The study looked at how changes in exchange rates affect the prices of farmed salmon when they are exported. They found that the prices of salmon are influenced by changes in exchange rates, with some currencies having a bigger impact than others. For example, the prices of salmon from Chile and the UK are more affected by currency changes than those from Norway and other countries. The researchers also discovered that the drop in the value of the Chilean peso played a role in the decrease in salmon prices in 2003-04.
