  • Atlantic Ocean species Catch

    Species in the western Atlantic Ocean

    Five species fill up just over 50 percent of the fisheries in the northwest Atlantic Ocean.

    The Northern prawn is the biggest factor, counting for 17% of the total catch.

    The American sea scallop is the sexond biggest factor, 14% and the Atlantic herring is at 11%. The Atlantic menhaden is at 10%.

    The picture on the rights shows the number for 2008.

    In the northeast Atlantic Ocean, which stretches around Europe, the Atlantic herring is by far the biggest factor. It counts for almost 30% of the total catch.

    The blue whiting, is also popular, at 16% and the Atlantic cod is only at 9%.

    Catch by species in the northeast

    Herring is the biggest factor in the northeastern part. Along with blue whitting and the cod they count up for 50% of the total catch.

    Six other species fill up approximately 25% of the total catch, the Atlantic mackerel, European sprat, aithe (Pollock), Sandeels (Sandlances), Haddock and Capelin.

    Others are numerous but count for much less.

    The Atlantic herring is important both in the east and the west, but other species are not as connected between the two sides.

  • Atlantic and Pacific Ocean Catch

    Atlantic ocean catch in total 2011

    The first graph shows the Atlantic Ocean. The blue colour is the northwest and the orange for northeast.

    To see the total number of tons cought gives a good overview of fishing in the Arctic.

    Here is a map that shows the oceans and how they are divided by east and west.

    The numbers are in tons and show comparison between decades. The first ones are from 1950 and the last ones from 2008.

    The colours show how much more is is caught in the northeast. One could say that the northeast is Europe and the northwest Canada and Greenland, but Greenland actually accounts for numbers both in the east and the west.

    In Europe countries like Spain, Portugal and England all catch alot of fish and make up the numbers with many other states

    Catch in the Pacific Ocean 2011

    The graph shows that there is not necessarily a connection between the east and the west in quantity of fish cought. There are of course many reasons for this.
    One can be the dependance on fisheries with the nations. The number of states is also a big factor, one set of numbers is only for a part of USA, Canada and Greenland, but the others for many countries in Europe.

    Since 1970, quantity has decreased in the northwest. This is for USA, Canada and Greenland and could mean that with increased tecnhnology, fisheries are not as important as before.

    One can also see that the difference between the numbers from 1950 and 2008 are very little, which shows the need for fish and his importance.

    The second graph shows the Pacific Ocean. The blue colour is the northwest and the orange colour is northeast.

    The difference between the east and the west is even greater in the Pacific Ocean, but vice-versa from the Atlantic where the eastern nation catch more.

    Again there appears to be little relation between the east and the west.

    But this shows that both the east and the west fish more today then in 1950.

    The numbers in the west grew significantly until 1990, but then started to fell.

    The difference in the east is not that much since 1970 to 2008.
