Over one year study period, stations near the berth line supported relatively lower abundance, diversity and richness than stations near the mangrove edge. Every sampling location along the mangrove edge had a similar configuration, with shallow water (6.8-11.2 m) and high organic content (11.98-17.04%) in a soft and muddy substratum (63.42-73.77) suitable for settlement by diverse species, factors that may cause species abundance to increase.
