158 Modern Fish culture in Fresh and Salt Water. 



trout, and are found in swift, rapid streams at 85 

 Fahr., especially where there is some shade; but in 

 ponds that temperature is dangerous, even with shade 

 and a good current. In its natural condition this trout 

 is usually found in water varying from 38 Fahr. in 

 winter to 70 Fahr. in summer, and in selecting a site 

 for a trout hatchery spring water with a temperature 

 of 42 to 58 is required. The rainbow trout is a su- 

 perior game fish, a vigorous biter and fights bravely 

 for liberty, though in the east it is somewhat inferior 

 to the brook trout in these respects." The above was 

 written by Mr. George A. Seagle, Superintendent U. S. 

 F. C. Station, Wytheville, Va., for "A Manual of Fish- 

 culture," published by the U. S. Fish Commission in 

 its Report for 1897 pages i to 340 and afterward as 

 a separate book. 



When the fish was first brought east all the fishcultur- 

 ists disliked it, myself among them, because its eggs 

 were not readily impregnated, and when one has to 

 pick out 50 to 75 per cent, of eggs he finds it more 

 work than he wants. It spawned in very early spring 

 or late winter, as one chose to regard February and 

 March, and many of the eggs were hard and "glassy ;" 

 these declined to receive the milt, being already full. 

 This condition we now know to be due to the eggs 

 being over-ripe and absorbing water somehow before 

 extrusion, as they will not readily spawn in confine- 

 ment for some unknown reason.
