206 Thirty-fifth Annual Meeting 
collection of statistics, the construction of fishways, termed “‘sal- 
mon ladders” and “fish passes,” and the issuance of fishing 
licenses; and acts as the adviser of the government in fishery 
matters generally, both fresh water and marine. 
There are, however, numerous private fish culutral establish- 
ments, including two devoted to marine fishes. Of parties en- 
gaged in fresh water fish culture we have a list of thirty-three. 
Of these, twenty-nine are found advertising in a few numbers of 
three Englsh journals in 1906; twenty-eight of them state what 
classes of fish they breed or handle, and twenty-five specify the 
species. We find that amongst these advertisers, eighteen men- 
tion the European brown trout (Salmo fario) ; thirteen the Loch 
Leven trout; twenty-one the rainbow trout (Salmon irideus) ; 
three the American brook trout (Salvelinus fontinalis) ; and one 
party the steelhead trout. Of fishes of other families there are 
four offers of perch, two of roach, and one of bream, and from 
other sources we are able to add to this list of coarse fish for 
sale, carp and tench. 
Some of the establishments, we are informed by our corres- 
pondent, also handle the Atlantic salmon (S. salar) and the gray- 
ling (Thymallus vulgaris). The Atlantic salmon would appear 
to be the special object of the work in the River Eden Salmon 
Hatchery at Carisle. 
As stated above, the American brook trout (S. fontinalis) 
and the rainbow trout (S. Jrideus) are among the species regu- 
larly propagated by many fish cultural establishments, but the 
prospect of their becoming acclimated is not regarded as favor- 
able. ‘The brook trout is reported as having almost entirely dis- 
appeared from the open waters where introduced, and the rain- 
bow, though thriving well under certain conditions, is apt to dis- 
appear entirely from waters where it is not strictly enclosed. 
The acclimatizaton of the steelhead (Salmo Gairdnert) has 
also been tried; and an attempt is now being made to introduce 
the Salmo Hucho from Austria. 
In the marine hatcheries the species thus far propagated 
artificially are three species of flat-fishes, the sole (Solea vulgar- 
is); the flounder (Pleuronectes flesus) ; and the plaice (P. plat- 
essa.) ; and among crustacea the European lobster (Homarus 
vulgaris ).
