Growth, Dynamics and Stock Assessment of the Common Pandera Pagellus erythrinus (Linnaeus, 1785) from the Southwestern Mediterranean
On the Jijelian coast (eastern Algeria), the evolution of Pagellus erythrinus production was unstable and heterogeneous during the period of 2011-2016, with a fall of about 44.57% in 2015 compared to the year 2011. As a result, the present work aimed to study the population growth and the dynamics and to estimate the current state of the common pandora’s stock. In this bioeconomic study, a total of 307 specimens of P. erythrinus were sampled on the Jijelian coast between March and May 2018 (11.8 ≤ TL ≤ 28.2 cm, 19.52 ≤ TW ≤ 264, 89g). The growth parameters and exploitation indices were estimated using various methods. The retained values were utilized to evaluate the stock of this species (L∞ = 29.55, K = 0.30, t0 = -0.77, a = 0.0143, b = 2.949, Z = 0,891, M = 0.32 and F = 0.571). The analysis of Jones' (1983) cohort revealed that the individuals least targeted by sinners are those smaller than 17cm. In contrast, applying the Thompson and Bell model (1934) indicated that the fishing effort currently calculated (FC = 0.57) expresses that the P. erythrinus stock is overexploited. The recommended reduction in fishing effort to FMSY = 0.4 should be 29.8% for sustainable fishing and resource conservation.
