Sea Shepherd

We fight to defend, conserve and protect the ocean

#SeaShepherdMeeresschutzBalticSeaSeegras

Sea Shepherd is an international nonprofit organization dedicated to protecting biodiversity and marine ecosystems.

What drives Sea Shepherd Global

We use methods such as direct action to investigate, document, and stop illegal activities at sea and on land.

In Germany, we focus on protecting the Baltic Sea, which is one of the world’s most endangered marine regions.

Baltic Sea Campaign

Every year from June through October, we patrol the waters between Flensburg and Rügen, as well as around Bornholm, aboard our ship TRITON. During these patrols, we document violations of conservation laws, recover ghost nets, and organize cleanups along the coast. Since 2021, we have recovered over 30 metric tons of old fishing gear from the Baltic Sea, including nets, towing gear, lines, and other fishing equipment.

Off the Danish island of Bornholm, the crew of the BALTIC SEA CAMPAIGN 2026 set a new record: they recovered the largest ghost net that Sea Shepherd has ever retrieved from the Baltic Sea. It weighed 1,867 kilograms.

Marine Meadows

In 2023, we launched the annual MARINE MEADOWS campaign in collaboration with GEOMAR Helmholtz Center for Ocean Research Kiel. The goal is to restore seagrass meadows in the Baltic Sea. To achieve this, we rely on citizen science: We train organizations and individuals and actively involve them in the effort. This approach is intended to accelerate the restoration of seagrass meadows and expand it to cover larger areas.

The campaign was once again extremely successful in 2026: A total of 62,633 seagrass plants were replanted, restoring an area of over 7,000 m²—roughly the size of a soccer field.

Particularly noteworthy: Several areas that were planted as recently as 2025 have now reached a density of more than 100 plants per m². The highest measured density is 153 plants per m². Originally, eight plants per m² were planted there. That represents an increase of about 1,815% within a single year!

What Sea Shepherd Global has going on

Both campaigns will continue in 2027. The TRITON will once again be deployed in the Baltic Sea, and the seagrass restoration project will enter another season. Even outside the planting season, the restored areas will be monitored regularly to scientifically observe and document their development.

In addition, Sea Shepherd Global carries out numerous international campaigns, including one in Antarctica against the growing krill fishery, which is increasingly threatening the Antarctic ecosystem.

How to become active with Sea Shepherd Global

There are various ways to get involved with Sea Shepherd and participate in national or international campaigns. And if you’d rather not go out on a ship, you can also support the organization by helping with numerous cleanups and tasks on land. Even just one less meal of fish is a valuable contribution to protecting our oceans.
