Thomson. — Separation of Eggs 163 



It may be asked if there are not many live eggs re- 

 moved with the dead ones. Only when I handled them 

 near the hatching period when the eggs could not be al- 

 lowed to remain in the solution for the time required for 

 proper separation. In this case I took a sample and found 

 two ounces of live eggs in a total of twenty-five ounces of 

 eggs removed. Even then I saved a vast amount of time 

 and labor by using the salt solution. 



I have experimented a little with the green eggs, but 

 without satisfactory results. 



All the eggs that I had in the hatchery last winter 

 were handled by myself, single-handed, in the eyed stage, 

 and this summer I have handled over 800,000 of the rain- 

 bow and black-spotted trout with equally good results, 

 so I no longer dread the work of picking out the white 

 eggs at the eyeing stage. The salt solution properly used 

 will save a great deal of labor and expense in the oper- 

 ation of a hatchery. There is no reason why we should 

 not progress in practical fish culture as well as in other 

 lines of industry.
