Fish contains a ligh level of proteins, minerals
and vitamins and as such is an ideal contribution
to the balanced diet of man.
Considering the worldwide tendency to deplete
the oceans resources the planned and controlled
fish breeding and farm operation can
constitute a significant factor in the economy of
a country.
Such a fish farm can be operated in two ways
- either with fry or with spawn. The main conditions
are a constant water quality, temperature
and oxygen content, ozonization and a permanent
and careful supervision. |
