430 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



agreement made by the United States Commissioner with 

 the fishery authorities of Connecticut and Massachusetts be- 

 ing to put half of all the fish hatched into the Connecticut 

 River, one fourth of this number to be sent up the river to 

 a considerable distance. 



The total number of fish hatched at this station was about 

 3,370,000, of which 2,000,000 were turned loose into the 

 Connecticut, the shipments to other rivers amounting to 

 1,370,000, those from the Hudson and Delaware being only 

 625,000. Of the fish sent from the three rivers, 755,000 were 

 placed in the tributaries of the Mississippi, 280,000 in streams 

 that empty directly into the Gulf of Mexico, and 560,000 in 

 rivers (other than the Connecticut) which empty into the 

 Atlantic. The waters of nearly every state east of the 

 Missouri have been benefited by the shipments made dur- 

 ing the season. There can be no question that this large 

 and widespread distribution of fish will have a very impor- 

 tant bearing uj:)on the solution of the problem of stocking 

 the waters of the United States with useful food fishes. It 

 must be borne in mind that the advantage of the artificial 

 hatching of fish over the natural spawning consists not 

 merely in the ability to plant the fish where it is desired to 

 have them, but also in the much greater success of the work. 

 It is generally estimated that not more than one egg in a 

 thousand (if so many) of those naturally spawned produces 

 a young fish able to provide for itself. In artificial hatch- 

 ing, however, of one thousand eggs taken there is a proba- 

 bility that at least nine hundred, or even more, will reach 

 the above - mentioned stage ; so that, instead of counting 

 upon the proceeds of 4,000,000 eggs under ordinary circum- 

 stances, we should have those of 3,600,000,000. Included in 

 the number of eggs collected at Holyoke were 400,000 ship- 

 ped to Germany on the 17th of July, which were placed in 

 a special apparatus for hatching while on the voj^age. We 

 regret, however, to learn that the experiment, like that of 

 last year, was unsuccessful, the eggs perishing before reach- 

 ing their destination.
