88 Thirty-Second Annual Meeting 



trout eamt' out right and what character they were, and he can 

 tell us ; and as I understand him he observed no injury whatever. 



Mr. Hubbard: We had a chance to observe the trout after 

 tlu'v hatched, of course. 



Q. Those very same ones ? 



A. Yes, sir, and they were some of the best fry in the hatch • 

 ery. 



Mr. Atkins : That is pretty conclusive. 



Mr. Hubbard : I wanted to find out in this discussion how 

 salmon or green trout eggs would bear transportation with the 

 least loss ; I do not know if it is very important, but it is quite 

 interesting to me as I had not been able to find means to ship 

 green salmon eggs, and I was very much surprised to find when 

 T came here that the trout eggs would bear transportation with 

 less loss than the salmon eggs. 



Dr. Henshall : I made some experiments with grayling egga 

 when I first began the grayling work in Montana, in order to 

 find out the best time for shipping the eggs, and I have shipped 

 green eggs from the sub-station after shaking and washing them 

 well, for grayling eggs require much more washing than trout 

 eggs, or they will adhere^ — and after the eggs had a good washing 

 and a cliance to absorb all the moisture they would, they were 

 ])acked on trays in the usual way, and put in my refrigerator 

 cases and ship])ed to my hatchery with a loss of about 25 per 

 cent. Tlie rest luitched out and made good fry. Those were per- 

 fecth' green eggs, shipped the same day they were taken. I do 

 not know that I am in order, because I did not hear the original 

 ])a|)ci-, bnt you were speaking of salmon eggs and trout eggs, and 

 that is my experience with green grayling eggs. We now ship 

 tlu'm in less than five days after they are taken. 



Mr. Clark : What was the water temperature for that five 

 days ? 



Dr. Henshall: About o2° F; the eye spots will show in six 

 to seven days. l)ut the embryo is very lively in about five days, 

 and lliat is a good time to ship tliem. as tliey do just as well as 

 when the eye spot shows. 



Mr. George F. Dane, Silver T^ake, ]Mass. : My experience 

 witli trout eggs at a teinperaturc of '^2° is that they should not
