Analysis of the relationship between zoobenthos diversity, sediment characteristics, and mangrove density in the Fishery Port Areas of Bireuen Regency, Aceh

Key Points

Zoobenthos diversity positively correlates with finer sediments, showing significant diversity traits in varying sediment types.
Highest diversity observed in Peudada with H'=0.71 while dominance is low, indicating a rich benthic community.
Quadrat and line transect methods used for data collection across three fishery harbors in Bireuen District.
Study highlights the need for integrated coastal ecosystem management to maintain ecological functions in fishery ports.

Abstract

This study examines the relationship between zoobenthos diversity, sediment characteristics, and mangrove density in three fishery harbors in Bireuen District: PPI Peudada, PPI Jeumpa, and PPI Jangka. Data were collected using quadrat and line transects with purposive sampling. Peudada showed the highest zoobenthos diversity (H'=0.71) with low dominance (D=0.27) and medium sand substrate. Jeumpa and Jangka were dominated by tolerant species and coarse sand. True mangrove regeneration was more developed in Jeumpa and Jangka, while Peudada was dominated by non-mangrove vegetation. There is a strong relationship between sediment type, zoobenthos diversity, and mangrove structure. Fine sediments favored benthic diversity, while coarse sediments supported mangrove growth. The findings highlight the importance of integrated coastal ecosystem management to sustain ecological functions in fishery ports.
