IV.3.5.5. The underwater seagrass beds and coastal underwater formations:
The Posidonia seagrass meadows along the coast of Skikda province are widespread,
particularly between Hadjra Sidi Mahchich and Monkey Islet, the cliffs of Filfila, and between
El Marsa and Akkecha Islet. The extent of the Posidonia seagrass is limited in depth, where it
reaches a sparse formation down to 40 meters deep (MATE. 2005).
The seagrass meadow is grazed by the salema (Boops salpa) and the striped seabream (Spicara
maena). Other fish species benefit from the advantages of the seagrass meadow as a spawning
area: the painted comber (Serranus scriba), the seahorse (Hippocampus ramulosus), the spider
crab (Maja squinado), and the noble pen shell (Pinna nobilis) take refuge at the base of the
seagrass meadows.
