The table illustrates the amount of fresh fish caught locally and imported into Perth, Australia, over a 10-year period from 2004 to 2014. The figures are presented in metric tons.
Overall, it is evident that local catches consistently outperformed imports throughout the examined period. Both categories experienced a steady upward trend during the first half of the timeline, followed by a notable decline. The peak year for total fresh fish supply was 2009, while the lowest figures were recorded in 2004.
In 2004, the total fresh fish supply was at its lowest point, with 2,677.7 metric tons sourced locally and 464.5 metric tons imported, amounting to a combined total of 3,142.2 metric tons. Over the following years, local catches increased dramatically, reaching a peak of 7,844.9 metric tons in 2009, while imports rose more modestly to 1,104.1 metric tons in the same year. This marked the highest overall supply of fresh fish, at 8,949 metric tons.
From 2010 onwards, a gradual decline in both local and imported fish supplies was observed. Local catches decreased significantly, from 6,811.4 metric tons in 2010 to 5,011.9 metric tons in 2014. Similarly, imports dropped steadily from 1,203.7 metric tons in 2010, their highest recorded figure, to 782.7 metric tons by the end of the period. By 2014, the total supply of fresh fish had fallen to 5,814.7 metric tons, representing a sharp contrast to the peak in 2009.
In summary, while local catches consistently dominated imports, both categories followed a similar pattern of growth and decline over the 10 years. The year 2009 marked a significant high point for total supply, followed by a sustained decrease in the subsequent years.
