Monitoring of gains in weight of Caps fed with cereals in the pond of Fishery Chlum u Třeboně
 CEPÁK, Miloš
Pond management in the Czech Republic uses semi-intensive methods to produce market carp in fishing ponds. Natural food complemented with cereals play an important role in this economical and environment-friendly method of fish breeding. The system makes it possible to increase weight gains of carps in comparison with natural production. At this level of production the market carp maintains high quality meat and therefore it is highly valued also on markets abroad. Every year approximately one half of the market carp production is exported from the Czech Republic and the rest is sold in this country. The purpose of my work is to assess the existing technology of additional feeding of market carp in Fishery Chlum u Třeboně, where I have monitored the stock, spring and , losses, individual weights, weight increases, used feed and feed coefficients. I have also cooperated on monitoring of pilot plant tests in the system of Humlenské ponds where the carps were fed with various cereals
