Srewart,—On the Introduction and Acclimatization of the Salmon. 209 
long as enables them leisurely to reach the sea, where in their natural 
feeding grounds they rapidly attain size, and return to their rivers again as 
se. 
Although par are exceedingly difficult to transport with safety, it has 
been accomplished ; and to considerable distances. But it would be better 
to prepare nursing streams and ponds, even at every river-basin whose 
waters it is intended to stock. It is well known that the salmon do not, as 
arule, return to any stream, but that from which they proceeded to the sea. 
These ponds and streams need be of a very simple design, the requirements 
being, plenty of cool, clear, and well aerated water, with good current over 
basaltic shingle. And of course, protection from floods and the entrance 
of eels. In this manner a colonial scheme ought to be entered into and 
carried out. But the details of the scheme are by no means few, and 
would necessitate careful study. The introduction should not be confined 
to one year, but a second, or even a third lot of ova would be desirable. 
The scheme could be capable of sending to sea each time, through every 
river selected as suitable in the colony, not less than ten thousand smolts, 
and perhaps 200,000 in all each year. And if some doubt attaches to the 
suitability of such rivers as the Waikato and Waipa, none can be expressed 
in regard to the magnificent shingle beds of the rivers of Canterbury and 
Otago, and other Southern Provinces. I can see no reason against these 
grand counterparts of the Tay, Dee, and Spey, becoming waters teeming 
with salmon, descended from progenitors which have not their equals for 
combined size and quality in the world, Salmon of 71 Ibs. and 64 lbs. have 
been taken in the Tay. Fish like these are worthy to be the ancestors of 
future denizens of the Clutha and Waitaki, and let us hope, if only hope, of 
the Waikato also.
