Salmon Culture in Australha. 59: 
“ After we arrived at the ponds and the deposition of the 
ova completed, I could with great confidence say we had 
at least from 40 to 50 per cent of healthy ova; we then 
cleared away the moss, &c., after which we began our most 
tiresome work of picking out all the dead ova, which took 
us something over six days; since then I have been able to 
count out all that have died during each 24 hours. The 
deaths have been numerous, but not so many as might have 
been expected when we take into consideration the age of 
the ova, or how long ago it is since the ova were taken from 
the parent fish—now 122 days. But with all I have every 
confidence that we shall hatch out a great number of young 
salmon this time. 
“ The hatching, of course, has commenced and this morn- 
ing I can count 98 infants and looking well, and before the 
English mail leaves Australia, I have no doubt but that 
there will be upwards of 1,000.” 
This fully proves that the measures which were taken 
as regards the packing of the salmon ova were dictated 
only after many experiments and great anxiety, and the 
successful issue of them can only bea source of congratula- 
tion to all initiators of a fresh inhabitant into a new country, 
more especially to those who are engaged as Messrs. F. 
Buckland, Youl, Wilson in England and Australia, and in 
America by Mr. Stephen H. Ainsworth, whose remarks as 
to feeding we herewith append from a back number of this 
journal :— 
“The most difficult period in growing trout artificially is 
about the time they commence feeding. This period is from 
forty to sixty days after hatching, according to the tem- 
perature of the water, At this time a large proportion of 
them are very weak, and are entirely unable to stand the 
least current, and consequently are carried with the current 
through the whole length of the hatching-box against the 
screen (if one) at the lower end of the box, and are soon 
suffocated and die. To obviate this put a tank 12 ft. square 
at the lower endof the hatching-box, sothat the waterwill run 
into it, with a gentle current, carrying the weak trout with 
it into the tank, where they can rest in still water from 2 
to 3 inches deep. In this way they will soon recover and 
come into the very slight current to look for food, and, as 
they grow stronger, run up the hatching-box again. By 
this arrangement I have decreased the mortality so that I 
lose but a very small per centage compared to what I did 
before.”
