Life-cycle analysis of wild catch and farmed fish
found no “significant difference” in energy use or global warming
potential, LEI wrote in a report published online today.
Energy use per kilogram (2.2 pounds) of cod or
plaice is higher than for beef, pork or chicken, while the effect on
global warming is similar because of emission of greenhouse gases such
as methane by livestock and manure, LEI wrote. Technologies to curb fuel
use would improve the environmental impact of wild-caught fish,
according to the researcher.
“Both the wild-caught sector and aquaculture can
improve their environmental performance,” the researchers wrote. “The
life-cycle impact of North Sea fishing is linearly related to fuel
consumption.”
Consumers hold fisheries responsible for loss of
biodiversity and environmental damage, LEI said. New fishing techniques
and fuel-saving technology may lead to “significant reductions” in
environmental impact, according to LEI.
“Various relatively cheap whitefish products are
imported in large quantities in Europe and compete with wild-caught,
freshly landed North Sea whitefish,” the researchers wrote. “In France
and Spain, this has already led to serious problems for the domestic
fishing sector.”
To improve the marketing position of wild-caught
fish, more information is needed on how wild catch compares with farmed
fish, according to LEI.
