Issue Date: | 2003 | Publisher: | 0175-8659 | Journal: | Journal of Applied Ichthyology | Abstract: | The yearly nature of increment formation in the otoliths of 1–9‐year‐old seabream, Diplodus vulgaris (E. Geoffrey Saint‐Hilaire 1817), from the Canary Islands was validated. The marginal increment method showed that the opaque rings were formed in summer, and the translucent rings in winter. The Brody Proportional Hypothesis and the power length–radius relationship used to back‐calculate the growth trajectories of D. vulgaris showed that this growth model could provide reasonable growth estimates in this species. Growth back‐calculation and growth estimates obtained by direct otolith readings were similar. Data on age and size used to estimate the parameters of the von Bertalanffy growth model for D. vulagris from the Canary Islands showed that males and females had similar growth rates. | URI: | http://hdl.handle.net/10553/51830 | ISSN: | 0175-8659 | DOI: | 10.1046/j.1439-0426.2003.00359.x | Source: | Journal of Applied Ichthyology [ISSN 0175-8659], v. 19, p. 79-83 |
