Very abundant in the IMurray and all the rivers flowing into it, 



but not found naturally in aii}^ of the rivers of Victoria flowing 



south. The Acclimatisation Society many years ago introduced it 



for the first time into the Yarra, where it is now established, but 



does not thrive, although its voracity has sensibly diminished 



the numbers of several of the native fishes of that river,
