Comments: Found in Tyrrhenian basin from Magra to Garigliano drainages. Introduced in Lake Scanno (Pescara drainage), the only locality where it is known to survive. Abundant in Lake Scanno and apparently stable. Also survived some time in Lake Massaciuccoli (Serchio drainage [north of Pisa]) but the present status of this population is still unknown (Ref. 59043). Recorded from Lakes Nemi, Ronciglione, Bracciano, Fogliano and others (Ref. 13696). Disappeared in areas invaded by introduced S. cf. erythrophthalmus (native to northern Italy). This species still survives but at a single locality where it is still threatened by proposed new introductions (Ref. 55977). Threatened due to proposed stocking of Scardinius hesperidicus and other cyprinids (Ref. 59043). Also Ref. 94493. Status of threat: Critically endangered (Ref. 119201).

Europe: Tyrrhenian basin from Magra to Garigliano drainages in Italy. Introduced in Lake Scanno (Pescara drainage, Italy), which is the only locality where it is known to survive. Also survived some time in Lake Massaciuccoli (Serchio drainage [north of Pisa], Italy) but the present status of this population is still unknown.

Short description Morphology | Morphometrics

Distinguished from its congeners in Mediterranean basin by the combination of the following characters: 37-40 scales along lateral line; anal fin with 9-10½ branched rays; 12-14 gill rakers; body depth 31-36% SL; ventral head profile lacking conspicuous angle at articulation of lower jaw; and all fins dark grey (Ref. 59043).

Inhabits lakes and swamps in or near aquatic vegetation. Threatened due to proposed stocking of Scardinius hesperidicus and other cyprinids (Ref. 59043).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00358 - 0.01465), b=3.14 (2.98 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
