20 EDIBLE FISHES OF NEW SOUTH WALES. 



mines being allowed to find its \\i\j to the lake. That its introduction to 

 the Tarra has not been an unmixed blessing is clear from the following 

 remarks of Prof. McCoy : — " The Cod is now established in the Tarra, but 

 does not thrive, though its voracity has sensibly diminished the numbers of 

 several of the native lishes of that river, particularly the Blackfish (Gadopsis 

 marmoratus) and the Yarra Herring or Australian Grayling {Prototrodes 

 marcena), which have now disappeared from the lower parts of the Tarra 

 altogether." 



This magnificent species attains to a length of nearly five feet, and a 

 weight of upwai'ds of one hundred pounds.
