- Abstract
A synthetic analysis of the distribution, abundance and some biological traits of the common pandora ( Pagellus erythrinus) was performed. Data were gathered in 15 experimental bottom trawl surveys carried out off the southern Tyrrhenian Sea from 1994 to 2008. A total of 2,166 P. erythrinus were found in the investigated area, with a preference for the upper continental shelf (10-100 m). The highest persistence was recorded in the trawl-banned areas. The sex ratio Sr = F/( F + M) ranged between 0.60 and 0.96 (overall 0.78). The size at which 50 % of the individuals were mature was 157 and 170 mm total length for females and males, respectively. The length-weight relationship for all individuals was described by the following parameters: a = 0.016 and b = 2.905. Growth was evaluated (sexes combined) by applying length-based methods; up to eight significant modal components were evidenced. The von Bertalanffy growth parameters for the whole population were estimated at L = 454 mm, K = 0.08 and t = −2.57. The present results are in agreement with the information available for the other Mediterranean stocks suggesting common biological features.
