Although transport is clearly a major issue in the life cycle of some fish products, this paper finds that the actual fishing stage of the life cycle is by far and away the most significant from a GHG emissions perspective.

The Sea Fish Industry Authority in the U.K and Dr. Peter Tyedmers of Dalhousie University have created a greenhouse gas emission profiling tool for seafood products from capture fisheries. The purpose of this tool is to allow users to explore the carbon implications of sourcing and supplying seafood. This will provide a better understanding of the major contributors to the "carbon footprint" of seafood products. It also provides insight into the influence that some aspects of the seafood production chain have on carbon emissions.

This paper discusses the role of fuel subsidies to the fishing industry and argues that the fuel subsidies can maintain over capacity and unsustainable harvesting of fish in times of inflated fuel prices. The abstract is below. Global fisheries are currently overcapitalized, resulting in overfishing in many of the world’s fisheries. Given that fuel constitutes a significant component of fishing costs, we expect recent increases in fuel prices to reduce overcapacity and overfishing.

This paper calculates that fisheries account for about 1.2% of global oil consumption and directly emit over 130 million tonnes of CO2 into the atmosphere.

This paper explores the scale of energy consumed by most segments of the Norwegian fishing fleet for gadoid fish and for parts of the pelagic fleet for the period 1980–2005. Possible means of reducing energy use and emissions are discussed including changing operational strategies, hull forms and the use of alternative energy carriers. The use of liquefied natural gas is reported to be the best short term solution which could give a reduction of the discharge of NOx of 85% and CO2 of about 20%.

This report gives valuable data on energy use in a range of fisheries types across the world, showing the energy intensity of fish production. It shows large variability across sectors and within a sector, between locations and fishing methods.
