Possibility Of Using Sonneratia Caseolaris (L.) Engl) In the Aquaponic Model with White Shrimp combined with Tilapia

Abstract

The Aquaponic system has been widely implemented in various locations, primarily in freshwater environments, requiring adaptation to be compatible with saltwater ecosystems. The objective of this research is to explore the wastewater treatment capability of the Sonneratia caseolaris in a saltwater environment when applied to a recirculating aquaponic model for white-leg shrimp cultivation. The investigative process involves cultivation and determination of the water treatment coefficient of the Sonneratia caseolaris. The environmental parameters under scrutiny include NH4 +, NO2 −, NO3 −, and total phosphorus per gram of plant biomass. Phase 1 consists of seedling production and model design; when the plants reach three months old, they will be tested with shrimp wastewater to assess their treatment capabilities. The results will provide parameters for operating the model in Phase 2. In Phase 2, the aquaponic model involves shrimp tanks (300 shrimp/1 m3), fish tanks (50 fish/0.5 m3), and the plant’s cultivation system. In Phase 1, the plant demonstrated treatment efficiencies of 90% for NH4 +, 95% for NO2-, 32% for NO3 −, and 27% for total phosphorus after 7 days. The treatment coefficients achieved were as follows (mg/g plants biomass): NH4 +: 0.006, NO2 − 0.005, NO3 − 0.017, total phosphorus: 0.057. Transitioning to Phase 2, the results confirm that the aquaponic model, incorporating Sonneratia caseolaris for water recirculation in shrimp farming, is not only technically feasible for small-scale aquaponic models but also scalable for large-scale farm production. Furthermore, the leaves and fruits of Sonneratia caseolaris can serve as a supplementary herbal source for aquaculture species, enhancing the economic sustainability of the recirculating model.
