The given table illustrates local fisheries 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, Perth depended mostly on domestic fishing, with quantities of fish from their fisheries significantly higher than that of imported fish. Notably, the total volumes of fish increased greatly until 2009 and then dropped off.
The total volumes of fresh fish rose dramatically in the first five years, starting at 3142.2 metric tons in 2004 and peaked at 8949 metric tons in 2009. Considerably, fresh fish importation reached its highest in the same year with 1104.1 metric tons. However, with local catches, it reached the high point of 8136.2 metric tons the year before, in 2008. Still, in all given years, the volumes of domestic fishing were always greater than that of imports.
Following this peak, local catches experienced a terrible decline until 2014 to a figure of 5031.9 metric tons of fish. Similarly, fresh fish from imports fell down to 782.7. 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.
