The given table provides data, in metric tons, on local catches versus imports as well as the amount of fresh fish in the Australian city of Perth over a ten-year period, from 2004 to 2014.
Overall, it is clear that Perth is most likely dependent of local fish. Indeed, over the decade, the quantity of local fish in metric tons was significantly higher than that of imported products.
Regarding the period, although both categories experienced fluctuations, the total figures sharply increased, rising from 3142.2 metric tons at the beginning, to 5814.7 metric tons at the end of the period.
Looking more closely, the quantity of local fish went through two distinct stages during this time. During the first four years, the amount of local fish skyrocketed, even has increased threefold, from 2677.7 metric tons caught to 8136.2 in 2008. Following this peak, there was a terrible decline until 2014 to a figure of 5031.9 metric tons of fish.
In the contrast, the amount of imported fish has known ups and downs during the time, although the numbers remain higher in 2014 than in the beginning.
