| Species | Development state | Trait | Primary Data | Secondary Data |
| Esox masquinongy | Egg | Egg adhesiveness | Non-adhesive eggs | Non-Adhesive |
| Esox lucius | Egg | Egg size after water-hardening | Mean size of 2.48 for 41-cm female and 2.80 for 101-cm female [When the eggs reached the 'eye' stage, a sample of 50 from each pike was taken and the diameters measured using a binocular microscope] | 2.48 mm |
| Esox lucius | Egg | Egg adhesiveness | Adhesive eggs | Adhesive |
| Esox lucius | Larvae | Initial larval size | Mean of 7.99 for 41-cm female and 8.09 for 101-cm female | 7.99 mm |
| Esox lucius | Female | Relative fecundity | The relative fecundity of pike in the Lindford lakes (17 and 19 eggs per g) is low compared with the 27 eggs per g for windermere | 17.0 thousand eggs/kg |
| Esox lucius | Female | Absolute fecundity | The lowest calue of absolute fecundity was reported as 2300 eggs from a pike 25 cm in length form Lake disna in the Lithuaniana SSR. In the present study a 37-cm pike from St Peter's Lake was found to have only 44+6 eggs. | 2300.0 thousand eggs |
| Esox lucius | Spawning conditions | Spawning period duration | Ripe female pike were caught from 1 April until 4 May 1986, a period of 34 days, and from 30 March until 18 April in 1987, a period of 20 days | 1.0 weeks |
| Esox lucius | Spawning conditions | Spawning temperature | In the present study, ripe pike were first caught at temperatures of 6.3°C in 1986 and 6.9°C in 1987 | 6.3 °C |
| Esox lucius | Spawning conditions | Spawning water type | Shallow wind-sheltered area | No category |
| Esox lucius | Spawning conditions | Spawning substrate | The optimal spawing substratum for nothern pike is a dense mat of short vegetation. The type of vegetaton does not appear to be critical although grasses and sedges appear to be preferred | Phytophils |
