Exposing the
Krill Fleet

Industrial supertrawlers are draining the food supply every whale, penguin and seal depends on. Sea Shepherd crews are there to document it.

Sea Shepherd / The Crisis

Stripping the Food Web

Krill are the foundation of everything alive in the Southern Ocean. Industrial fleets are taking them at a scale that threatens the whole ecosystem.

Sea Shepherd spent more than a decade in Antarctic waters confronting the illegal Japanese whaling fleet, a campaign that ended in victory. The threat has changed. Where harpoons once decimated whale populations, krill supertrawlers now take the food those recovering whales depend on.

The fleets work the same waters where humpbacks and fin whales feed, competing with them for the same prey. In 2025 a humpback was confirmed killed in a krill net, and sea ice loss is squeezing krill from the other side.

The catch limitThe fishery closes for the season when catches reach 620,000 tonnes. The fleet hit that mark early for the first time on August 1, 2025, and again on August 12, 2026.

Gerlache Strait

One of the most important whale feeding areas in the Southern Ocean. Proposed protections have faced repeated opposition at international bodies.

Active front · Scotia Sea

South Orkney Islands

A marine protected area lies here, and the krill fleet concentrates in the feeding grounds just outside it where whales and seabirds forage.

Sea Shepherd / Krill

What Depends on Krill

  1. 01

    Whales

    Humpback, blue, minke and right whales feed on krill swarms to fuel their migrations and raise their calves.

  2. 02

    Penguins

    Adelie, chinstrap and emperor penguins forage close to their colonies, right where the trawlers work.

  3. 03

    Seabirds

    Albatrosses and petrels depend on krill directly and on the fish and squid that eat it.

  4. 04

    Seals, squid and fish

    Remove krill and the food web does not just lose a link. It loses its foundation.

Sea Shepherd / The Toll

A Toll on Wildlife

When krill is taken close to breeding grounds, the animals that depend on it are the first to pay.

Antarctic fur seals

57%

fewer adults since 1999, down from about 2.2 million to 944,000. Mothers now travel too far from breeding beaches to find food. Listed as Endangered in 2026.

Emperor penguins

3years

of near-total breeding failure at the second largest emperor penguin colony on Earth.

Southern right whales

23%

decline in the body condition of mothers over three decades, leaving less energy to raise healthy calves.

Sea Shepherd / The Fleet

The Supertrawlers

Krill supertrawlers are floating factories built to catch as much krill as physically possible, flagged to a handful of nations and fitted with trawl nets that capture vast quantities at once.

Humpback whales were dragged down and killed in these nets in 2021 and 2022, and another whale died in a krill net in 2025. Norwegian and Chinese vessels now take nearly nine of every ten tonnes.

Sea Shepherd / The Threat

What Threatens It

  1. 01

    Industrial extraction

    Hundreds of thousands of tonnes a year come out of the same feeding grounds used by whales, penguins, seals and seabirds.

  2. 02

    Whales killed in nets

    Trawls work in active feeding areas. The true toll in these remote waters is likely higher than what gets reported.

  3. 03

    A warming ocean

    Sea ice loss is already shrinking krill habitat. Industrial fishing on top of it is a squeeze krill cannot absorb forever.

  4. 04

    Transfers at sea

    Fleets refuel and offload at sea, staying on the grounds longer with less oversight.

  5. 05

    Blocked protections

    Protected areas for key feeding grounds keep getting blocked by nations with krill interests, and in 2025 no new limits were agreed.

  6. 06

    Consumer demand

    The fishery exists because there is a market. Every krill oil supplement and krill-based feed keeps the trawlers working.

Sea Shepherd / On the Water

What Our Crews Do

While the fleets work the feeding grounds, our crews are in the same waters, documenting, researching and building the case for protection.

Fleet documentation

Tracking, photographing and filming trawlers in whale feeding grounds to build the record for policy change.

Whale research

Scientists from Stanford, UC Santa Cruz and the University of Pretoria sailed in 2026, identifying whales by photo across the study area.

Working together

Sea Shepherd groups in Germany, Switzerland and beyond join forces for the largest combined Antarctic campaign to date.

Policy and retail pressure

Evidence from the water goes to international bodies and to the companies still selling krill products.

Sea Shepherd / Results

Building the Case

Four seasons of evidence from the Southern Ocean, and retailers are starting to listen.

  1. 2023 to 2026 Allankay

    4seasons

    in Antarctic waters documenting the krill fleet, from the Peninsula to the South Orkney Islands.

  2. 2025 CCAMLR

    624,918t

    of krill caught, the most ever recorded, closing the fishery early for the first time.

  3. 2026 South Orkneys

    1,000

    whales counted in a single feeding group by scientists aboard the Allankay.

  4. 2026 RetailNow

    80%+

    of German drugstores have dropped krill products, and Australia's two largest supermarkets have too. Our 2025 documentation helped persuade Holland & Barrett to stop selling krill.

Sea Shepherd / Take Action

Stand Up for Krill

Two ways to fight back, whether you shop for krill products or sell them.

For individuals

Tell a retailer to drop krill

Find a store near you that still sells krill and send its team a letter in seconds. Every message shows retailers their customers are watching.

For companies

Take the Antarctic Krill Pledge

If your business sells supplements, pet food or omega-3 products, commit to keeping krill-derived ingredients off your shelves.
