102 Thirti/srvrntli Annua] Meet lug 



I lioped to have considered. There is anotlier g-rou]j of para- 

 site's than those mentioned, and we made ohservations on tliem. 

 '^rhey are reall}' ectoparasites ; they are found on the skin of 

 small trout, and found also on the small salmon during the first 

 year of its life. The Ehine salmon does exactly as young trout 

 does, and in that tiuu' it is infected just as young trout are, and 

 with the very same species of parasites. I think it is curious 

 that large salmon returning to the sea after having spawned, are 

 infected with that same form. They are not very numerous 

 hut from time to time we catch in the mouth of the river salmon 

 returning from the Ehine and going to the sea. Now with your 

 permission I should like to ask Prof. Ward whether he has any 

 information as to the Pacific salmon being thus infected also, 

 and I thank him beforehand for his kindness in giving me that 

 information. 



Prof. Ward : That is a very interesting question. It can be 

 answered easily, Ijut it brings up a larger question. There is no 

 similarity in parasite faima between the Pacific coast salmon and 

 tlie Phine salmon ; and when we compare the Pacific salmon 

 with the Maine salmon we find more similarity between the Pa- 

 cific and Maine salmon than we do between the Maine salmon 

 and the Rhine sahuon. I presume all ichthyologists would put 

 the Maine salmon and the Rhine salmon very close togethei-, but 

 they would not put the Maine salmon and the Pacific salmon 

 very close together. A year ago I had the privilege, through the 

 courtesy of the Bureau of Fisheries, of studying some salmon in 

 Maine, and the parasitic fauna of even the land-locked salmon 

 from Sebago Lake was more similar to the parasitic fauna of the 

 Pacific salmon than to the parasitic fauna of the Rhine or Elb 

 salmon from the other side of the ocean. 



President: A^liile we are on this subject of the salmon, and 

 because of the fact that there may not be another opportunity 

 to bring up the matter again, I should like to call on Mr. Mee- 

 han for a statement of what he hopes to accomplish in the way 

 of acclimatizing the Atlantic salmon in a river so far south as 

 the Delaware. 



Mr. W. E. Meehan : Mr. Chairman, the establishment of 

 the Atlantic salmon in the Delaware river is somewhat a pet
