Population biology of the common pandora, Pagellus erythrinus (Linnaeus, 1758) along the Lebanese coast, Eastern Mediterranean

The common pandora, Pagellus erythrinus, is a commercially important seabream for coastal fisheries in the north and central eastern Atlantic. Age, growth and reproductive aspects of the southern Portuguese population were estimated by analysing 386 specimens ranging in total length (TL) from 12.0 to 44.8 cm. Ages were estimated by counting growth bands on otoliths and verified by marginal increment analysis, with specimens ranging in age from 1 to 21 years. The von Bertalanffy growth function was selected as the most adequate model to fit this species' growth, with the estimated parameters being Linf = 47.14 cm TL, k = 0.084 year-1 and t0 = -4.42 year. The gonads were analyzed macroscopically over a one-year period and the reproductive spawning season found to occur from March to July. The length at first maturity for males occurs at 17.58 cm TL and 1.15 years while females mature at slightly smaller sizes (17.29 cm TL) and younger ages (1.04 years). The results presented in this study are important for comparing this population's parameters with those of other populations of the same species occurring in other areas, as well as for future studies, for assessing eventual changes in population parameters over time.

Genetic structure and growth characteristics of common pandora Pagellus erythrinus populations collected from the Iskenderun, Mersin and Antalya Bays were revealed through D-loop sequencing of mtDNA and length-weight and age-length relationships. While the highest value of genetic diversity was obtained in the Mersin population (0.0024), the lowest value was in Iskenderun population (0.0006). A total of 9 haplotypes was found and mean haplotype diversity was found 0.7485. The highest genetic divergence was observed between the Mersin and Iskenderun Bay populations (0.0206), whereas the Iskenderun and Antalya Bay populations had the least genetic divergence (0.0165). BioMorphv3 was used for determining the length-weight and age-length relationships. The length-weight relationships for all individuals of Iskenderun, Mersin and Antalya populations were estimated as W=0.0693 x L 2.3887 (r=0.9456), W=0.0786 x L 2.3338 (r=0.9473) and W=0.0693 x L 2.3887 (r=0.9542), respectively. The von Bertalanffy growth parameters for all individuals of Iskenderun, Mersin and Antalya populations were calculated as Lt=39.22 [1 - e0.210(t+0.32)], Lt=50.48 [1-e0.120(t+2.76)], Lt=38.08 [1-e 0.158(t+0.48)], respectively.
