The given table illustrates the quantity of three particular types of fish farmed in one region over a ten-year period, with two-year intervals, from 2008 to 2018, measured in millions of tonnes.
Overall, the quantity of Arctic char, salmon and rainbow trout experienced an upward trend, even though the amount of Arctic char and rainbow trout witnessed some minor fluctuations. Notably, Arctic char farming recorded the highest figure at the start of the period, but by the end salmon farming was the highest, while the quantity of farmed rainbow trout consistently remained the lowest.
Regarding the first three recorded years of the period, Arctic char farming remained the highest figure after it witnessed a drop from 3124 in 2008 to 2427 in 2010, before rising again to 3089 in 2012. Both salmon and rainbow trout farming followed a similar trend, starting at 292 and 6 respectively, before growing to 2923 and 422 in that order.
As for the remaining years, most of the figures shared the same upward trend, with the exception of rainbow trout. In 2014, salmon farming surpassed Arctic char by 554, after which it rose rapidly to 13,448 in 2018, while the total amount of farmed Arctic char increased steadily to 4914 at the end of the period. In 2014, the amount of farmed rainbow trout grew to 603, before rising dramatically to 2138 in 2016, after which it dropped sharply to 295 in 2018.
