Etymology: Isogomphodon: iso-, from isos (Gr.), equal; gomphos (Gr.), nail; odon (Gr.), tooth, referring to how teeth are equally fastened, i.e., claviform and straight in both jaws. (See ETYFish); oxyrhynchus: oxys (Gr.), sharp; rhynchus (L.), snout, referring to its elongated, pointed and narrow snout [authorship often attributed to Müller & Henle, who published Valenciennes’ description].

Estimates based on models

Preferred temperature (Ref. 123201): 27 - 27.8, mean 27.5 °C (based on 149 cells).

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

Bayesian length-weight: a=0.00468 (0.00218 - 0.01003), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.5 ±0.80 se; based on food items.

Generation time: 10.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (K=0.11-0.12; tm=5-7; tmax=12; Fec=4).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (74 of 100).

Catégorie de prix (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 25.1 [3.3, 144.5] mg/100g; Iron = 0.725 [0.183, 2.103] mg/100g; Protein = 21.1 [18.8, 23.3] %; Omega3 = 0.16 [0.06, 0.40] g/100g; Selenium = 29.2 [7.9, 91.1] μg/100g; VitaminA = 18.4 [5.8, 57.1] μg/100g; Zinc = 0.728 [0.335, 1.386] mg/100g (wet weight);
