Post-harvest handling / processing of fishery commodities requires large amounts of water and energy to overcome their perishable properties. Water is needed to be raw/auxiliary material and to ensure the production process and its environment meet sanitary and hygiene principles. Meanwhile, large energy is required for transportation of raw materials and products, cold chain system during the process and operate processing machines. The use should contribute environmental impact of fish processing. This study used LCA to estimate the potential environmental impact of small scale mackerel fish processing in boundary of fish catch and processing. The results showed that the fish processing has contributed to 0.079 kg SO2 eq acidification potential, 9.66 kg CO2 eq climate chang-GWP 100, 0.02 kg PO4-eq Eutrophication-generic, 0,17 kg 1.4 DCB eq human toxicity-HTP inf, and 0.0015 kg ethylene eq photochemical oxidation-high NOx. Wastewater treatment implementation simulation showed eliminating of direct emissions that contribute to eutrification but increasing that potential of other process associated with energy consumption.
