in Asia, unless this changes.

Wild
carp
races
are
important
resources
for
future genetic improvement
programs.
Many
are
threatened by pollution and by
fish and
water transfers. In
the
PRG, studies on carp genetic resources are now underway (Ma et al., 1981; Li
et
al., 198A).
In
Europe, many
common
carp
‘strains'
are
available (Table
3).
Hybrid crosses — for example, Israeli mirror carp X Taiwanese big belly and Dor 70
X local Hong Kong (Sin, 1982) — show marked heterosis.
Further d00umentation of
carp
genetic
resources,
estimation of genetic parameters and breeding programs
are
needed.
For
Chinese
and Indian
major
carpe,
genetic studies, apart from
hybridization attempts, are only just beginning.

live food production (especially rotiEers, Artemia and cladocerans) and commercial
feeds. The transformation of mixed plankton cultures (produced by fertilizers) into
