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.
Highlights
Milkfish (Chanos chanos) is one of the most important aquaculture species among the countries in Asia including, Indonesia, Philippine, and Taiwan [1]
Life cycle assessment (LCA) is the common tool that can help to contribute to creating the sustainable aquaculture system [7]
The goal of this study was to evaluate the information of natural resources using, energy consumption and environmental burden derived from the milkfish fingerlings production unit by using life cycle assessment (LCA) method
Summary
Milkfish (Chanos chanos) is one of the most important aquaculture species among the countries in Asia including, Indonesia, Philippine, and Taiwan [1]. The cultivation of milkfish can contribute in marine, estuarine, or fresh water aquatic systems due to the fact it is the euryhaline fish that can survive in broad range of salinity of aquatic system [2]. This provides the consistently increase in cultivations of milkfish. Culture of milkfish needs fingerlings that are supplied from farms and catching the fries along the coastal area [2]. Philippine is the major country that produces milkfish processing [2]
