| Species | Development state | Trait | Primary Data | Secondary Data |
| Esox lucius | Egg | Incubation time | Yolk-sac fry hatched 8-12 days after fertilization at 15°C | 10.0 days |
| Esox lucius | Egg | Temperature for incubation | Incubated at 15°C [but the lake water temperature was ca. 12°C] | 15.0 °C |
| Esox lucius | Egg | Degree-days for incubation | [Yolk-sac fry hatched 8-12 days after fertilization at 15°C] | 10.0 °C * day |
| Esox lucius | Larvae | Larvae behaviour | The fry attached to this substrate using the adhesive organ on the head | Demersal |
| Esox lucius | Larvae | Temperature during larval development | Reared at 12°C | 12.0 °C |
| Esox lucius | Larvae | Sibling intracohort cannibalism | At 28-35 days cannibalism occurred indepedently in all 12 tanks. The mean age at first cannibalism was 32 days (s.d. = 1.5 days) which occurred at a mean length of 30.3 mm (s.d. 4.3 mm) | Present |
| Esox lucius | Larvae | Full yolk-sac resorption | Yolk sacs were largely resorbed at 8 days (at 12°C) | 8.0 °C * day |
| Esox lucius | Larvae | Onset of exogeneous feeding | The fry began to feed at 7 days post-hatching when the yolk sac was almost completely absorbed (at 12°C) | 7.0 °C * day |
| Esox lucius | Spawning conditions | Spawning migration period | Sexually mature nother pike, undergo an early spring spawning migration | ['April', 'May', 'June'] |
| Esox lucius | Spawning conditions | Spawning water type | Shallow lake margins, inflowing streams, ditches and drainage marshes | Stagnant water |
| Esox lucius | Spawning conditions | Spawning release | Eggs are shed in a succession of batches on flooded arable and grassland, or dense mats of aquatic vegetation | Multiple |
