Species | Development state | Trait | Primary Data | Secondary Data |
Micropterus salmoides | Female | Onset of oogenesis | Gonadal recrudescence for the following spawning period was observed from November through December, as GSI increased significantly | ['November', 'December'] |
Micropterus salmoides | Female | Onset of oogenesis | Initial gonadal growth occurred between January and March-April | ['January', 'February', 'March', 'April'] |
Micropterus salmoides | Female | Maximum GSI value | 4.57 for 15 forage-fed females (March); 6.97 ± 0.52 for 20 pelled-fed female (April and early May) | 6.97 percent |

Micropterus salmoides | Male | Onset of spermatogenesis | A recrudescence of testicular recrudescence was evident from October through December | ['October', 'December'] |
Micropterus salmoides | Male | Main spermatogenesis activity | Initial gonadal growth occurred between January and April | ['January', 'February', 'March', 'April'] |
Micropterus salmoides | Male | Maximum GSI value | 0.87 ± 0,07 (Beginning of April) but also 1,20 for pellet-fed male ( | 0.87 percent |
Micropterus salmoides | Male | Spermatogenesis duration | 6-7 (From October to March-April) | 6.5 months |
Micropterus salmoides | Male | Resting period | < 0,1 (September, sharp decrease in August) | 3.0 months |
Micropterus salmoides | Spawning conditions | Spawning season | Mid-March | ['March'] |
Micropterus salmoides | Spawning conditions | Spawning period duration | 4-14 | 9.0 weeks |
Micropterus salmoides | Spawning conditions | Spawning temperature | 15 (Observation of the first spawning) | 15.0 °C |
Micropterus salmoides | Spawning conditions | Spawning release | Bass spawned intermittently during the spawning season as revealed by (i) the presence of fry over the entire duration of the spawning season, (ii) pattern of GSI : values returned to the regressed level gradually | Fractional |
