Description
  • Byla studována přirozená potrava lína obecného (Tinca tinca L.), kapra obecného (Cyprinus carpio L.) a bufala velkoústého (Ictiobus cyprinellus Val.) pro stanovení potravní konkurence mezi nimi při polykulturním odchovu ve dvou hustotách obsádek. Potrava lína obsahovala převážně zooplankton (43,8%), sediment (21,2%). U kapra dominovala složka dna včetně rostlin a detritu (68,8%) nad zooplanktonem (19,1%). U bufala převažoval zooplankton (80,7%). (cs)
  • Natural diets of tench (Tinca tinca L.), carp (Cyprinus carpio L.) and bigmouth buffalo (Ictiobus cyprinellus Val.) were studied to determine food competition among them in polyculture stocks of two different densities. Tench diet consisted mainly of zooplankton (43.8%) and bottom sediments (21.2%). In contrast, carp diet consisted mainly of bottom items including plant debris and detritus (68.8%), which dominated over zooplankton (19.1%). In bigmouth buffalo, most food bulk comprised zooplankton (80.7%). Thus, the resulting food competition (i.e. similarity) was most pronounced between tench and carp (60.8%) and between tench and bigmouth buffalo (47.4%). When comparing growth performance of the three cultured species, the ratios between stocking and harvesting size were: in normal stocking density (392 kg ha 1) 1.72, 3.67 and 2.13, and in doubled stocking density (777 kg ha 1) 1.07, 2.33 and 2.16 in tench, carp and bigmouth buffalo, respectively.
