Part A: Aquaculture Around the World

Some popular seafood such as salmon and shrimp are farm raised in addition to being fished in the wild. Other popular seafood items such as tilapia, catfish and mussels are almost always produced by aquaculture methods. The United States currently ranks tenth in the world in aquaculture, producing approximately 500,000 metric tons of seafood per year, worth almost $1 billion.
  1. Open the file 2005 U.S. Aquaculture Production (Excel 19kB Oct12 07) in Excel or a similar spreadsheet program. Examine the data table.
  2. Create a pie chart to visually examine how much each species contributed to the total U.S. aquaculture production in 2005.

    Answer the following questions to check your understanding of the information provided in the 2005 U.S. Aquaculture Production spreadsheet.



  3. Of the six million metric tons of seafood consumed in the U.S. each year, about four million metric tons is imported from other countries. About half of the imported seafood is from aquaculture. The Food and Agriculture Organization of the United Nations (FAO) provides a comprehensive global view of capture fisheries and aquaculture. Examine the charts below showing 2004 aquaculture production by world region.

    Stop and Think


    1: In 2004, global aquaculture production totaled 59.4 million tons. What percentage of this production was freshwater fish? How does this compare to the percentage of U.S. aquaculture accounted for by freshwater fish (channel catfish, rainbow trout, and American yellow perch) in 2005?

    2: What was the global value of crustaceans in U.S. dollars per ton in 2004?

    3: What was the total value in billions of dollars, of world aquaculture production in 2004?
