Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά) : 0; Εδρικές άκανθες: 0. Snout short; upper surface entirely spinulose, but centre of pectoral fins more or less bare in adults, underside smooth except for prickly front edges; generally 9-13 thorns in a complete row around inner margin of eye, and a large triangle of thorns on nape or shoulder region; two parallel rows of strong thorns on each side of midline along tail; upper surface ochre to light greyish-brown with a large roundish black eye-spot in middle of each pectoral fin, underside white (Ref. 3167)

Feed on all kinds of bottom animals (Ref. 3167). 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 5.0-7.0 cm long and 3.1-3.9 cm wide (Ref. 41250). Around 70-150 eggs are laid per individual annually (Ref. 41250).

Life cycle and mating behavior Maturities | Αναπαραγωγή | Spawnings | Egg(s) | Fecundities | Προνύμφες

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 7.2 - 16.7, mean 10.5 (based on 1278 cells).

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

Bayesian length-weight: a=0.00245 (0.00211 - 0.00285), b=3.22 (3.18 - 3.26), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 4.2 ±0.3 se; based on diet studies.

Ελαστικότητα (Ref. 120179): Χαμηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού 4,5 - 14 έτη (K=0.11-0.16; tm=8-9; tmax=28; Fec<100).

Prior r = 0.41, 95% CL = 0.27 - 0.61, Based on 1 full stock assessment.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).

Climate Vulnerability (Ref. 125649): Low to moderate vulnerability (35 of 100).

Price category (Ref. 80766): Medium.
