the total global fishmeal production of 6 604 229 tonnes in 2004, and 893 400 tonnes of
fish oil (Figure 41) or 82.2 percent of the total global fish oil production of 1 085 674
tonnes in 2004 (FAO, 2006a).
The data presented in Table 4 show that the estimated global fishmeal and fish oil use
within compound aquafeeds has increased
almost two-fold from 1995 to 2004, rising
from 1 728 to 3 452 thousand tonnes in
the case of fishmeal and from 494 to 893
thousand tonnes in the case of fish oil.
Within the Americas, fishmeal and fish
oil use within compound aquafeeds in 2004
was estimated to be as follows:

• Salmon: total production, 554 511
  tonnes; feed use, 720 000 tonnes;
  average fishmeal content, 35 percent;
  fish oil content, 25 percent; estimated
  fishmeal use, 252 000 tonnes; fish oil
  use, 180 000 tonnes; total, 432 000
  tonnes;


• Shrimp: total production, 294 227
  tonnes; feed use, 455 000 tonnes;
  average fishmeal content,
  22 percent; fish oil content,
  2 percent; estimated fishmeal
  use, 100 100 tonnes; fish oil
  use, 9 100 tonnes; total, 109
  200 tonnes;


• Trout: total production, 173
  514 tonnes; feed use, 225
  000 tonnes; average fishmeal
  content, 30 percent; fish oil
  content, 17.5 percent; estimated
  fishmeal use, 67 500 tonnes;
  fish oil use, 39 500 tonnes;
  total, 107 000 tonnes;


• Catfish: total production,
  291 572 tonnes; feed use,
  467 000 tonnes; average
  fishmeal content, 5 percent;
  fish oil content, 1 percent;
  estimated fishmeal use,
  23 400 tonnes; fish oil
  use, 4 700 tonnes; total 28 100
  tonnes;


• Tilapia: total production,
  155 150 tonnes; feed use,
  210 000 tonnes; average
  fishmeal content, 5 percent;
  fish oil content, 1 percent;
  estimated fishmeal use,
  10 500 tonnes; fish oil use,
  2 100 tonnes; total 12 600
  tonnes;
