Species | Development state | Trait | Primary Data | Secondary Data |
Micropterus salmoides | Female | Onset of oogenesis | The average increase of GSI was extremely weak from November to February | ['January', 'February', 'November'] |
Micropterus salmoides | Female | Intensifying oogenesis activity | March-April for altitude pond sample, and May for plain pond | ['March', 'April', 'May'] |
Micropterus salmoides | Female | Maximum GSI value | For Low Altitude sample, GSI reach 7.34% [In May] and for high altitude sample, 10.08, up to 11.23% [Early July] | 7.34 percent |
Micropterus salmoides | Spawning conditions | Spawning season | June, at this month spawning period of the pain pond females had begun | ['June'] |
Micropterus salmoides | Spawning conditions | Spawning release | The experiment did not allow to check the occurrence of "multiple spanwing". If it does occur, then it did running within a very short period of time, since in early June there were no stage IV occytes observed in the ovary sections; only stage I oocytes, oocytes in the degenerative process or empty oocytes remained. In other studies: eggs occurred of different development stages and spawning was made by small batches, over a more or less long period | Multiple |
