artificial fertilization, phosphoric products are used (100 kg/
with nitrogen fertilizer (120—150 kg/ha). The products are
batches over weekly periods.
The length of time the fish stay in these ponds depends upon the
ty of the larvae (250—500/m2) and can even last until the end of the
summer.
Usually the fingerlings stay in_the first breeding ponds for a
mum
of 30—40 days or until they reach a size of 2-3 cm. During the last
days of June, the fingerlings are transferred_to the second breeding
where the cycle finishes
.
These ponds have areas ranging from 500 to
In2 and a depth of 80 to 130 cm in order to guarantee the survival of the gold
fish in low winter temperature. Water exchange is quite slow and varies
ween
2 and 10
The length of time the fish stay there depends upon
the density of the fish and the market demand and varies from 2 to
of 15 months, when the fish reach sizes of 12—20 cm.Balanced pelleted
(@ l-l.5 mm) form the basis of-the diet, but improvement of the
phic capacities of the pond is not neglected..The rational techniques
goldfish breeding described above enable the farmer to produce up to
fish/ha/yr.

The real dimensions of this fish production can be seen from the survey

to
collect as much data as possible on Italian goldfish production and
ting at home and abroad from 1960 to 1984 inclusive. The production
and the number of farmers, were examined (Table 1).
