Is the Murray a Salmon River f 61 



the San Joaquin river, in a climate much 

 warmer than that of Florida or the Mississippi ; 

 and they might, he thinks, he successfully in- 

 troduced into the Gulf of Mexico, and possibly 

 into the Eio Grande. Seeing that the brown 

 trout has adapted itself so well to tempera- 

 tures so much greater than any it could 

 ever have experienced in England, it is not 

 unreasonable to suppose that the Californian 

 salmon, which has been proved to be so hardy 

 in Yictoria, should have sufficient adaptability 

 to circumstances to enable it to live and 

 thrive in a climate and temperature so nearly 

 similar to that of its native rivers. 



A new danger to which the salmon would 

 be liable in the Murray is the risk of being 

 devoured by the voracious Murray cod {Oligo- 

 rus Macquariensis), but a swift, active, and 

 powerful fish, like the salmon, has little to fear 

 from a comparatively sluggish swimmer such 

 as the Murray cod, and it is even probable 

 that the scale may be turned the other way, 

 and that the salmon might be well able to 

 hold its ground against the native fish of the 

 country.
