Trophic Catch Analysis		You can also enter your own data.
This tool allows you to visualize the catch composition from various areas with respect to trophic levels. It also allows you to compare past with recent catch compositions, typically showing an increase of catches at lower trophic levels. Select the areas and years that you are interested in and click on ‘Trophic pyramid’ or ‘Mean trophic level’. Note that you can also analyse your own data. Please be patient because running the analysis may take a few minutes.
