6 History of Aquaculture
Egyptian tombs have bas-relief of fish (tilapia) being removed from ponds 2500 B.C.
Carp were farmed in China as early as 2500 B.C.
Wen Fang founder of the Chou Dynasty is called the first fish farmer (during exile he kept records of fish growth and behavior)
Fan Li wrote first book on fish farming 475 B.C.
Lee family Were the first to polyculture carp during the Tang Dynasty 600 to 900 A.D.
England 1500 A.D. carp culture was introduced

12 Current Aquaculture Production
Aquaculture is the fastest growing sector of U.S. agriculture with an approximate annual growth rate of 10
Currently aquaculture accounts for 25 of all seafood consumed in the U.S.
13 World Aquaculture Production
In 2000 45.51 million metric tons by weight of aquaculture products
Equal to US 56.47 billion
China is the largest aquaculture producing country in the world
14 Proportion of Total Aquaculture Production for Different Taxonomic Groups 15 Percent of Total Food Fish Supplied by Aquaculture 16 Aquaculture Production Ocean Fisheries and Fishmeal Production 17 Why Aquaculture Products
U.S. or locally grown (Exclusive Economic Zones)
