VL - 71 IS - 2 SE - Articles DO - 10.3989/scimar.2007.71n2279 UR - https://scientiamarina.revistas.csic.es/index.php/scientiamarina/article/view/7 SP - 279-285 AB - <p align=justify>This study describes the results obtained by applying the Arnason Schwartz multistate mark-recapture model to eight years of data collected in and around a small no-fishing marine protected area (MPA; 4 km<sup>2</sup>) in the central western Mediterranean. From 1997 to 2004, a total of 4044 specimens of <em>Palinurus elephas</em> (Fabr., 1787) were tagged and 317 recaptured. The most parsimonious model which best explained the data variability was that of a temporally constant rate of apparent survival and movement in each of the two strata. The absence of any temporal influence in the apparent survival rate inside the no-take area suggested that spillover and mortality are constant for each period of the study. The lower apparent survival rate in surrounding zones than inside the MPA (0.26 ± 0.04 (SE) vs 0.94 ± 0.03 (SE)) is presumed to be a function of fishing effort. A continuous movement of <em>P. elephas</em> across the boundary of the small MPA was also tested. This information on retention of lobsters in the MPA contributes to our understanding of the effect of introducing MPAs into a managed commercial fishery system.</p> ER -
