| Description
| - The experiments aimed at prey selectivity in three important carp-pond predatory fish species - pike (Esox lucius), zander (Stizostedion lucioperca) and perch (Perca fluviatilis) were performed under experimental laboratory conditions. Prey fish (39-53,24-37 and 37-51 % TL of pike, zander and perch respectively) were submitted to predators originating from a pond culture. No particular selectivity was registered in pike (139 # 3 mm TL) which slightly preferred asp (Aspius aspius) fingerlings over chub(Leuciscus cephalus) and topmouth gudgeon (Pseudorasbora parva). The specific growth rate (SGR) and food conversion ratio (FCR) in pike fed live food were 1.09 # 0.25 %.day-1 and 6.93 # 1.07 g.g-1 respectively. Only chub and roach (Rutilus rutilus) fingerlings were preferred by zander (244 # 13 mm TL) while other prey fish like perch, topmouth gudgeon and asp were avoided. The SGR and FCR values in zander fed live fish under experimental conditions were 1.67 # 0.14 %.day-1 and 3.41 # 0.49 g.g-1 respecti

- Výběrovost kořisti u tří významných dravých druhů kaprových rybníků - štiky obecné (Esox lucius), candáta obecného (Sander lucioperca) a okouna říčního (Perca fluviatilis) byla studována v pokusných laboratorních podmínkách. Potravní ryby (39-53, 24-37 a37-51% TL štiky, candáta a okouna) byly předkládány dravým rybám pocházejícím z rybničního chovu. Žádná významná selektivita nebyla zjištěna u štiky (139 # 3 mm TL), která mírně preferovala plůdek bolena dravého (Aspius aspius) před jelcem tlouštěm (Leuciscus cephalus) a střevličkou východní (Pseudorasbora parva). Specifická rychlost růstu (SGR) a konverze potravy (FCR) štiky krmené živou potravou činila 1,09 # 0,25 %.den-1 resp. 6,93 # 1,07 g.g-1. Pouze plůdek tlouště a plotice obecné (Rutilus rutilus) byl preferován candátem (244 # 13 mm TL), zatímco ostatní rybí kořist, jako okoun, střevlička a bolen, byla odmítána. Hodnoty SGR a FCR u candáta krmeného živou potravou v experimentálních podmínkách činily 1,67 # 0,14 %.den-1 resp. 3,41 # 0,49 g.g-1. (cs)
