Phase 2. Estimation of survival rate
Approximately 50 reared recruits and 50 wild recruits will be placed in
separate plots of rocky bottom cover by algae (25m2 of
surface approximatively in relation with natural density). Each plot
will be closed on the edges to prevent sea urchins to leave. The
survival rate of both groups will be estimated differentiating the
causes of death (e.g. physiological causes or predation). In addition,
we will estimate the grazing activity of the two groups by assessing the
algal cover before and after the reseeding.
