ties. Unfortunately, stations further from the sea are at a 

 disadvantage, because the transportation of sea-fish involves 

 large expense, and because during the warm season, that is, the 

 summer, the fish can only be sent packed in so much ice, that 

 freight charges are too high. But it is impossible to insist too 

 strongly that sea-fish must not be fed out, which are not quite 

 fresh or which betray by their odor the beginning or advance- 

 ment of decomposition. For it may be counted on with cer- 

 tainty that intcsliual inflammations and great loss will follow 

 the use of spoiled sca-lish, and moreover, there is sufficient rea- 

 son to suspect that by the use of any sort of food which is not 

 fresh, the production of sound eggs and milt is made doubtful. 

 Perhaps the frequently noted degeneration of eggs and milt 

 is to be attributed principally to such not quite fresh foods. 

 Thus even feeding with sea-fish has its limitations, as will be 

 seen, and it must moreover be admitted with regret, that for 

 the feeding of brood-fish we have at present no food material 

 which is in all respects satisfactory and unobjectionable. For 

 if fresh and salt-water fish cannot be used, there remain as a 

 resource only either the dry foods, that is, fish-meal, meat-meal 

 and blood-meal, or the slaughter-house wastes, which however, 

 as will be seen later, in the consideration of feeding for market, 

 all have their faults and deficiencies. 



For the feeding of brood-fish snails are occasionally to be 

 considered, that is, vineyard snails, naked snails of all sorts, 

 such as are found in damp woods, and of course, water snails. 

 These are all to be cooked and thrown to the fish without fur- 

 ther preparation. If they have shells, they must first be pulled 

 out, which is easily done after cooking; or they should be 

 pounded up fine, shell and all. 



Frog meat is also good to use as food for brood-fish. All 

 these and similar foods are, however, unfortunately, to be had 

 only occasionally in sufficient quantity, and play no great 

 role practically. 



We see then that foods for brood-fishes are very limited, 

 and mention that many breeders have altogether abandoned 

 the feeding of brood-fish and employ only wild fish for pro- 

 curing eggs and milt. For European brook trout this posi- 

 tion is undoubtedly the right one, and it would be for the rain-
