Kurzbeschreibung
Morphologie | Morphometrie
Afterflossenweichstrahlen: 10 - 11. Differs from all other species of Cottus in France by having only 10-11 1/2 anal-fin rays. Other characters useful in the identification: posterior tip of second dorsal fin reaching rudimentary caudal-fin rays; no transverse bands on pelvic fin; lateral line complete, with 30-33+1 pores; 13 pectoral-fin rays; no prickling on body; length of caudal peduncle 58-71% HL; depth of caudal peduncle 26-32% HL; predorsal length 34-37 % SL; distance from tip of snout to origin of second dorsal fin 54-57% SL; preanal length 54-58% SL; first and second dorsal fins slightly to moderately joined; snout pale; first dorsal fin with very dark base (Ref. 55856).
Inhabits small stream with clear, swift water and stone bottom (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
