Abundance of cold-water fish species (arctic, mainly arctic and arcto-boreal groups) decreased from 2000-2001 to 2010. But since 2011, slight increases in abundance of these groups have been observed.

But since 2011, slight increases in abundance of these groups have been observed.
At the same time abundance of warm-water (boreal, mainly boreal, southern boreal and widely distributed groups) fish species have trended to increase.
The highest abundance was observed in 2001-2004 and 2008-2010. Since 2008 a clear tendency to decrease has been observed for these groups. However, as mentioned above, the abundance of blue whiting increased again in 2012.
