Associated characteristics


Species Development state Trait Primary Data Secondary Data
Cobitis taenia Spawning conditions Mating system All males in the tank followed the female, the female penetrated into dense vegetation, spotted and one male embraced the female. The female started swimming and the circle began again, often with another male embracing the female No category
Cobitis paludica Spawning conditions Mating system All males in the tank followed the female, the female penetrated into dense vegetation, spotted and one male embraced the female. The female started swimming and the circle began again, often with another male embracing the female No category
Cobitis taenia Spawning conditions Spawning substrate Dense vegetation Phytophils
Cobitis paludica Spawning conditions Spawning substrate Dense vegetation Phytophils
Cobitis taenia Female Female sexual dimorphism No Absent
Cobitis paludica Female Female sexual dimorphism A change of coloration is observed only during spawning activity: the female became very intensely pigmented [This spawning coloration. This spawning coloration disappeared within a few hours after spawning activity Absent
Cobitis taenia Male Male sexual dimorphism No Absent
Cobitis paludica Male Male sexual dimorphism A change of coloration is observed only during spawning activity: the male became pale [This spawning coloration. This spawning coloration disappeared within a few hours after spawning activity Absent
Cobitis taenia Egg Egg size after water-hardening Diameter of chorion mean of 2.49 ± 0.24, range 1.49-3.14 2.49 mm
Cobitis paludica Egg Egg size after water-hardening Diameter of the chorion, mean 1.71 ± 0.08, range 1.53-1.86 1.71 mm
Cobitis taenia Larvae Temperature during larval development 21°C [Rearing condition] 21.0 °C
Cobitis taenia Larvae Reaction to light After eye pigmentation, larvae became negatively phototactic. With the beginning of exogeneous feeding, phototaxis changed into a positive reaction. Photophobic
Phoxinus phoxinus Larvae Reaction to light The free-embryos of the gravel spawning Phoxinus are negatively phototactic in the beginning and hide in the interstitial. After the onset of exogeneous feeding, the young fish become positively phototactic and emerge from the substrate Photophobic
Oncorhynchus gorbuscha Larvae Reaction to light The free-embryos of the gravel spawning Oncorhynchus are negatively phototactic in the beginning and hide in the interstitial. After the onset of exogeneous feeding, the young fish become positively phototactic and emerge from the substrate Photophobic
Oncorhynchus keta Larvae Reaction to light The free-embryos of the gravel spawning Oncorhynchus are negatively phototactic in the beginning and hide in the interstitial. After the onset of exogeneous feeding, the young fish become positively phototactic and emerge from the substrate Photophobic
Oncorhynchus kisutch Larvae Reaction to light The free-embryos of the gravel spawning Oncorhynchus are negatively phototactic in the beginning and hide in the interstitial. After the onset of exogeneous feeding, the young fish become positively phototactic and emerge from the substrate Photophobic
Oncorhynchus mykiss Larvae Reaction to light The free-embryos of the gravel spawning Oncorhynchus are negatively phototactic in the beginning and hide in the interstitial. After the onset of exogeneous feeding, the young fish become positively phototactic and emerge from the substrate Photophobic
Oncorhynchus nerka Larvae Reaction to light The free-embryos of the gravel spawning Oncorhynchus are negatively phototactic in the beginning and hide in the interstitial. After the onset of exogeneous feeding, the young fish become positively phototactic and emerge from the substrate Photophobic
Oncorhynchus tshawytscha Larvae Reaction to light The free-embryos of the gravel spawning Oncorhynchus are negatively phototactic in the beginning and hide in the interstitial. After the onset of exogeneous feeding, the young fish become positively phototactic and emerge from the substrate Photophobic
Cobitis taenia Larvae Onset of exogeneous feeding 120 [6 days at 21°C] 120.0 °C * day
Cobitis taenia Larvae Larvae behaviour After the onset of negative phototaxis, the free-embryos will accumulate at the darkest point in the surrounding, i.e. the bottom beneath the centre part of the vegetation Demersal
