Rutilus rutilus Female Oocyte development Synchronous ovogenesis Synchronous
Scardinius erythrophthalmus Female Oocyte development Synchronous ovogenesis but in other areas asynchronous ovogenesis Ambiguous
Lepomis gibbosus Female Oocyte development Asynchronous ovogenesis [In general, the ovaries of the females contained three kinds of oocytes] Asynchronous
Rutilus rutilus Egg Oocyte diameter 0.62-1.09 [Vitellogenic egg], but vary between 1.0-2.1 for other areas in Europe but not specified 0.855 mm
Scardinius erythrophthalmus Egg Oocyte diameter 0.54-0.88 [Vitellogenic egg] 0.71 mm
Lepomis gibbosus Egg Oocyte diameter 0.8-1.8 [Vitellogenic egg] 1.3 mm
Rutilus rutilus Female Absolute fecundity 7-19 [log F = - 4.42 + 3.74 log FL, with FL is the fork length in mm], [Vary between 4-50 in different ears in Europe for a standard female of 170 mm in FL] 13.0 thousand eggs
Scardinius erythrophthalmus Female Absolute fecundity 15-54 for this study 34.5 thousand eggs
Lepomis gibbosus Female Absolute fecundity 5-10 [log F=-0.59+2.16logFL, FL is the fork length in mm] 7.5 thousand eggs
Rutilus rutilus Spawning conditions Spawning season May ['May']
Scardinius erythrophthalmus Spawning conditions Spawning season First two weeks of May ['May']
Lepomis gibbosus Spawning conditions Spawning season From mid-May to Mid-August ['August', 'May']
Rutilus rutilus Spawning conditions Spawning release Spawns only one batch of eggs per season Mutliple
Scardinius erythrophthalmus Spawning conditions Spawning release Monospawner fish but in other areas where female shed the eggs over several months Mutliple
Lepomis gibbosus Spawning conditions Spawning release Multiple spawner fish, each female spawns repeatedly over several months [Spawn several batches of eggs, three times or more at intervals of 20-30 days] Mutliple
