 THEIR INTRODVGTIOIV TO ENGLISH VVATER.H.

[From Laud and Water, May 2, 1S85.] 



Thanks to the liberality of the Commission of Fish and Fisheries of 

 the United States, visitors to the Inventions Exhibition at South Ken- 

 sington have the opportunity for a few weeks of watching the hatching 

 out of the ova of various kinds of fish which have been sent across the 

 Atlantic to the council of the jSTational Fish Culture Association, under 

 whose direction the aquarium attached to the exhibition buildings has 

 been for the last two years. ]STot long ago it appeared highly probable 

 that by May 4 the breeding-troughs would be tenantless. The different 

 consignments of eggs which hacLbeen sent from time to time had hatched 

 out so quickly and the fry had grown so rapidly that it was found nec- 

 essary to remove the latter to more suitable quarters for the rearing of 

 the fish. Within the last few weeks, however, fresh consignments of 

 ova have arrived, and for some time to come the troughs will contain a 

 fine collection of eggs, representing fish hitherto unknown in English 

 waters. 



Among the eggs forwarded from time to time by the American Gov- 

 ernment are those of the lake-trout (Salvelinus namaycush), the rain- 

 bow-trout (Salmo irideus), the Atlantic or Penobscot salmon, the land- 

 locked or Schoodic salmon (Salmo salar subsp. sebago), the quinnat 

 salmon, the whitefish (Coregonus clupeiformis), and the brook-trout 

 ( 8a Ivelinns fontinaUs). 



Referring in inverted order to the fish mentioned above, the American 

 brook-trout is the only one of which we have had any experience as to 

 the practicability of introducing it to our home waters; and it must be 

 said that so far little or no success has followed the attempts to acclima- 

 tize this pretty-looking and, I believe, gamy fish. For many years past 

 thousands of fry have been turned in from time to time to various waters, 

 and the result may be said to be comparatively nothing. FontinaUs of 

 good size are, indeed, occasionally taken here and there, but not in 

 sufficient numbers to give evidence that they have really been estab- 

 lished. Mr. J. T. Maun, who for several consecutive years toQk great 

 pains to introduce the fontinaUs into his fishery in Hampshire, tells me 

 the results were most unsatisfactory. So far as he was concerned, he 

 benefited little by the experiment. The fish appeared to have wandered 

 up stream above his water, where some were taken, but not in any great
