10,000 Pounds of Diatoms for 1 Pound of Tuna

"It has been estimated... that it takes 10,000 pounds of microscopic diatoms, a form of plant plankton, to make 1,000 pounds of copepods... which in turn produces 100 pounds of smelt. When eaten, the 100 pounds of smelt yields one pound of tuna. This one pound of tuna, caught and eaten, increases a person's body weight by a mere 0.1 pound." - excerpt from the book, The Ocean Almanac, by Robert Hendrickson, published by Doubleday, 1984, pg. 1
