Common names: Chabot du Lez, Lez sculpin
Occurrence: endemic
Salinity: freshwater
Abundance: scarce (very unlikely) | Ref: Billard, R., 1997
Importance: | Ref:
Aquaculture: | Ref:
Regulations: | Ref:
Uses: no uses
Comments: Occurs in a section 3 km upstream of Lez, a small river in the south of France in the area of Montpellier which is fed by sources of karstic origin. Because of its limited distribution, making C. petiti one of the rarest spcies in France and even in Europe, and the risk of competition with C. gobio, C. petiti is regarded as an endangered species (Ref. 30578). Type locality: sources of river Lez. Also Ref. 55856.

Short description Khóa để định loại | Hình thái học | Sinh trắc học

Các tia vây lưng cứng (tổng cộng) : 5 - 7; Các vây lưng mềm (tổng cộng) : 15 - 16; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 11 - 13; Động vật có xương sống: 30. Differs from other species of Cottusin France by the combination of the following characters: in juveniles and adults, prickling on body extending backwards to caudal peduncle; no distinct transverse bands on pelvic; last dorsal-fin ray reaching rudimentary caudal-fin rays; eye diameter 27-31%; interorbital distance 1.9-2.4 times in eye diameter; last anal-fin ray connected to body by a membrane along about 2/3 of its length; depth of caudal peduncle 24-28% HL (Ref. 55856). Caudal fin with 13 to 16 rays (Ref. 40476).

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).
