Associated characteristics

Species Development state Trait Primary Data Secondary Data
Lepomis gibbosus Female Onset of oogenesis From January to early May, 1972, the gonads of both sex remained small. The ovaries begin to increase in size during late and early June. The GSI of both sex remained low from August through the fall and winter. Therefore it appears that the first sign of recrudescence in both males and females occurred during late May in 1972 ['January', 'February', 'March', 'May', 'June', 'August', 'October', 'November', 'December']
Lepomis gibbosus Female Intensifying oogenesis activity June ['June']
Lepomis gibbosus Female Maximum GSI value Mean of 7, up to 9.5% [In July] 7.0 percent
Lepomis gibbosus Female Resting period From Setember to May 2.0 months
Lepomis gibbosus Male Onset of spermatogenesis It apperas that first sign of gonadal recrudescence occurred during late May ['May']
Lepomis gibbosus Male Main spermatogenesis activity May ['May']
Lepomis gibbosus Male Maximum GSI value Mean 0.9, up to 1.1% [in June] 0.9 percent
Lepomis gibbosus Male Resting period October to May 8.0 months
