Some population characteristics of the pink spiny lobster Palinurus mauritanicus (Gruvel, 1911) caught in the Béni-Saf Bay (Western Algeria)

Abstract

This study is aimed to pinpoint the morphometrics, state of exploitation dynamic in order to assess the P. mauritanicus (Gruvel, 1911) stock. Specimens were caught by trawlers operating in Béni-Saf Bay. In total 121 individuals were collected: 60 males (49.58%) and 61 (50.41%) females, χ2 test (p<0.05) didn’t show any significant difference between the two sexes. FISAT II software was used to estimate growth parameters, recruitment, mortality and exploitation rates. Total length-total weight, total length, carapace length equations parameters for the entire population were respectively TW=0.0363*TL2.858, Log TL = 0.802*Log CL+ 0.631 indicating a negative allometry growth. The parameters of Von Bertalanffy were: L∞ =32.03 cm, K=0.18 yr-1and t0= -0.16 year-1. Total mortality was estimated Z = 0.760 yr-1, natural maturity M=0.458 yr-1, fishing mortality F=0.302 yr-1 and exploitation ratio E=0.397 reflecting a situation near the full exploitation of the resource.
