| Description
| - U samic raka říčního byla provedena řízená inkubace vajíček pomocí teploty vody podle CUKERZICE et al. (1978) a přirozená inkubace vajíček v přírodních podmínkách. Při řízené inkubaci vajíček byla zkrácena délka inkubace a bylo dosaženo dřívějšího líhnutí tzv. rychlených ráčat. Rychlená ráčata se vylíhla o 88 dní dříve než ráčata normálně vylíhnutá pocházející z přirozené inkubace vajíček. O těchto 88 dní měla rychlená ráčata prodloužený odchov v 1. vegetačním období. Při osamostatnění rychlených ráčat byla zjištěna statisticky nižší plodnost samic, které byly drženy v řízených podmínkách (47 ks # 25,0 ks ráčat ve II. vývojovém stádiu na samici) oproti plodnosti samic umístěných při inkubaci vajíček v přirozeném prostředí (90,1 ks # 46,88 ks ráčat ve II. vývojovém stádiu na samici). Po vylíhnutí rychlených a normálně vylíhnutých ráčat byly obě skupiny ráčat odchovávány ve stejných podmínkách. Při jejich odchovu byl sledován růst a přežívání ráčat. Rychlená ráčata vždy dosáhla v daném časovém obdo (cs)
- The incubation of eggs on plepods of 13 female noble crayfish was controlled by means of water temperature after CUKERZIS et al. (1978). Out-door incubation of eggs on pleopods of 15 females was followed out-door at ambient temperature in an earthen storage pond. With controlled incubation of eggs, the duration of incubation period was shortened and earlier hatching resulted in so-called advanced juveniles. They hatched 88 days earlier than those normally hatched during out-door egg incubation. These 88 days prolonged the rearing period of advanced juvenile crayfish in the 1st growing season. When the advanced juvenile crayfish were isolated, there resulted a significantly lower number of stage 2 juveniles per female kept under controlled conditions (47 # 25.0 individuals of stage 2 juveniles per female) compared to those females placed under out-door conditions (90.1 # 46.9 individuals of stage 2 juveniles per female). Two females lost all eggs during controlled egg incubation, while no females lost
