Eponymy: Dr Charles Richard ‘Dick’ Robins (1928–2020) was an American systematic ichthyologist whom one etymology honoured as an ‘eelologist’; as well as a colleague, advisor and friend, for his contributions to the knowledge of fishes (including [...] (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 6 - 12.7, mean 7.8 °C (based on 72 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00194 - 0.00745), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.1 ±0.5 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).
