| Species | Development state | Trait | Primary Data | Secondary Data |
| Cobitis taenia | Egg | Egg size after water-hardening | 2.5 mm in diameter | 2.5 mm |
| Cobitis taenia | Egg | Incubation time | Data about a very long hatch time are also confusing: instead of some weeks we observed, in natural rearing conditions, fry hatched in two days [Eggs hatch in nature in few weeks, depending upon temperature, while at laboratory temperature (22-25°C) they hatch 42-48 hours after spawning.] | 23.5 days |
| Cobitis taenia | Egg | Temperature for incubation | Eggs hatch in nature in few weeks, depending upon temperature, while at laboratory temperature (22-25°C) they hatch 42-48 hours after spawning. | 23.5 °C |
| Cobitis taenia | Egg | Degree-days for incubation | Eggs hatch in nature in few weeks, depending upon temperature, while at laboratory temperature (22-25°C) they hatch 42-48 hours after spawning. | 23.5 °C * day |
| Cobitis taenia | Male | Male sexual dimorphism | Sexual dimoprhism is clearly marked: females can be 13 cm long, males do not exceed 9 cm. The male pectoral fin is slighter because of the longer and thicker secondary ray. A blade-like osseous appendage stems from the base of the ray : it is Canestrini's organ, also known as lamina circularis | Absent |
| Cobitis taenia | Spawning conditions | Spawning season | In Piedmont (Italy=, the reproductive period spans from April to June | ['April', 'May', 'June'] |
| Cobitis taenia | Spawning conditions | Spawning site preparation | No, eggs are deposited on the bottom | Susbtrate chooser |
| Cobitis taenia | Spawning conditions | Nycthemeral period of oviposition | Reproduction is achieved mainly at dawn but in some cases during the morning or at night [other studies indicated that eggs are mostly deposited and fertilized at dawn] | Day |
| Cobitis taenia | Spawning conditions | Mating system | In pair, one male and one female, described in detailled [Note: wide range of sexual patterns, due to unbalanced protandrous hermaphroditic and gonochoric populations. Futhermore, there are arrhenoid females, like those obersevd in other species, along with intersexual males referred to as gynoid males] | Monogamy |
| Cobitis taenia | Spawning conditions | Spawning release | Despite the eggs not being abundant, spawning can occur until 4-5 times each day and 100-400 eggs are emitted on the whole. Mating is repeated more than once in the reporductive period | Multiple |
| Cobitis taenia | Spawning conditions | Parental care | No parental care is shown | No care |
