The jury is still out on the fate of the blue whale. While the ban on commercial whaling has likely aided blue whale population recovery, blue whales are still prone to a myriad of threats and are far from a full recovery. Tantamount to this recovery are abundant and available food resources throughout there entire range, and this is where blue whales might be hard off as they have all their eggs in one basket by foraging exclusively on krill. My organization, Oceana, recently released a report entitled “Hungry Oceans: What Happens When the Prey is Gone?” (available at www.oceana.org/prey) that elucidates the vulnerability of blue whales, and many other marine mammals, seabirds, and predatory fish, to shortages in their main food supply due to overfishing, climate change, and aquaculture. Krill, for example, are known to be sensitive to changes in climate. Reductions of prey resources in this way, combined with intense fishing pressure, could be devastating for blue whales and other marine life that depend so greatly on krill. NOAA should finalize the proposed ban on krill fishing along the west coast to safeguard the resources that these animals so critically need.
