36 FISHES OF AUSTRALIA. 



Brown Trout (Salmo fario) and the American Brook 



Charr (Sah'elinns fontiualis). Though these have suc- 

 ceeded in adapting themselves to certain of our waters, par- 

 ticularly those of the Snowy River district, on the whole 

 they are rather more suited for generally colder waters, such 

 as those to be found in Tasmania and New Zealand. 



Before leaving this subject, a few words in regard to 

 the introduction of representatives of the Salmonidae to 

 Australian waters may not be amiss. 



The first experiment was made in 1852 by a Mr. Boccius 

 with Salmon ova. The attempt was unsuccessful, and many 

 of the "croakers" of the day said that it was an impossibility 

 and an idle waste of time and money (by the way, there are 

 still a few of these croakers). However, subsequently, a 

 number of other attempts were made ; each one being unsuc- 

 cessful, but each one profiting by the mistakes of the former, 

 until in 1864, when success at last crowned the efforts of 

 the devoted few who had worked so untiringly. All of 

 these experiments were made in connection with Salmon 

 (Salmo salar) ova. Since that time many other kinds have 

 been introduced either into Australia or New Zealand. The 

 name of James A. Youl (afterwards Sir James)* will always 

 be coupled with these early experiments, as he took a very 

 prominent part in connection with them. 



THE ALEPOCEPKALOIDS. 



(Family: AlepocephaUdcp.) 



THIS is a family of deep-sea fishes, somewhat similar in 

 general structure to the Herrings and Salmons. 



One species, known as Alepocephalus niger, has been 

 obtained from our waters at a depth of 1,400 fathoms. This 

 fish has a compressed though not very elongate body, 

 covered with small scales. The snout projects beyond the 

 mouth. As the specific name implies, the fish is black. 



*Sir James Arndell Youl died in England during June, 1904, at the 

 age of 95 years.
