Abstract

Regulating the fuel consumption of small-scale fishing vessels could help to keep global warming well below 1.5 °C and lead to effective management in small-scale fisheries (SSF) of developing countries like India. In this regard, a bottom-up approach was carried out to collect the requisite data to explore the fuel consumption of small-scale fishing vessels along India's southeast coast. Consequently, twenty-four fishing vessels (type A to type X) were grouped into seven categories based on fishing methods. The estimated numerical value of fuel use intensity (FUI) ranging from 0.08 to 0.80 was used to examine the fuel-efficient fishing vessel and engine type. In addition, the estimated revenue on fuel ranging from ā‚¹5625.06/l to ā‚¹218.07/l and annual greenhouse gas (GHG) emissions using the Tier 1 method were used to understand the economic efficiency and GHG emission trend, respectively. The total annual GHG emissions from all the fishing vessels at the selected sites were about 1.25Eā€‰+ā€‰08 t CO <subscript>2</subscript> -eq year <superscript>-1</superscript> . The result shows that longline-cum-gillnetters, seine-netters, longliners and drift-gillnetters largely contributed to 65% of the annual GHG emissions. By recognizing the factors influencing the fuel consumption of fishing vessels in SSF, this sector could be understood, effectively managed, and performed well. Therefore, the possible reasons were extensively discussed through a comparative approach, and potential recommendations for effective management were made.<br /> (© 2023.
