CONCLUSIONS
'
-
…
Carp provide in many ways a very suitable basis on which common forms
of
.integrated
aquaculture
may
be
based,
particularly
in
polycultures.
Although there are several means by which integration may be achieved, the
relatively
low
value
of
carp,
and.
the
existence
of
low—cost
traditional
sources
of
supply,
or
of
competitive
suppliers
from
more
geographically
favoured
areas,
appears
to
remove
much.
of
the
incentive
for
developing
:
such
systems widely in W. Europe.
.
This
does
not
however
argue
against
the
potential
of
as
cost
and
environmental
pressures
increase,
so
the
mdre
nutrient
energy—efficient forms of integration are bound to become more
This
is
however
likely
to
be
a
longer—term
development,
and
carp—mture
is
likely
to
change
considerably
if
it
is
to
successfully
integrate
other
activities.
'
In
this
respect
also,
Table

summarises
the
relative
of
temperate, as opposed to tropical, integrated aquaculture.
