Teleostei (teleosts) > Eupercaria/misc (Various families in series Eupercaria) > Sparidae (Porgies)
Etymology: Archosargus: Greek, archo = anus + Latin , sargus = sea bream (Ref. 45335).
Eponymy: Louis François de Pourtalès (1824–1880) was a marine biologist born in Switzerland who spent most of his career in the USA. He presented his extensive collections to the Harvard Museum. No etymology is given, but we presume this to be the person intended. (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 23.5 - 24.6, mean 23.7 °C (based on 19 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02089 (0.00983 - 0.04439), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.32 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).
