Study of the Relative Growth of Bivalve Cardium costatum (Linné, 1758) of the Exclusive Economic Zone of Côte d'ivoire

This study was to determine growth parameters in order to provide important data for better planning of the sustainable management of maritime resources and initiate shellfish farming.

A total of 540 individuals from the exclusive economic zone of Côte d'Ivoire were sampled from November 2012 to October 2014. The measurements were carried out in order to study the allometric relationships concerning the height-length, height-thickness relationships, thickness-length, weight-length, weight-height and weight-thickness. The results reveal that linear growth exhibits negative allometry (b < 1) in Cardium costatum. This species grows faster in length than in height and thickness. The weight growth of Cardium costatum presents a positive allometry (b > 3). Which means that this species grows faster than it lengthens.
