Artuur.—On the Brown Trout introduced into Otago. 273 
trout in 1869, and finding it measure seven inches, which would represent a 
weight under half a pound. If we say then that the above two trout 
attained a weight in the first year of even one pound, then their subsequent 
average growth must have been 221bs. and $ lbs. respectively, yearly. 
Water of Leith.—In 1869 the first trout were put in this stream, 75 in 
number, and additions have from year to year been made to this and other 
rivers to keep up the stock. In the end of 1874 and beginning of 1875 the 
Leith was opened for angling, when the largest trout caught weighed 8lbs. 
In August, 1875, among a number of spawning fish taken, I saw one 
which must have weighed 7lbs. Mr. Deans, the curator of our Acclimatiza- 
tion Society, informs me of a male trout taken in the Leith, in 1877, which 
weighed 121lbs.; and in February of this year a gentleman caught a female, 
while fishing with artificial minnow, which weighed 10lbs. This latter fish 
I saw; it was a very well-shaped specimen and in excellent condition. It 
is certainly astonishing that trouts can attain such weights in so small a 
stream running through a city like Dunedin! The average yearly growth 
of the largest of these trout—viz., the male fish—is a little over 141bs.—on 
the same supposition as I used regarding the Shag River fish—viz., that it 
was one of the fish put in in 1869. Any other theory will, of course, give a 
more rapid growth, but I do not consider it safe to err in that direction. 
Lee Stream.—Trout were, to the number of 98, put into this (which has 
become the favourite angling stream of Otago) in the year 1869. No other 
lot of trout has ever been added, yet these 98 young fish have stocked the 
stream throughout its whole course of some twenty miles from near the 
Lammerlaw mountains to the Taieri River into which it flows. It was open 
for angling in 1875. In October of that year a well-known angler killed 
some very fine fish with fly. The heaviest of these weighed 5lbs.—this is 
equal to a yearly growth of 4 of a 1b., or say 11b. 
Deep Stream.—In 1869 there were 100 young trout turned out in this 
stream. This is the only lot ever put into the Deep Stream, where fish are 
now plentiful. It was opened for angling in 1875, but no fish over 2 to 4lbs. 
was taken till 1876, when one of 8lbs. was caught with grasshopper. This 
gives ljlbs. as the known yearly growth, on an average, of the trout in 
the Deep Stream. 
Upper Tateri.—In 1870 a few dozen young trout were put into this river 
at the Styx, and in 1875 there were 425 more turned in. At the beginning 
of this year it was fished for the first time, when several large trout were 
taken, weighing from 3 to 6lbs., the largest which was caught with the fly 
being 6Ibs. Gozs. in weight. This gives the greatest possible yearly growth 
at 13 ozs., or say 11b. 
Of other streams we have not so much information; but I may mention 
that large trout have been seen in the Kakanui, Waitati, Lovell’s Creek,
