Individual growth and weight condition of the common carp (Cyprinus carpio m. domestica) in the Nové Mlýny Reservoir (preliminary results)

Individual tagging of the carp (C. carpio f. domestica) 2-year stockfish (K2) was initiated in 2001. In total, 10 thousands specimens were so far tagged with the anchor plastic tags and released into the Nové Mlýny Reservoir on the River Dyje in 2001-2005. According to the 36 registered recaptures (in 2004), the carp reached in the third year of life after 11-12 months exposition in the reservoir (D 316-317, mean 345.3), a body mass of 1500-3900 g (mean = 2264.4+-802.6 g) and a total length of 420-530 mm (mean = 464+-33 mm). These values reveal high trophic sources existing in the Nové Mlýny Reservoir being filled in 1988. When compared with similar data from fishponds of the Czech and Slovak Republics, the growth rate observed showed to be similar or even higher

The individual growth of carp (Cyprinus carpio f. domestica) in two different water reservoirs in drainage area of Morava (CR) the first year after stocking

The growth rate of tagged carps has been studied in two different man-made lakes, namely a shallow reservoir Novomlýnská and the deep reservoir Dalešická over one year after stocking of the two-year-old stockfish. Ten thousands of tagged individuals were released into the Novomlýnská reservoir while 4000 ones into the Dalešická reservoir. The body mass of carps found after one year rearing in the Novomlýnská reservoir (TL=46.4 cm, w=2.26 kg) was twice greater than obtained in the Dalešická reservoir (TL=37.0 cm, w=1.08 kg). Significant differences were stated in all followed parameters. The growth rate registered in the carp from Novomlýnská reservoir resembles that existing normally in pond culture whereas growth rate of carps stocked into the Dalešická reservoir was similar as in carps from running waters
