16 ACCLIMATISATION OF THE SALMOXID.E IX TASMANIA. 



found their way into the Plenty." Owing to a rather heavy 

 mortality amongst the sahnou parr in the ponJ, it was deter- 

 mined to liberate in the Kiver Plenty those remaining. 

 The mortality could not be accounted for by Mr, 

 Ramsbottom, who said the fish affected, " when dead, 

 look as bright and as healthy as any I ever caught with the 

 fly and gentle in the Kibble; fine i)lunip fish they are, and I 

 may say I never saw any so large lor their age." The water 

 in tlie Salmon Pond was lowered and from the 19th to '22nd 

 March, 1865, 419 young salmon, 10 months old, measuring 

 from 5 to 6 inches long were liberated in the Plenty, 1-4 parr 

 were retained being immature, and it was afterwards dis- 

 covered that others were unintentionally kept back, as on 30th 

 January, 1866, 33 siuolts wore taken from the pond and 

 liberated in the Plenty, and on 6th August, 1866, 76 smolts 

 were also liberated. 



The result of the Norfolk shipment of salmon ova was 

 528 salmon counted into the Plenty and an estimated number 

 of at least 1,500 by the rush of water when the leak in the 

 pond was being repaired. In January, 1866, 38 trout were 

 liberated in the Plenty, and 133 were retained in the pond, 

 these fish formed the stock from which and their progeny, and 

 the rivers of this colony, Australia, and of New Zealand, 

 have been supplied. It is well to bear in mind, as already 

 stated, that these trout were the first and only imj^ortation 

 of S. fario into Tasmania, and that the very common opinion 

 that there are several species of brown trout in the colony 

 is thus manifestly inaccurate. Any variability existing must 

 arise from local causes connected with the water and food of 

 the rivers in which the fish are found. 



The Salmon Commissioners having strongly urged the 

 Becessity for a further supply of salmon ova, the Government 

 provided the necessary funds, and the task of management 

 again fell to Mr. J, A. Youl who, through the aid of Messrs. 

 Kamsbottom, si-n., "Westell Pamsbottom, P. Allies, and Thos. 

 Johnson, procured the following lots of ova from the 

 rivers Kibljle, Hudder, near Clithcroe, the Itchin, and its 

 tributaries, near Southampton, the Severn, and Teme, near 

 Worcester, and the Tyne, and Tweed.

 There were also obtained 15,000 ova of sea trout {S. 

 ti-utla), and a box of trout ova, S. fario. The ova were packed 

 in 161 boxes, in the same manner as iu the previous shipment
