The table illustrates how the amount of three distinct types of fish farmed in a specific region varied from 2008 to 2018.
Overall, figures for all three fish species listed experienced an upward trend, albeit to varying degrees, with rainbow trout being the lowest throughout the entire period.
In 2008, arctic char dominated the chart, being produced in significantly greater quantities than other species of fish, with a figure of 3,124 millions of tonnes, then it saw a notable decline to 2,427 millions of tonnes by 2010. However, after that this figure rebounded, reaching 3,089 millions of tonnes in 2014, and continued to rose steadily thereafter. By 2014, production had increased to 3,144 millions of tonnes, with a marked acceleration in production observed in subsequent years, finally reaching 4,914 millions of tonnes by 2018.
Meanwhile, the salmon varieties experienced a remarkable growth pattern. In 2008, the amount of salmon produced was 292 millions of tonnes. After that, its production experienced a significant increase to 1.068 millions of tonnes, then it continued to rose gradually and reached 3965 in 2014. The most considerable growth was between 2016 and 2018, where production surged from 8,420 to 13,448 millions of tonnes, thereby having the highest amount of fish produced compared to other species. In contrast, rainbow trout, began at lower levels 6 millions of tonnes in 2008, experiencing fluctuations then increased to 422 millions of tonnes in 2012. Notably, the data indicates that a steady rise particularly from 2014, achieving peak production in 2016, with a 2,138 millions of tonnes. It fell continuously to the end of the period in 2018, with a 295 millions of tonnes
