The trawlers go after pods of spouting whales because they know there’s krill. To protect the world’s largest creatures, we have to protect the world’s smallest creaturesAlthough legal, krill fishing’s links with environmental destruction require greater attention, says captain Peter Hammarstedt, director of campaigns for
Whales and krill are intricately connected, with a previous Stanford study finding that whales fertilise the ocean through their droppings, providing nutrients for the phytoplankton that krill eat. The rise in krill fishing is also linked to an increase in aquaculture as wild fish populations decline. The flesh of wild salmon is naturally pink because they eat krill and other small crustaceans, but farmed salmon will be grey unless fed additives. Hammarstedt says, “Although it will taste exactly the same as wild salmon, people are not going to buy grey salmon flesh at supermarkets.”
Sea Shepherd will return to Antarctica in spring 2025, supported by a campaign to map out the krill supply chain, connecting products and business choices with their impact on whales.
