Length at first maturity / Taille / Poids / Âge

Maturity: L_m 2.7, range 3 - 2.7 cm
Max length : 5.7 cm TL mâle / non sexé; (Ref. 2850); common length : 4.3 cm TL mâle / non sexé; (Ref. 12193); âge max. reporté: 1.00 années (Ref. 26474)

Inhabits coastal lagoons and brackish bays at mouth of freshwater streams (Ref. 2850). IS subjected to wide variation in salinity (1-28 ppt.) and temperature (9-25°C) both within and among habitat types. The substrate and vegetation can also differ among lagoon, creek and marsh habitats (Ref. 26474). Feeds mainly on crustaceans, dipteran larvae, gastropods, and invertebrate eggs (Ref. 26474). Oviparous (Ref. 56079). Males construct nesting burrows (Ref. 56079).

Oviparous (Ref. 56079). Eggs are brooded in nesting burrows constructed by males (Ref. 56079).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.2 se; based on diet studies.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (tmax=1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Eucyclogobius newberryi (Girard, 1856)
