Issue
Teshima & Takeshita (1992) studied the reproductive biology of this species, and found that males are usually reproductively mature at 17 to 19 cm DW (the holotype is an adult male of 15 cm DW), and that females are sexually mature between 17 and 21 cm DW and produce one embryo per uterus (born at 10 cm DW). Females give birth throughout the year. Additional references: Castex & Suilar (1965), Thorson et al. (1983a), Rosa (1985a), Compagno & Cook (1995).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.2   ±0.40 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Assuming Fec<10).
Fishing Vulnerability (Ref. 59153):  High vulnerability (58 of 100).
