Environmental Assessment of Giant Freshwater Prawn, Macrobrachium rosenbergii Farming through Life Cycle Assessment

The giant freshwater prawn (GFP), Macrobrachium rosenbergii has emerged as a significant crustacean in global aquaculture. A cradle-to-farm Life Cycle Assessment (LCA) was used to assess the potential environmental impacts of GFP Malaysia. four main iterative farming phases involved were pond preparation, stocking, farming, and harvesting. impact categories chosen warming, terrestrial ecotoxicity, acidification, eutrophication, human non-carcinogenic toxicity, carcinogenic activity, water consumption. software SimaPro 9.3.0.3 for analysis, with background data from database Ecoinvent 3.0. ReCiPe 2016 Midpoint (H) V1.06/World (2010). Among other categories, stocking harvesting contributed toxicity values 33.33%, followed by (33.31%). Another category, ecotoxicity also produces same pattern process, still generating highest value 33.34%, (33.30%). Apart identified capital items that require consideration future waste management aquaculture, this LCA study found M. generates low environment, however, could inspire further research on perspectives sustainability.
