SALMONID^ 



GKEAT BEITAIN AND lEELAND. 



Among the indigenous fislies of tlie British Isles, those belonging to the salmon 

 family are universally admitted to rank second to none in value, whether regarded 

 as food, as affording sport, or interesting objects for study either in their natural 

 conditions of life or subsequent to changes accidentally effected in their habits or 

 purposely caused by fish-culturists. Composed of forms that jsass the whole or a 

 portion of their existence in salt or in fresh water, they are distributed from 

 a high inland elevation (in some countries even the snow-line) through the 

 lakes and other large pieces of water, the rivers, the streams, and the neighbouring 

 seas. Dispersed over such a wide and varied area the different species frequenting 

 the littoral districts, estuaries, or fresh waters, show, as might be anticipated, 

 many local peculiarities in size, form, and colour, generally dependant on the 

 character of the waters they inhabit, the food available for their subsistence, the 

 circumstances of temperature to which they are subject, or to temporary condi- 

 tions in the fishes themselves. 



In searching the litei'ature of the ancients respecting the salmon family, we 

 do not observe that Salmo salar appears to have been known to the Greeks, 

 .^lian* alludes to a spotted fish in Macedonia that in his days was captured by 

 means of an artificial fly, the mode of manufacturing which he detailed. It is not 

 unlikely that he referred to the trout, or possibly the char, while the species he 

 called Tliymalus, found in the Ticino and Adige, is doubtless the grayling, still 

 existent there. The name suggests the thyme-like odour that some persons have 

 observed to be given off by these fish when fresh from the stream. 



If we turn to the Latins we find that Pliny, the elder, in the first century of 

 the Christian era referred to the salmon, f remarking that in Aquitaiuo it was 

 preferred to all the fishes of the sea. In the fourth century, Ausonius, a native of 

 Bordeaux, one of their poets whose writings have descended to our times, descanted 

 in the most favourable terms on this fish. He mentioned it in his poem "Mosella," 

 being a description of the river Moselle, and he observed that it has red flesh, and 

 springs by strokes of its broad tail from the lower into the higher watci-s above it. 

 He alluded to three species, the salar, or our brook trout: — 

 " Pui-pureisque Salar, stellatus tergora guttis," 

 to the salmon in the lines — 



"Nee te punioeo rutilantem visoere, Salmo, 

 Transierim," 



and to the sea-trout, or as some have termed it the salmon-trout — 



" Teque inter species geminas, neutrunique et utrumque. 

 Qui necdum salmo, nee jam salar, ambiquusque 

 Amborum medio Fario interccpte sub revo ? " 



It is clear that Ausonius referred to two distinct species, the brook trout and 



* ^Uan is supposed to have been bom at Coryous, or at Anazarba in Cilicia, and is said to 

 have flourished about a.d. 180. 



t It has been surmised that the term Salmo was derived from " Salmona," a tributary of the 

 Moselle, mentioned by Ausonius, and that salar had its origin from " salire," " to leap."
