Wild Seagrass Fish Nursery Habitat

Seagrass meadows serve as essential nursery habitat for commercially and ecologically important fish species, and their decline has significant welfare consequences for juvenile fish populations.

Key Facts

Seagrass supports over 70 fish species including commercially important bass, seahorses and pipefish
UK has lost 92% of seagrass coverage through coastal development and water quality decline
Juvenile fish in seagrass experience dramatically lower predation rates than in open water
Carbon stored in seagrass sediments releases when beds are destroyed, contributing to climate change

Welfare Considerations

Juvenile fish deprived of seagrass nursery habitat face elevated predation pressure in unstructured habitats, leading to higher mortality and chronic stress. Seagrass restoration directly improves fish survival and reduces stress in populations of species including commercially fished bass. The ecosystem services of seagrass support the welfare of multiple species simultaneously.

What You Can Do

Support Project Seagrass and WWF seagrass restoration campaigns
Report seagrass damage from anchoring or dredging to relevant marine authorities
Reduce fertiliser runoff from gardens that increases coastal eutrophication
Choose seafood from fisheries with seagrass-friendly management practices
