If it is possible, the sorting of carps and tenches is done ri^ht at the pond. In 

 trout fisheries, the erection of a lasting, firm standing and strongly flowing sorting 

 arrangement (in the brood house or at a sluice) to which the fished out trout are 

 brouEiht, is advantageous. It is simplest to use through current holding boxes, similar 

 to long-stream apparatus, which can be separated into many compartments by sieves, for 

 separating the size classes. The sorting itself can be done not only by hand, but also 

 by pouring the trout through stacked boxes, vihose bottoms are made of iron rod grates 

 of various widths (see Fig. 55), and which are set in the v/ater. By gentle lifting the 

 fishes which are too small, slide through the grate, Bachmayer's fish-sorting apparatus 

 consists of a similar box, which has aluminum rods on the bottom, and the spacing can be 

 altered. By means of a simple mechanism the spacing can be varied from 5 to 22 millimeters 

 (1/5 to 7/8 inch). 



Furthermore, in similar fashion, exchangeable grates have been set into carp sorting 

 tables. Fishes below a certain thickness should fall through these grates and land in a 

 tub placed beneath. But I cannot rightly imagine how that kind of an arrangement for 

 sorting larger carps or various kinds of fishes would prove good.

 of various sizes. The spacing between the iron rods on 

 the bottom is widest in the top box, and becomes increas- 

 ingly narrov/er toward the bottom. 



For the unloading and dumping out of fishes (carps, tench and trout) the extremely 

 practical sheet metal slides, and sack hoses provided with a metal ring on the end also 

 deserve to be recommended here. The galvanized iron slide is probably the more pro- 

 tective of the two. The sack hose is however more movable and permits the pouring out 

 of barrels on the truck. In modem large scale operations, belt conveyors are used in 

 loading the sorted and weighed carps into the transport wagons (Fig. 56). The filling 

 of transportation appliances v/ith v/ater is best undertaken on the wagon, for which hand 

 and motor pumps give good service. In filling the fishes into barrels, funnels or 

 straw rings should be used in order to prevent everj' injurj' to the fishes. 



The question of the temporary sheltering, of the holding of the pond fishes, is of 

 the greatest importance from the moment the fishes have been caught. If in large scale 

 fishing out, the sorting is to be done at the pond itself, then storing in the immediate 

 vicinity of the pond is almost indispensable. Net cloths fulfill the service of reser- 

 voirs in the simplest way. They are suspended in a through-flowing ditch or also in a 

 pond by means of poles, so that several sections are formed. In several progressive 

 pond fisheries (see Fig. 57), every large carp pond is provided if possible with a sort
