Abstract
The photosynthetic activity of cyanobacteria (predominantly Microcystis spp.) after passage through the digestive tract of Nile tilapia (Oreochromis niloticus) and silver carp (Hypophthalmichthys molitrix) was determined by CCD fluorescence imaging, using slow complementary area approach, during a 4-day cultivation of fish faeces in algal ZBB medium. The cyanobacteria colonies exhibited a 92-95% reduction in of activity (P < 0.001) after passage through Nile tilapia, whereas there was a significant (P < 0.01) stimulation of photosynthetic activity after passage through the silver carp gut.
Abstract (in Czech)
Byla studována fotosyntetická aktivita sinic (především rodu Microcystis) po průchodu trávicím traktem ryb - tilapie nilské (Oreochromis niloticus) a tolstolobikem bílým (Hypophthalmichthys molitrix) pomocí metody zobrazení plošné distriguce fluorescence chlorofylu. Zatímco životaschopnost kolonií sinic byla redukována až z 92-95 procent po průchodu trávicím traktem tilapie nilské, životaschpnost kolonií po průchodu traktem tolstolobika byla stimulována.
