Analisis Makrozoobentos pada Ekosistem Mangrove di Kabupaten Barru
Abstract
Kata Kunci: Makrozoobentos, kelimpahan, keanekaragaman, keseragaman, dominansi
Makrozoobentos is commonly used as an indicator of an environment polluted waters because it has sensitivity and provide reaction to the changes that occur. In addition makrozoobentos has low mobility so easily influenced by the environment. The result brings an abundance of total individuals in the density of rare, medium and solid in a row is 45,76 individual/m2, 30,12 individual/m2 and, 30,08 individual/ m2, Index makrozoobentos fauna diversity in all plots category low (0.09-0.37), uniformity of makrozoobentos, stable especially gastropod Sinum maculatum (6.50-11.06), Tricolia affinis (6.00-7,59). The home is Tellina radiate (0.02-1.24). Next the Sipuncula Phascolosoma lurco represented (0.07-0.64), Polychaeta represented by Eunice fucata (0.03-0.09 ind/m2). Crab Sesarma sp (0.04-0.11) and Uca sp (0.12) and the dominance of makrozoobentos, a good type of gastropod include Cerithidea quadrata (0.04-0.10), Crepidula convexa (0.04-0.10), Margarites cinereus (0.00-0.01), Telescopium mauritsi (0.02-0.05) and Urosalpinx perrugata (0.02-0.09). The home dominance in every good mangrove density. Next the Sipuncula Phascolosoma lurco represented (0.03-0.16), Polychaeta represented by Eunice fucata (0.00-0.06). Crab Sesarma sp (0.02-0.06) and Uca sp (0.01)
Keywords: Makrozoobentos, abundance, diversity, uniformity, dominance
