Species | Development state | Trait | Primary Data | Secondary Data |
Morone saxatilis | Female | Maximum GSI value | Mean of 4% in April, for maturing captive females | 4.0 percent |
Morone saxatilis | Male | Onset of spermatogenesis | In October-November, spermatogenesis began in all males in reared conditions | ['October', 'November'] |
Morone saxatilis | Male | Maximum GSI value | Mean of 9.5, up to 10.5 [Mid-April] in reared conditions | 9.5 percent |
Morone saxatilis | Female | Age at sexual maturity | In the mid-Atlantic region, males reach sexual maturity during their second and third year | No data |
Morone saxatilis | Male | Main spermatogenesis activity | GSI increased rapidly from December to April, mainly December to February in reared conditions | ['February', 'April', 'December'] |
Morone saxatilis | Female | Onset of oogenesis | In October and November of the third year, SG-I oocytes became more numerous. By December, 50% of the fish contained two populations of oocytes in captive maturing females | ['October', 'November', 'December'] |
Morone saxatilis | Female | Intensifying oogenesis activity | January and February in maturing captive females | ['February', 'January'] |
Morone saxatilis | Male | Resting period | In June, after the second reproductive season, testes from mature fish strated to regress and spermatozoa were resorbed. In September (the beginning of the third reproductive cycle) only spermatogonia were present in the testes. | No data |
Morone saxatilis | Female | Age at sexual maturity | In the mid-Atlantic region, females mature between 3 to 7 years | 3.0 year |
