How the UK Contributes to Global Conservation Efforts for Migratory Shark Species
The UK, with its rich marine biodiversity and strategic location, plays a significant role in global conservation efforts, particularly for migratory shark species. Here, we delve into the various initiatives, research, and policies that underscore the UK’s commitment to protecting these vital marine predators.
Understanding the Threats to Shark Populations
Before diving into the UK’s conservation efforts, it’s crucial to understand the threats facing shark populations globally. Sharks, including migratory species like the blue shark (Prionace glauca) and the whale shark (Rhincodon typus), are under severe pressure due to overfishing, habitat loss, and climate change.

- Overfishing: Industrialized fishing has led to a dramatic decline in marine predatory fish biomass, including sharks. Many shark species are caught accidentally in fishing gear intended for other species, a phenomenon known as bycatch.
- Habitat Loss: Critical habitat areas for sharks are being destroyed or degraded, further threatening their survival.
- Climate Change: Climate impacts are altering the distribution and abundance of shark prey, making it harder for sharks to survive.
UK’s Marine Conservation Framework
The UK has a robust framework for marine conservation, which includes several key components:
Special Areas of Conservation (SACs)
The UK has established a network of Special Areas of Conservation (SACs) under the Habitats Directive. These areas are crucial for safeguarding species and habitats, including those of migratory shark species. For example, the Cardigan Bay SAC in Wales is a vital habitat for smallspotted catsharks (Scyliorhinus canicula) and nursehounds (S. stellaris), and research here has highlighted the importance of temporal niche partitioning in their coexistence.

Regional Biodiversity Action Plans
Plans like the Welsh Marine Evidence Strategy (2019-2025) and the Welsh National Marine Plan are designed to strengthen species and habitat protection. These plans incorporate restoration and recovery objectives, aligning with international programs such as the Decade of Ocean Science for Sustainable Development and the EU Biodiversity Strategy 2030.
Research and Monitoring
Baited Remote Underwater Video Stations (BRUVS)
The use of BRUVS in areas like Cardigan Bay has provided valuable insights into the spatial and temporal patterns of habitat use by sharks. This research helps in identifying critical habitat areas that need protection and informs regional management strategies.
British Antarctic Survey (BAS)
Although focused on polar ecosystems, the BAS’s research on the impacts of climate change and commercial fishing has broader implications for global marine conservation. Their work on understanding ecosystem responses to change is crucial for developing conservation and management strategies that can be applied to various marine environments, including those inhabited by migratory shark species.
International Collaboration and Policy
International Union for Conservation of Nature (IUCN)
The UK is actively involved with the IUCN, which plays a pivotal role in global conservation efforts. The IUCN Red List of Threatened Species, which includes many shark species, provides a critical framework for assessing the conservation status of these animals. The IUCN also provides technical and scientific advice to governments and international environmental treaties, influencing policy decisions that affect migratory shark species.
Convention on Migratory Species (CMS)
The UK is a signatory to the CMS, which aims to conserve migratory species across national boundaries. The CMS provides a platform for international cooperation and the development of conservation agreements, such as the Memorandum of Understanding on the Conservation of Migratory Sharks, which includes species like the blue shark and the whale shark.
Conservation Organizations and Initiatives
Shark Trust
The Shark Trust, a UK-based marine conservation charity, is dedicated to promoting the study, management, and conservation of sharks, skates, and rays. The organization advocates for legislation to regulate overfishing and the shark fin trade, and it supports the establishment of marine protected areas and shark sanctuaries.
Sea Shepherd Conservation Society
Although an international organization, Sea Shepherd has a significant presence in the UK and works to protect marine wildlife, including sharks. Their direct-action tactics help expose and confront illegal fishing activities that threaten migratory shark species.
Animal Welfare and Public Awareness
The Case of the Robot Whale Shark
A recent controversy involving a robotic whale shark in a Chinese aquarium highlights the ongoing discussion about animal welfare in captivity. While the use of a robot can be seen as unethical, it also raises important questions about the treatment of live animals in aquariums and the conservation status of species like the whale shark. This debate underscores the need for better regulation and public awareness about the welfare of marine animals in captivity.
Practical Insights and Actionable Advice
For those interested in contributing to the conservation of migratory shark species, here are some practical steps:
- Support Conservation Organizations: Donate to or volunteer with organizations like the Shark Trust and Sea Shepherd, which work tirelessly to protect shark habitats and combat illegal fishing practices.
- Raise Awareness: Educate friends and family about the plight of shark species and the importance of conservation efforts.
- Advocate for Policy Change: Contact your local representatives to support legislation that protects marine habitats and regulates the trade of shark products.
- Choose Sustainable Seafood: Opt for seafood that is certified as sustainably sourced to reduce the demand for products that contribute to overfishing.
