Short description Morphology

Shell equivalve, thick and solid, ovate, strongly inflated, slightly longer than high and feebly inequilateral. Umbones strongly protruding, cardinal area rather large. About 18 radial ribs (15 to 20) with wide interstices at each valve; ribs stout and distinctly rugose, bearing regular, often rectangular nodules. Periostracum rather thin and smooth. Internal margins with strong crenulations corresponding with the external radial ribs. No byssal gape. Colour: outside of shell white under the yellowish brown periostracum. Inner side white, often tinged yellow towards the umbonal cavity.

This represents the most important commercial ark (Ref. 348).

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

Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam.

Estimates based on models

Preferred temperature (Ref. 115969): 21.8 - 29.3, mean 28.4 (based on 3701 cells).
Resilience (Ref. 69278) High, minimum population doubling time less than 15 months (K=0.54-4.34; tm=0.6; tmax=12).
Prior r = 0.85, 95% CL = 0.56 - 1.28, Based on 2 data-limited stock assessments.
Vulnerability (Ref. 71543): Low to moderate vulnerability (28 of 100).
Price category (Ref. 80766): Medium.
