Cod

, following a moderate increase , reached roughly 170,000 in 2002, it decreased to 149,000 in 2007; it remained the biggest bunch of fish. Returning to the facts for Haddock and Swordfish, what stands out from the scheme is that they were in the third and fourth places with 100,000 and approximately 10,000 in 1982, respectively. Surprisingly, both were completely steady with no fluctuation; so, they had these numbers exactly in 2007.
