TRANSPORTATION OF GREEN BROOK TROUT AND 

 SALMON EGGS, RELATIVE TO THE CAPACITY OF 

 THE TWO SPECIES OF EGGS TO BEAR TRANS- 

 PORTATION OR ROUGH USAGE.

This paper is written in the hopes of bringing out some dis- 

 cussion upon this subject, and that members of the Association 

 who have had experiences in this line may relate them. 1 do not 

 claim to have made any new discoveries, and know that all of 

 the experiments tried by me have been tested by others. But 1 

 do claim, as far as my observation and experience have gon.', 

 that brook trout eggs will bear transportation in the green stage 

 with less loss than salmon eggs of the same age. What 1 mean 

 b}^ eggs in the green stage is eggs from one or two, to ten or 

 twelve days old. When I was stationed on the Pacific coast, 

 where I was for twenty-five years in connection with the salmon 

 work, field stations for the collection of salmon eggs were oper- 

 ated in connection with the main station, and it would have of- 

 ten been very desirable if the eggs could have btvn transferred 

 from these field stations to the main station while in the green 

 stage, and I, at several times, tried a number of experiments with 

 this object in view. As T remember, I shipped the green eggs of 

 different ages by various methods. Some L packed on cotton 

 flannel trays, others in moss, and others in glass jars of water, 

 and I decided, from these experiments, that the eggs could not 

 be successfully shipped until they were eyed, and they were 

 therefore left at the field stations until such period. 



Tn ISOO T was transferred to Xew Hampshire, where 1 am 

 now slalioncd. and where the work consists principally in the 

 propagation of l)rook trout, thougli otlier species are also han- 

 dled. When 1 took up this work 1 gained the impression that 

 brook trout eggs were more delicate than salmon, and, therefore, 

 more difiicnlt to handle or transport. While in the northern 

 part of Xew Hani]>shire my attention was brought to the method 

 employed for several years l)y the Xew Hami)shire Fish Com- 

 mission in transferring their trout eggs from the field stations,
