Just 100 cod left in North SeaThen the subtitle said:
Overfishing has left fewer than 100 adult cod in the North Sea, it was reported.
This is different than "100 cod" - not all are adult. Perhaps the author changed his or her mind as he/she went along writing the article. Perhaps by fewer than 100 adults he/she meant to say something like 98 adults, which leaves 2 juveniles... Nevermind. The caption under the figure in the article said:
Not a single cod aged over 13 was caught in the North Sea last year.
Most cod is mature before the age of six.
