FISH BREEDING PONDS.

These reasons, and the distance from suitable streams, 
made the Council of the Society abandon hatching 
at the gardens. 
The increasing demand from all parts of Southern 
Australia and New Zealand upon Tasmania for ova 
and fish, and its own requirements, necessarily pre- 
vented an annual supply being continued ; and 
therefore it became necessary, if Victorian streams 
were to be stocked, that breeding ponds should be 
established in the colony. 
Mention ma} r appropriately be here made before 
mentioning the ponds, of the success which has 
already been achieved with the supplies referred to. 
Young fish have been plaeed by the Society in the 
Watts’ River and other headwaters of the Yarra ; in 
Riddle’s Creek, and other streams which empty them- 
selves into the Deep Creek and Saltwater River ; in 
the head waters of the Coliban, which flows north- 
wards to the Murray ; in the head waters of the Broken 
River, which take their rise in the north-eastern 
division of the colony ; at Kilmore, in the same divi- 
sion ; in Dario tt’s Creek, in the western division ; in 
waters near Stawell, in the north-western division ; 
and in streams taking their rise in the Dandenong 
Ranges to the south ; and also in the Y an Yean 
Reservoir. 
The above is independent of the distribution by 
local societies, and in speaking of their success special 
mention is to be made of the society at Ballarat, 
which will probably next year distribute ova from its 
ponds. It successfully hatched trout during the 
seasons 1871-2-3. The young fish were distributed 
into more than twenty streams of the western
