carp, especially as carp raised in 

 lakes and rivers have a much finer flavor than pond carp, and as this 

 seems to be the only way to raise those large and beautiful carp, weigh- 

 ing 20 to 50 pounds, which are the beau ideal of a carp. 



Proprietors of lakes, and even those who have rented lakes, should 

 stock their waters with large masses of young carp ; and with regard 

 to public waters the same should be done by associations. 



Embryonized carp-eggs can be bought here at 2 mark = 57.6 cents per 

 1,000, and in quantities exceeding 5,000, at 23.8 cents per 1,000. 



Young carp (7 to 14 days old) are sold at 10 mark = $2.38 per 1,000, 

 in quantities exceeding 10,000 at $1.19 per 1,000 exclusive of packing 

 and freight to the railroad, which, however, is no very great expense. 

 Boxes, vessels, &c, should be immediately returned at the expense of 

 the sender. Orders are taken till May 1, 1880. 



As regards the size which carp should reach in lakes, I take the lib- 

 erty of giving a correct copy of the following letter received by me some 

 years ago : 



Sabrod, September 6, 1877. 



Mr. R. ECKARDT-LtJBBINCHEN: 



Dear Sir : In answer to your favor of the 29th August, asking for 

 information concerning large carp, I send you all the information I 

 possess. 



My father had, from 1830 to 1840, rented the Swan Lake, and although 

 the rent was not very high, the fisheries in this lake did not pay very 

 well, because its bottom is too uneven, and because it contains some 

 very deep places where fishing apparatus cannot reach. At that time, 

 and perhaps even now, the lake contained magnificent carp, bleie or 

 bream (Abramis brama) weighing 10 to 22 pounds, and perch weighing 

 i pound. During the common fishing season no carp at all were caught, 

 but only during the spawning period. In warm, sultry weather the 

 carp came up to the surface and could be caught with great caution.
