30 THE EDIBLE FISHES OF NEW SOUTH WALES. 
Freshwater Catfish (Copidoglanis tandanus). 
This species, which is well and favorably known as an 
edible fish in parts of New South Wales, bears a general 
resemblance to its congener, just mentioned, but is far 
stouter in build, being comparatively short and thick-set. 
As in the Estuary Catfish, the second dorsal and anal fins 
are continuous, forming a long eel-like fringing fin round the 
tail portion. As I have already indicated, this fish is by no 
means despised as a food-fish as is its estuarine relative, and 
perhaps it is necessity which has brought this about. The 
Freshwater Catfish abounds most commonly in the western 
waters of New South Wales (those which ultimately find their 
way into the River Murray), and as the inhabitants of these 
parts have not the choice of species that residents of the 
coastal districts are favored with, they cannot afford to be 
so particular as to appearance—and certainly the Freshwater 
Catfish is a very unlovely beast. 
In some parts of the country this species is known under 
the name of “ Jewfish,’ but this name is only properly 
applied to the fish known as Scie@na antarcttca. 
In addition to occurring in our western waters, the Fresh- 
water Catfish is found in the head waters of a number of our 
northern east-flowing rivers. 
Salmon-Catfish ((Galeichthys thalassinus). 
Two species of Salmon-Catfish are at present known to 
occur in our waters, but the larger form, above-mentioned, 
is the more common. 
This fish is not at present used largely as food. It is 
found in fair abundance in the lower parts of our great 
northern rivers. 
In form the Salmon-Catfishes are very different to the 
{wo species previously mentioned, having a well-developed 
forked tail and an adipose dorsal fin, as in the typical river 
catfishes of America. 
Galeichthys thalassinus is remarkable in that it has the 
habit of hatching out its large eggs within the mouth cavity.
