OECD countries reached 22.8 million tonnes in 2005, accounting for around 23% of total world marine capture fisheries production (Figure I.1). However, OECD production continued its long term downward trend which has seen production decline by an average 3% a year from a decade ago. In 2005, the value of OECD marine capture production totalled USD 31 billion. Declines in production have mostly occurred in a number of EU countries, Japan and the United States (Figure I.2). Denmark, Greece and Japan suffered the largest decreases in marine capture production while Canada, Australia and New Zealand all raised their tonnages by an average of 1% or more per year between 1995 and 2005. Japan, the United States, Norway and Korea are the largest marine fisheries producers amongst OECD countries, accounting for 59% of total OECD production (Figure I.3).
