Wild Seagrass Restoration and Fish Welfare

Seagrass meadows are critical nursery habitats for fish and invertebrates, and their restoration improves the welfare and survival of juvenile fish across temperate coastal ecosystems.

Key Facts

UK has lost 92% of its seagrass meadows over the past century
Seagrass supports around 40 fish species and stores carbon at 35 times the rate of tropical forest
WWF-led restoration trials at Pembrokeshire have successfully re-established seagrass beds
Anchoring, water quality and recreational activity remain primary threats

Welfare Considerations

Fish using seagrass as nursery habitat benefit from shelter, food and reduced predation pressure. Loss of seagrass forces juvenile fish into less protective habitats, increasing predation mortality. Improved water quality from seagrass oxygenation and filtration benefits all coastal fish welfare. Seagrass restoration directly improves fish survival and reduces stress from predation exposure.

What You Can Do

Support WWF and Project Seagrass restoration crowdfunding campaigns
Avoid anchoring on seagrass beds; use designated mooring buoys
Advocate for marine protected areas that include coastal seagrass habitat
Reduce nutrient runoff to coastal waters through gardening and farming choices
