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
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.
