Abstract
Contribution of marine fisheries at at Nizamapatnam and Machilipatnam all stages of its life cycle to climate change in 2017 was studied by determining their carbon footprint.Pre-harvest phase consisted of vessel construction and maintenance and provision of fishing gear, harvest phase included harvest from mechanized and motorized crafts and post-harvest phase involved fish transportation and fish processing. The functional unit selected was 1 kg of marine fish to the consumer.Fuel and electricity consumption was 0.52 l / kg and 0.26 kWh/ kg of marine fish at Nizamapatnam and 0.48 l / kg and 0.21 kWh/ kg of marine fish at Machilipatnam. The C and CO emitted per kg were 0.408 kg C and 1.501 kg CO at Nizamapatnam and 2 2 0.374 kg C and 1.374 kg CO at Machilipatnam.The highest consumption of energy and the highest 2 emissions of CO were observed from the harvest phase. The fuel and electricity consumption and C and 2 CO emissions were in general higher for mechanized landings and lower for motorized landings. By 2 increasing the fuel efficiency of marine diesel engines, by controlling craft speed, by using large propeller with lower revolutions and by reducing the craft drag, reduction in energy consumption and subsequent emissions is possible..
