Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Demersal on insular and continental shelves, and occasionally found in coastal embayments (Ref.58048). Ovoviviparous (Ref. 50449). Caught in large quantities as by-catch of bottom trawl and trammel net fisheries. Utilized for its meat, but of limited value due to its very small size (Ref.58048).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Ovoviviparous (Ref. 205), with histotrophy. Gives birth to litters of 1-2 pups; no reproductive synchronicity. Born at 8-10 cm WD (Ref.58048). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 28.1 - 29.1, mean 28.8 °C (based on 326 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00214 (0.00123 - 0.00371), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Preiskategorie (Ref. 80766):   Low.
