RECRUITMENT AND DEMOGRAPHIC VARIABILITY IN A LAGOONAL POPULATION OF THE BLENNIID FISH LIPOPHRYS PAVO

The demography of a lagoonal population of Lipophrys pave over a four year period is described. This population exhibited high variability i n recruitment and mortality and as a result, in age structure and dens ity. During the study the average size at a given age decreased. This decrease was not linked to growth variation. Changes in demography and length structure are interrelated and could be linked to stressful en vironmental conditions and to reproductive patterns of this species.
