Biology     Glossary (e.g. epibenthic)

Juveniles associate with drifting seaweed. Plankton feeder (Ref. 12114, 12115). Viviparous (Ref. 34817).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Males established territories ranging from 12 to 70 sq. m; initiated courtship when females approached the territories; lateral display, rushing and turning movements were frequently observed during courtship. Mating pair formed about 30 min before copulation; the pair ascended to 1.5-2.0 m above bottom then males suddenly coiled around the body of females to copulate.

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.01288 (0.00989 - 0.01677), b=3.02 (2.96 - 3.08), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level
(Ref. 69278) 		4.0   ±0.67 se; based on food items.
Generation time 4.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (K=0.25).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (38 of 100). 🛈
Price category
(Ref. 80766) 		Medium.
Nutrients
(Ref. 124155) 		Calcium = 53.1 [20.6, 174.2] mg/100g; Iron = 0.62 [0.26, 1.68] mg/100g; Protein = 18.3 [17.0, 19.7] %; Omega3 = 0.645 [0.255, 1.731] g/100g; Selenium = 82.5 [29.3, 254.6] μg/100g; VitaminA = 10.6 [2.9, 40.2] μg/100g; Zinc = 0.447 [0.234, 0.827] mg/100g (wet weight);
