CONCLUSION
As one‘
“this“ review, raising “of common carp
polyCulture is
together with plant—feeding fish
ÎI‘jÏÎ
ging ‘to‘ three groups:
Chinese carpe, Major” Indian Carpe and
This occurs because
the
feeding behaviour of these sh is
different from
that—of CorñmOn carp and5 furthermore, these fish
can
utiüze
directly the primary production of water bodies. This type of ‘
poiycuiture is wel} established in Asia, whereas, it is still being de—‘- *‘
veloped in other parts of“the world. Indigenous fish species do not
participate signiCany to the total yield“ of carp ponds in Europe.
At ieafst in Bas—term Europe”, where great state operated carp farms
exist, the production of indigenous fish Species is teñding to decline
because
they do not increase totai yield in‘polycultuve and they_maKe
pond management more
labor consuming and difficult.
