Digha Mohana is a major fish landing and auction centre on the Northeast coast of India that supports livelihood and contributes to fisheries export. Trawl fishing is the major fishing operation observed in the region, where multi-day operations (MD) less than six days and > 6 days are in practice. In this study, we collected primary data on input and output factors in these two fleets to investigate the economic efficiency in fishing operations for 2018-2019. In this case, it is essential to study the economic efficiency of the trawls to sustain both the fishing industry as well as the marine environment. The analysis revealed that the mean cost incurred per fishing day was high for more than 6 days than MD (<6 days) fishing. MD trawlers (<6 days) were found to be labour efficient as well as earned more carbon credit by releasing less carbon dioxide during fishing operations in terms of fuel quantity and the value as compared to MD trawlers (> 6 days). The economic efficiency assessed through the different indicators revealed that the trawl operations were profitable with more than 6 days than the less than 6 days operations
