Comprimento de primeira maturação / Tamanho / Peso / Idade

Maturity: L_m ?, range 64 - ? cm
Max length : 63.0 cm WD macho/indeterminado; (Ref. 26408)

Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 8.1 cm long and 4.6 cm wide (Ref. 41249). A common by-catch in the coastal and continental shelf bottom-trawl fisheries of the Argentine-Uruguayan Common Fishing Zone; also fished extensively by bottom longline (Ref. 54460).

Estimates based on models

Preferred temperature (Ref. 123201): 7.7 - 16.4, mean 12.1 °C (based on 114 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00243 - 0.00569), b=3.11 (2.98 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).

Categoria de preço (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 11.9 [2.2, 55.5] mg/100g; Iron = 0.261 [0.068, 0.721] mg/100g; Protein = 17 [14, 19] %; Omega3 = 0.824 [0.275, 3.072] g/100g; Selenium = 9.18 [2.90, 28.35] μg/100g; VitaminA = 16 [5, 52] μg/100g; Zinc = 0.476 [0.229, 0.853] mg/100g (wet weight);
