Associated characteristics

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
