Summary

This document provides information on: (1) the effect of natural processes and factors on the abundance and distribution of forage species (euphausiids, or krill) that are likely to impact the distribution of blue whales, and (2) the impact of human activity on the dynamic of some of the ecosystem’s key species and the consequences of this on the whales’ use of resources.

Issue: Forage species – Krill distribution
