Yes. For years, Grizzly Pet Products’ founder Harald Fisker hesitated to introduce krill oil for this very reason. However he was at last able to locate a sustainable harvesting source and method endorsed by both the World Wildlife Fund (WWF) and the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

As detailed under the Krill Conservation Category 51 of the CCAMLR website, krill harvest is only permitted in a section of Antarctica called Area 48—which comprises less than 1/4 of all the waters surrounding Antarctica, and encompasses over 60 million tons of krill.

Within Area 48, CCAMLR permits no more than 9.35% of that available biomass to be harvested.

Of that 9.35%, the entire krill Industry (for both human and pet consumption) harvests 1/3 of 1%—or 0.33%—of the annual limit set by the CCAMLR, resulting in a sustainable krill population to support whales and other sea mammals.
