Mangrove ecosystems have considerable potential as natural phytoremediation agents for reducing nutrient loads from shrimp aquaculture wastewater; however, their effectiveness depends on species-specific characteristics and nutrient accumulation patterns within plant organs. This study aimed to analyze the quality of shrimp pond effluent in Legung Village, Sumenep Regency, evaluate the effectiveness of mangroves in reducing nitrogen and phosphorus concentrations, and identify nutrient bioaccumulation in roots, stems, and leaves. A natural experimental approach was employed by collecting water samples along the wastewater flow path and mangrove organs through purposive sampling. Data were analyzed using the Shapiro–Wilk test, One-Way ANOVA or Kruskal–Wallis test, Tukey HSD post hoc test, removal efficiency, Bioconcentration Factor (BCF), and Translocation Factor (TF). The results indicate that mangrove ecosystems effectively reduce nutrient concentrations, although remediation performance varies among species. The novelty of this study lies in integrating water quality assessment, phytoremediation efficiency, and bioaccumulation mechanisms of two dominant mangrove species within a single coastal ecosystem. These findings provide a scientific basis for developing mangrove-based wastewater management strategies to improve the sustainability of shrimp aquaculture and protect coastal water quality.
