Abstract Energy is a key input into the fish harvesting
process. Efficient use of energy helps in reducing
operational costs and environmental impact, while
increasing profits. Energy optimisation is an important
aspect of responsible fishing as enunciated in
the Code of Conduct for Responsible Fisheries.
Gross Energy Requirement (GER) is the sum of all
non-renewable energy resources consumed in making
available a product or service and is expressed
in energy units per physical unit of product or
service delivered. GER is a measure of intensity of
non-renewable resource use and it reflects the
amount of depletion of earth’s inherited store of
non-renewable energy in order to create and make
available a product or service. In this study, GER in
fish harvesting up to the point of landing is
estimated in selected fish harvesting systems in the
small-mechanised sectors of Indian fisheries and
compared with reported results from selected nonmechanised
and motorised fishing systems to reflect
the situation during 1997-1998. Among the fish
harvesting systems studied, GER t fish-1 ranged from
5.54 and 5.91 GJ, respectively, for wooden and steel
purse seiners powered by 156 hp engines; 6.40 GJ
for wooden purse seiner with 235 hp engine; 25.18
GJ for mechanised gillnet/line fishing vessel with 89
hp engines; to 31.40 and 36.97 GJ, respectively, for
wooden and steel trawlers powered by 99-106 hp
engines.
