摘要

The present study examines sustainability concerns in India’s motorized fishing sector by focusing on economic performance and environmental impacts, particularly carbon dioxide (CO₂) emissions. A proportionate random sampling technique was employed to select 109 fishers operating across five motorized fishing systems: Single-day Gill net (SDG), Multi-day Gill net (MDG), Single-day Long line (SDL), Multi-day Long line (MDL), and Boat Seine (BS) in the Pulicat region of Tamil Nadu, a south-eastern coastal state of India. Primary data on operational characteristics, costs and returns, and fuel consumption were collected through in-person surveys using a structured interview schedule designed specifically for the study. Fuel-use intensity was used as an indicator of energy efficiency, and CO₂ emissions from fishing systems were estimated using a standard conversion factor of 2.675 kg CO2 per litre of fuel consumed. Economic analysis revealed that the benefit-cost ratio (BCR) was greater than one for all five fishing systems, indicating overall economic viability. Among them, MDL fishing system exhibited the highest profitability with a BCR of 1.33 and a net profit margin of 24.94%. Annual fuel consumption and CO2 emissions were highest for BS (28,554.2 lit; 76382.59 kg), and lowest for SDG (4273.5 lit; 11431.61 kg) fishing systems. However, fuel consumption and CO2 emissions per ton of fish harvested were found to be better for BS (202.07 lit; 540.54 kg CO2) fishing system. Overall, the findings suggest that while BS fishing exhibits better energy efficiency, the MDL fishing demonstrates a more balanced profile when economic performance and sustainability considerations are jointly evaluated. The study provides evidence-based insights to support policymakers and fisheries stakeholders in promoting economically viable and environmentally responsible fishing practices in the Pulicat region.
