“…The habitat utilised by species changes with life history stage, density, competition with other species and environmental variability in time and space. During their early life stages, many species occur in coastal waters in essential spawning and nursery habitats such as seagrass beds (Boudouresque et al, 2006), rocky bottoms (Guidetti, 2000, Vanderklif & Jacoby, 2003 or soft shallow bottoms for flatfishes (Eastwood et al, 2001, Koubbi et al, 2006, Le Pape et al, 2007. These studies emphasised the ecological importance and the protection provided by such habitats in relation to their crucial role as nurseries for many fish species and their overall importance in maintaining littoral fish populations and species diversity.…”
