| Description
| - Plodnost a roční cyklus vývinu oocytů byly zkoumány u 79 samic ouklejky pruhované Alburnoides bipunctatus z řeky Rudavy. V průběhu třecího období se reprodukční zdroje zdály více soustředěny v jeho první půlce (více žloutkových oocytů v ovariích v porovnání s druhou půlkou třecího období). U samic průměrné SL = 76 mm a hmotnosti těla bez vnitřností = 7,2 g (N = 13) byla průmerná absolutní plodnost 3020 jiker (SD = 923; 2695 žloutkových oocytů, SD = 1054) a průměrná relativní plodnost 430 oocytů/g (SD = 81; 373 žloutkových oocytů , SD = 100). Počet oocytů se mezi pravým a levým ováriem lišil významně u 63,3 % samic s maximálním rozdílem 1405 oocytů. Absence mezery v distribuci mezi nežloutkovými oocyty (přítomnými v ováriu po celý rok) a žloutkovými oocyty a dále žádný nárůst průměrného diametru u žloutkových oocytů směrem ke konci třecího období naznačují, že ouklejka by mohla být druhem s nedeterminovanou plodností.

- A total of 79 females of spirlin Alburnoides bipunctatus from the Rudava stream were examined to obtain data on fecundity and annual oocyte development cycle. Within spawning season the reproduction resources seemed to be allocated in its former half more intensively. For the mean SL=76 mm and eviscerated body weight = 7.2 g, mean absolute fecundity of females in pre-spawning phase (n=13) was 3020 eggs (SD=923; 2695 yolked eggs, SD=1054), and mean relative fecundity 430 eggs/g (SD=81; 373 yolked eggs, SD=100). Number of eggs in the right and the left ovary differed significantly in 63.3 % of females, with a maximum difference of 1405 eggs. Two clues, namely 1) no gap in distribution between immature, unyolked oocytes (present in an ovary throughout the whole year), and yolked (vitellogenic) oocytes, 2) no increase in mean diameter of yolked oocytes towards the end of spawning season, suggest that spirlin is a species with indeterminate fecundity.
