Associated characteristics

Species Development state Trait Primary Data Secondary Data
Gymnocephalus cernua Egg Egg size after water-hardening The egg diameter was measured in the middle of the spawning season: 0.65-0.85 [In lake Peipsi], 0.9-1.1 [In Matsalu Bay], 0.95-1.25 |In Pärnu Bay] 0.75 mm
Gymnocephalus cernua Egg Temperature for incubation The dishes were kept under the same conditions under natural photoperiod at 16°C 16.0 °C
Gymnocephalus cernua Larvae Initial larval size Standard length of larvae of freswater : meanSL range from 2.05 and 2.23 and brackishwater range from 2.32-3.03 2.67 mm
Gymnocephalus cernua Spawning conditions Spawning release In asynchronous spawners like ruffe, egg size in consecutive batches is found to be smaller, which is associated with the diminishing resources of the female Multiple
