236 DOMESTICATED TROUT. 



5. Give them plenty of space. I mean by space the 

 amount of cubic feet of room to each fish in a pond. 

 This, of course, is not synonymous with range. As, 

 for instance, a thousand head of cattle in a pasture 

 would have as much range as ten head, but ten head 

 confined in it alone would have a hundred times the 

 space. Space is something which cannot be afforded 

 by trout growers generally, but it is necessary to the 

 very large and rapid growth of trout. Put one thou- 

 sand trout in a pond twenty feet square, and ten trout 

 in another pond of the same size, and keep both lots 

 on the same food, and you will be astonished to see 

 how much the growth of the smaller lot exceeds that 

 of the larger lot. Much space is not necessary to 

 keep trout alive in and doing well, but it is neverthe- 

 less indispensable to very large growth. 



The suggestions of this chapter are intended more 

 for amateurs and those who wish to experiment on 

 raising very large trout than for those who make a busi- 

 ness of trout raising ; for though the raising of very 

 large trout is a desirable thing always, it is not often 

 consistent with the best economy, — smaller trout and 

 more of them, with perfect security, being a more profit- 

 able end to seek. 



Section V. — Daily Care of the Large Trout. 



The mere daily care of the large trout is ahnost 

 nothing, if the arrangements for keeping them are 

 right to begin with. I know of no domesticated crea- 

 ture which requires so little daily care. With the ex- 

 ception of feeding them once a day, and keeping the
