Frequently the box is replaced by nets which are suspended horizontally between two 

 poles and under the (highly placed) outflow pipe. This method is especially recomnended 

 for catching larger carps and trout. For tench, a fishing out at night is always recom- 

 mended, however this advice is practically seldom followed on account of many other 

 disadvantages. 



The second method of taking out the fishes in front of the sluice is only to be 

 recommended for fishing out larger carps and tenches which can endure a brief sojourn in 

 water which becomes thoroughly muddy ft*om swimming movements and the catching procedure. 

 The catching must not be begun until all the fishes have arrived close to the sluice. 

 Fishes remaining back in the upper part of the fish ditch in large ponds are driven 

 down with nets, reed rolls or with movable fences of bound wooden laths. With small 

 ponds, nets are used to get the fishes out of the fish ditches. With extended ponds, 

 the largest volumes of fishes drawn together in spread out fish ditches at the sluice 

 are to be first taken out with meshed gcoop nets. Unnecessary stirring of mud is to be 

 avoided in the final taking out of fishes. The fortification of the ditch borders 

 gives good services in this respect. 



If extended carp brood or even trout brood are fished within the pond, it can be 

 lured to the inflow by addition of fresh water and taken out there. 



The caught fish, if soiled, should first be placed in a container or tub to be 

 "rinsed", and then upon the sorting table, where they are sorted out according to 

 customary commercial sizes. Smaller quantities of carps can, trout must be sorted by 

 hand ■'.vithout the use of a sorting table. The sorting tables are to be covered smoothly 

 with sheet zinc (see Fig. 5-^) for the protection of Ushes against injury. Smoothly 

 filed holes on the bottom allow the water to flow off. A sloping of the bottom on the 

 one narrow side and a rounded hollow in the transverse wall facilitate the dumping of 

 fishes out of the nets. A cutout on the opposite small side serves for shoving out 

 residues of the sorted fishes (Fig, 54.). The smallest numbers of fishes present (and 

 all sick fishes) are separated out. The fishes are thrown into specially designated 

 vats filled with water, which are grouped about the sorting table. The vats can 

 temporarily be so strongly stocked that there are only about 3 liters of water per kilo- 

 gram (2,74 pints per pound) of fish on hand. For a short time an even stronger stocking 

 of the vats is admissible if some artificial oxygen is introduced. The sorted fishes 

 are then counted, and weighed and then placed in fish boxes, earth containers, hiber- 

 nating ponds, in other ponds, etc. In regard to the sorting of carp brood see Chapter 

 IV, 3, 2.
