POND CULTURE. 



(;;;i 



Wherever it is practicable the kegs should be laid on the \vaj,'oii 

 crosswise; aud the waves, also followiug- the iiu)tioii of the wa«;oii, will 

 generally move in a circle along the sides of the keg. The fish which 

 follow this motion do, therefore, not come in such violent contact with 

 the sides of the keg as to be hurt. This manner of placing the kegs 

 should, therefore, be adopted in all cases where fish are to be trans- 

 ported a long distance, but may also be recommended for short jour- 

 neys. In transporting carp and tench short distances, e. g., from one 

 ])0ud to the other, on cool spring or autumn days, the following quan- 

 tity of fish may be put in a keg :

On warm days the number should be smaller. In transporting pike, 

 perch-pike, and trout, one-fourth less should be counted. 



If tish are to be transported several days' journeys, they should be 

 prepared for this transportation, L e., they should not be taken direct 

 from the pond, when they are generally covered with mud, but be placed 

 in tanks containing pure water for several days, so that their gills may 

 be thoroughly cleaned from any mud which may adhere to them. Dur- 

 ing that time they should not receive any food, so that they can be 

 placed in the kegs with an empty stomach. The rocking motion will 

 then not cause them to throw up and i)ollute the water, which in that 

 condition is apt to paste the gills together. Prepared in this manner, 

 and if the kegs are not overcrowded, even tender fish can be trans- 

 ported safely a considerable distance. For long journeys a keg holding 

 5 hectoliters of water should never contain more than 100 pounds of 

 fish, and only in very cool weatlier 200 pounds of carp, while of tender 

 fish, such as perch-pike, trout, pike, &c., 70 pounds is the utmost limit. 

 Diflerent kinds of fish, especially fish of prey and other fish, should 

 never be transported in one and the same keg. 



During long journeys the keg should be refilled with fresh water at 

 least every eight hours. Spring or well water will be the best for this 

 purpose. If it is possible, cool days should be selected for transporting 

 fish any considerable distance ; the cooler the weather the better for 

 the fish. If the transportation occupies several daj's, the fish must be 

 taken out of the kegs during the night aud placed in tanks, so that they 

 may enjoy some rest and be prepared for the fatigue of the following- 

 day. K the fish can be transported by water in perforated boxes at- 

 tached to rafts or boats, this is, of course, the safest method. In that 

 case a large number o£ fish may be put in o:ie box. In transporting
