Abstract

This study investigated the GHG emission from 3 processes of white leg shrimp production in an intensive shrimp farm; namely, pond preparation, culturing and harvesting at the density of 50,000-60,000 individuals/rai in March-May 2019. The activity data such as energy and materials use, waste and water discharge were collected and greenhouse gas emission calculated. Results showed that overall GHG emission for 1 crop was 4.33 kgCO2eq/kg product for which the cultural stage produced the highest amount of 3.63 kgCO2e/kg. The use of electricity from aeration, auto feeding and lighting in the cultural stage was 83.58% of total GHG emission. If intermittence aeration was applied and the light bulbs were decreased in number and wattage, the total amount of GHG emission could be decreased by 9.88%.
