Milicz Ponds and Barycz river
A bit of information
In the 12th century, monks began to
excavate carp ponds - the Milicz Ponds
were created. Waters were funnelled
from the
river
Barycz
.
The more than
100 Milicz Ponds represent the
world's
largest c
ollection
of
artificial
ponds as
the area spreads over 70 k
m²
. The
Barycz plain has a surface of 5,535
k
m²
-
10
times larger than Lake
Constance.
A bit of history
The carp production is based on
traditional farming practices.
Most of the work, for eight
hundreds of years, is hand-made
by skilled fishermen

Brief description of the carp
cultivation
The production cycle of Milicz carp
is 3 years and consists of 5 stages:
1. Spawning
The best specimens are
selected for spawning. It is
carried out in natural ponds.
Spawning takes place in May
and June in shallow water. The
hatching occurs after 3-5 days.
After hatching the larvae
measure is about 5 mm.
2. Summer fry
The caught hatchery is reared in
small shallow warm ponds,
where hatching in 3-6 weeks,
thanks to very good nutritional
conditions, achieves rapid
growth rate, in a short time. It
grows to a weight of about 5-10
grams.
3. Autum
n fry
The next stage of the production
cycle is the
thir
d one, in which
summer fry is moved to bigger
ponds. The fry is caught in autumn
of the same year. Autumn fry has
the weight 50 to 100 grams. The
fry is fed with cereal grains until
the end of September.
4.”Kroczek” ponds
In the autumn the fry is moved to
much larger areas ponds - from several
to several dozen hectares of greater
depths. Next autumn the carps of
250-500 grams are caught . The second
year carp is so-called „kroczek”(in
Polish). It is the second year of
production from spawning.

Next the carp „kroczek” is moved to

reared with other species of fish, not
competing with them in of food. Fish
in commercial ponds are fed with
cereal. The most intensive feeding
occurs
from
June
to
August. In October
after
3
years of breeding begins the
carp harvest

One of main farm problem
From the carp farm point of
view the optimization of
production from stage
2
to 5 is
very important.
One of main questions
:
How much
fry
should be
used
at the
stage
2
to obtain the best results at
the end of stage 5?
We can control the input at the point
3
. We can also slightly control level of
water at ponds and rate of feeding.
Carp as a very good feast meal
Thank you!
And good progress in
the problem solving!
