Title

Growth and secondary production of the Mediterranean gorgonian Paramuricea clavata

Abstract

Growth and secondary production of the shallow-water gorgonian Paramuricea clavata (Risso, 1826) were investigated at an infralittoral rocky station located at the northern entrance of the Strait of Messina (Tyrrhenian Sea, southern Italy). Colonies were aged by counting the number of annual growth rings at the base of the skeleton. Mean annual linear growth rates were calculated both by field measurements (tagging) and by fitting a Bertalanffy growth equation for the species. Growth rates were 2.7 and 3.0 cm yr^-1 respectively. Secondary production was estimated by means of an increment-summation method. The estimate was quite conservative, because it did not take into account production lost by nonlethal predation, and yielded 3.0 g ash-free dry weight (AFDW) m^-2 yr^-1. Standing stock biomass was 22.5 g AFDW m^-2. Annual P/B ratio was 0.13, and turnover time 7.5 yr.
