ELEVENTH ANNUAL MEETING. 37 
- by law the size of the mesh and some other minor details. This 
some of the States have attempted, and no doubt others will im- 
itate them. It is also greatly in the interest of certain localities 
to prevent the pollution of their waters with sawdust, decayed 
lumber, offal, etc. 
Artificial propagation has already been attempted on a limited 
scale, and the methods pretty well worked out. It is believed 
that if carried on extensively it may become a very powerful 
factor in the remedy desired. 
The PresipENT.—The paper just read by Mr. Smiley is a most 
valuable one, and exhibits the power of statistics. Such in- 
formation, covering such a wide extent of territory in so thor- 
ough a manner, could not well be gathered by private enterprise, 
nor bythe Fish Commission of any State. The United States 
Fishery Commission is doing a grand work if it never does 
anything else than gather reliable statistics of our fisheries, and 
when this field is well worked, as is now being done, we will 
-have what we never had before—a correct knowledge of our 
fishery resources. 
The Secrerary then read the following : 
HATCHING STRIPED BASS, STURGEON AND TROUT. 
BY ‘SETH GREEN. 
Mr. President and gentlemen of the American Fish-Cultural 
Association :—There have been but a few sturgeon and striped 
bass hatched artificially. The reason that there have not been 
more is that it is so difficult to get the mature fish when the — 
spawn is ripe. In many of our waters there is no great difficulty 
experienced in getting both sturgeon and striped bass that are 
quite far advanced or well along toward the time when they are 
ready to cast their spawn, and if a suitable place could be pre- 
pared where the fish could be placedand kept securely for a few 
days until the ova had reached the proper stage of develop- 
ment, there could be millions of them hatched artificially with- 
out a doubt. .
