Etymology: Mustelus: Latin for weasel, an ancient name for sharks, possibly referring to the pointed snouts, swift movements and/or rapacious feeding behavior of smaller predatory sharks [strictly not tautonymous with Squalus mustelus Linnaeus 1758 since type was designated by the ICZN]. (See ETYFish); fasciatus: Latin for banded, referring to vertical dark bars on body (at least in young). (See ETYFish).

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Longer snout relative to the size of the eye, head more flattened. Back brown with narrow transverse bands of darker separated spaces. Yellow spot in front of each eye above each orbit. Fins dark with narrow edgings lighter. Lower surfaces whitish (Ref. 6032).

Found on the continental shelf. Newbies are found on beaches of between 1 and 5 m depth, juveniles occupy inshore waters at between 15 and 50 m, and adults are found down to 50 and on upper slopes of up to 250 m in depth (Ref. 56500). Presumably feeds on crustaceans and other benthic invertebrates. Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Size at birth at or below about 39 cm. Utilized fresh-frozen and dried salted for human consumption.

Estimates based on models

Preferred temperature (Ref. 123201): 10.5 - 18, mean 14.5 °C (based on 166 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00224 (0.00105 - 0.00478), b=3.14 (2.97 - 3.31), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.2 ±0.7 se; based on diet studies.

Weerstandsvermogen (Ref. 120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec = 4).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Prijsklasse (Ref. 80766): Medium.
