Obtain and tabulate available data on population sizes and prey
consumption by marine birds and mammals;
Calculate seasonal and annual consumption, expressed as numbers
and biomass, of particular marine resource species by particular
bird and mammal populations;
Where possible, stratify the calculation as to age classes of
prey and locality (local stock impacted);
Prepare a report for PICES describing data sources and methods
of calculation, and the results, and identifying major lacunae
in knowledge.
