Common names: Etrurian goby, Ghiozzo di ruscello
Occurrence: native
Salinity: freshwater
Abundance: occasional (usually not seen) | Ref:
Importance: of no interest | Ref:
Aquaculture: | Ref:
Regulations: | Ref:
Uses: no uses
Comments: Found in rivers of west central Italy (Serchio, Arno, Ombrone and Tiber basins) (Ref. 12215); including Elsa Torrent and Era R., both affluents of Arno R. (Ref. 43646). P. martensii has been introduced to its area. In 1974 a reduction in abundance and occurrence was noted, but new localities have been listed in 1980. The introduction of P. bonelli, a direct competitor will probably cause the extinction of this species (Ref. 45688). Also Ref. 27118, 45688, 92840, 94493.

Descrição breve Chaves de identificação | Morfologia | Morfometria

Vértebras: 29 - 30. Head canals present, including anterior and posterior oculoscapular and preopercular canals; no interorbital papillae; typically D2 I/11-12 (Ref. 12215). This species is distinguished from other gobies in freshwaters of Adriatic basin and western Italy by the following characters: presence of cephalic lateral line canals; branched rays in second dorsal 11-12.5; scales in midlateral series 44-49; completely scaled caudal peduncle (Ref. 59043).

Found only in freshwater, in shallow, well vegetated shores of small to medium-size streams with moderate flow (over pebble beds, Ref. 26100). Spawns from the first time at 1 year; in May to June; females may repeat spawning during this season. Adhesive eggs deposited between stones, shells and aquatic plants and males guard the eggs until hatching. When spawning and defending the nest, males produce sounds (Ref. 59043). Exhibits territoriality during breeding season. Feeds on a wide variety of invertebrates. A short-lived species which is threatened due to habitat destruction and pollution. (Ref. 26100).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.5 ±0.37 se; based on food items.

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (25 of 100).
