Diagnostic Description ( Anglèis )

fornì da Fishbase

Biology ( Anglèis )

fornì da Fishbase
Found in cold, karstic spring (Ref. 59043). Laboratory experiments, using natural photoperiod and constant temperature of 15-16°C corresponding with those of its habitat, showed that a female could lay eggs several times with less than one month interval. Between 20 to 70 eggs of relatively large size (2.1 mm) are laid (Ref. 30578).

Cottus petiti ( Anglèis )

fornì da wikipedia EN

Cottus petiti, also called the chabot du Lez in French, is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins.[1] It is endemic to France, found only in a small 3 km stretch of the river Lez in Southern France near Montpellier.[1] The natural habitat is fed by karstic springs which may have enabled the isolated survival of the population through geological history. Now the species may be threatened by habitat loss. The males of this species are typically 56 mm in length. This species was confirmed as a separate species from the European bullhead (C. gobio) in 2005 by Jörg Freyhof, Maurice Kottelat and Arne W. Nolte.[2] The specific name honours the zoologist and anatomist Georges Petit (zoologie) of the Muséum national d’Histoire naturelle.[3]

It is part of the Cottus gobio complex, and genetically very close to C. gobio.[1]
