With care for the environment
CO2-emissions is regarded as one of the main environmental challenges in our time. The fuel consumption of hauling a 10-millimeter longline rope versus operating a bottom trawl is calculated to be less than 50 % per kilo catch, and in average one kilo of wild caught cod produce only 10 % of the carbon footprint as one kilo of beef[1].
Vulnerable bottom areas such as coral reefs have been treated by human activities. In a large scientific study lead by United Nations scientists, Longline fishery is evaluated to have a minimal benthic impact compared to other demersal fishing methods [2].
Ghost fishing is another environmental challenge caused by fisheries activity and is almost non-existent in Longlining. When hooks are rid of bait they are not attractive to fish anymore and will consequently not catch fish[3].
