Abstract
This study revealed the results from a life cycle inventory of milkfish (Chanos chanos) fingerlings production in Thailand and a life cycle assessment (LCA). A scope of study was a gate -to-gate of milkfish fingerlings production. Life cycle inventories were performed based on the production of 1,000,000 fingerlings. The assessments of environmental impacts were global warming potential (GWP), acidification potential (AP), eutrophication potential (EP). There were 5 major stations of milkfish fingerlings production including the brood stock, breeding, nursery, live feed, and support station. The brood stock station exhibited the highest GWP at 51,128.38 kg CO2 eq. The major source of GWP was from energy consumption. The highest AP was from breeding station at 12,794.75 kg SO2 eq. The major source was from energy used for aeration and water pumping. The highest EP was from breeding station at 172,796.10 kg PO4 eq. The use of feeds that contained lower fish meal and a good administration of feeding process could help to reduce the global warming potential. Application of alternative energy sources such as wind energy could decrease global warming and acidification impact. Copyright © 2021 by the authors.
