Salmon remains the second largest import category, valued at USD 1.6 billion in 2007. The major fresh and frozen commodities were salmon (327.4 million pounds valued at USD 467.1 million), surimi (310.6 million pounds valued at USD 289.9 million), and lobsters (60.7 million pounds valued at USD 390.9 million). The United States recognizes that, without sustainable fisheries, there can be no long-term, commercially viable trade in seafood. Therefore, the concepts of conservation and sustainability are at the core of US trade policy. Additionally, the United States takes the position that tariffs and quantitative restrictions on trade are, for the most part, ineffective substitutes for good management.
