FISH BREEDING PONDS. 
From Tasmania, and from Ballarat, the Society have 
received frequent supplies of perch, which have been 
distributed in various parts of the colony. 
A pond was constructed at the Society’s Gardens in 
the Royal Park for perch. 
Prussian carp have been introduced by the Society. 
Tench also, and it is said Dace. 
Roach have been introduced and caught in the 
Yarra, while those who prefer beauty to usefulness may 
indulge in a little fly fishing for goldfish in the same 
stream, where they are to be caught from 1 lb. weight 
upwards and downwards. 
In concluding this report, it may be of use to those 
who have occasion to transport young fish, to describe 
an improvement which the Society adopts, on the plan 
suggested by the Tasmanian salmon commissioners 
in their reprint of Frank Buckland’s “ Hints on Fish 
Hatching and Fish Culture.” It is to enclose all but the 
top of the tin in which the fish are carried, in an open 
net of wire, and over that with a tight-fitting canvas, 
such as buckets are made of; the space between the tin 
and the canvas being filled with water. The water in 
which the fish are is thus kept much cooler than it 
otherwise would be, especially in this climate. 
Another improvement is to place a false bottom in 
the tin, concave in shape, so as not to present any 
cievice or corner into which fish may get; to pierce the 
false bottom with minute holes from the upper side, 
and to connect the space between the false and true 
bottom with a valve and piston at the side, to act 
as an air pump, to be worked with the fingers and 
thumb.
