| Esox masquinongy | Larvae | Onset of exogeneous feeding | Require 13.3 days at 15°C for larvae to swim-up | 13.3 °C * day |
| Esox masquinongy | Female | Age at sexual maturity | 5-7 | 6.0 year |
| Esox masquinongy | Female | Length at sexual maturity | On the basis of spring trapnet catches during spawning (1999-2000), female muskellunge captured at 864-965 mm (34-38 inches) were sexually mature | 1999.5 cm |
| Esox masquinongy | Spawning conditions | Spawning migration period | Muskellunge typically have a protracted spawning run in the St Lawrence River from early May to mid-June | ['May', 'June'] |
| Esox masquinongy | Spawning conditions | Homing | Spawning sites fidelity was observed for radiotracked muskellunge through returns to locations over two successive years. Subsequent data on tagging and recapture of trapnetted spawning adults corroborates this finding. Of 33 fish tagged and recaptured during spawning over many years, all were recaptured at the location of original of original tagging | Present |
| Esox masquinongy | Spawning conditions | Spawning period duration | The presence of muskellunge on spawning grounds, based on trapnet captures of over 280 adults (from 1990 to 2003), was observed between 26 April and June 13 | 280.0 weeks |
| Esox masquinongy | Spawning conditions | Spawning temperature | Water temperatures ranged from 7 to 17°C, and spawning peaked at 10-13°C | 11.5 °C |
| Esox masquinongy | Spawning conditions | Spawning water type | The upper river muskellunge spawning distribution is usually restricted to bays and coastal marshes in shallow waters < 1.5 m deep | No category |
