Associated characteristics

Species Development state Trait Primary Data Secondary Data
Esox lucius Egg Egg adhesiveness Fertilized eggs swell and adhere to plants, which prevents them from sinking down to the bottom Adhesive
Esox lucius Egg Temperature for incubation At 10°C 10.0 °C
Esox lucius Larvae Larvae behaviour Newly hatched larvae attached to plants remain nonmotile for the first few days of life Demersal
Esox lucius Larvae Reaction to light One-week-old freely swimming larvae are positively phototactic and often swim very near the surface, and they may thus become severely exposed to UV-B radiation Photopositive
Esox lucius Spawning conditions Spawning season In Fennoscandia, pike spawns in April-May ['April', 'May']
Esox lucius Spawning conditions Spawning depth Shallow waters (depth < 1 m) 1.0 m
