The charts below show information about the number of fish caught and the number of fishing boats used in Westhaven. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

A glance at the three given bar charts reveals stark of comparison between the number of fish caught and the number of fishing boats used in Westhaven for Tuna fish and Swordfish from 2008 to 2011. It was a shock result that no significant correlation between a numbers of boats with a number of fish caught for both fish. This was a matter of considerable and interesting to find the factors of these phenomena.

To begin with, number of tuna fish rose dramatically from 85.ooo in 2008 to the peak at 110.000 in 2011. This growth constantly happened to 100.000 and 110.000 in 2009 and 2010 respectively. In contrast, the swordfish caught was totally shown a fluctuated trend around 50.000 (2008), 120.000 (2009), 70.000 (2010) and 110.000 (2011). Nevertheless, this swordfish indicated a moderately went up in 2010 to 2011, this fish had already declined from 2009 to 2010 by 30.000 amount of fish. These rare conditions were still unknown what factors influenced with, the environmental or just in case the change of population of swordfish.

Uniquely, both of those caught fish were not correlated significantly with number of boats. For normal reason, this caught should be increased if the number of boats were added. Conversely, this condition was not influenced by number of boat because it showed in 2008 only 50 boats operated to result 85.000 tuna fish and 65.000 swordfish. When fisherman added boats to 55 in 2009, the number of both fish climbed sharply to 100.000 for tuna and 120.000 for swordfish. This condition perhaps was triggered by addition of some machine in those boats. After that, when fisherman reduced boats to 45 in 2010, there were no effect of decreasing for tuna fish. In the last year, 2011, a rising of boats to 70 units changed number caught of both fish to 110.000 for tuna and 100.000 for swordfish.

In my summary, this unique case needed more research to find out the factors of boat that important to improve number of fish.
