Angel sharks are flat-bodied sharks which can grow up to 2.4m in length and are normally found submerged in sandy habitats in coastal waters. Angel sharks (Squatinidae) rank as the second most threatened family of elasmobranchs (sharks, skates and rays) in the world. Three species are found in the Eastern Atlantic and Mediterranean Sea, all listed as Critically Endangered on the IUCN Red List of Threatened Species, and are the current focus of our efforts given their threat status:
Once widespread throughout coastal areas of these regions, angel sharks have suffered steep declines throughout their historic range. Information on Sawback Angelshark and Smoothback Angelshark is severely lacking, however the Canary Islands have been identified as a unique stronghold for the Angelshark, as this species is still regularly sighted.
Since 2016, the ASCN Partners and a wide range of collaborators have focused on developing strategic conservation planning documents for angel sharks.
A number of Action Plans have been developed at different geographical scales via multidisciplinary workshops. All these documents sit underneath the Eastern Atlantic and Mediterranean Angel Shark Conservation Strategy, and aim to identify the key actions needed to overcome major threats to angel sharks in each specific region.
The ASCN actively encourages individuals or organisations across the range to get involved in delivering the Action Plans in collaboration.
If you have supplementary information about angel sharks, please complete the questionnaire.
THREATS TO ANGEL SHARKS
Provide evidence and drive legislative change
Raise awareness of the importance of the Canary Islands for Angelsharks
Develop the Angel Shark Conservation Network
Habitat and Pollution
Please help us protect Angel Sharks in the Canary Islands, East Atlantic and Mediterranean Sea by reporting your sighting to the Angel Shark Sightings Map. This information will be shared amongst the Partners and Collaborators to better understand and conserve Angel Sharks in the region.
ANGEL SHARK CONSERVATION NETWORK (ASCN)
The success of the Action Plan and Strategy is ultimately down to the individuals and organisations working together towards the common Visions.
All interested parties are invited to join the ASCN, help to deliver the objectives laid out in each document and receive updates on angel shark conservation news.
The purpose of the ASCN is to:
Facilitate dialogue and information sharing on all matters concerning angel shark conservation, including collaborative projects and joint funding opportunities.
Host an email-group to send updates, providing information on activities in progress or completed as part of the Action Plan or Strategy.
Ensure that consistent and clear messages regarding angel shark conservation is delivered to the wider community.
Encourage a core group of individuals/organisations to attend a follow-on Angel Shark Conservation Workshop in 2020
Join our multidisciplinary Angel Shark Conservation Network (ASCN) and help us to protect these Critically Endangered sharks.
Celebrate International Angel Shark Day on the 26th June every year. A day for all 22 species of angel sharks. Search #AngelSharkDay on social media to hear about work from researchers and conservationists in different regions.
The following organisations work alongside a number of individuals as part of the ASCN.
The organisations in this list will be updated quarterly with additional members.
Universidad de Las Palmas de Gran Canaria
The Universidad de Las Palmas de Gran Canaria (ULPGC) is one of the leading Spanish universities and is a leader in the use of new technologies and research related to marine and maritime areas. It is comprised of 153 research groups covering all fields of knowledge.
WWF Mediterranean Marine Initiative
Leading change for the Mediterranean Sea. By bringing together the best of WWF’s marine expertise and engaging with a variety of partners, we bring innovative approaches to marine resource management and biodiversity protection to secure a sustainable future to Mediterranean’s wildlife and people.
PROGRESS TO DATE
The Angel Shark Conservation Network (ASCN) is working with partners to deliver actions set out in the Action Plan and Strategy. Major achievements are shown below. Full details of angel shark conservation news and research are sent to the ASCN through quarterly e-bulletins.
ASP:CI research has identified one confirmed and 13 potential Angelshark nursery areas around the Canary Island archipelago, with data used to develop a Guidance Document to better protect important habitats of this Critically Endangered species.
Research led by the ASCN Partners to assess angel shark extinction risk across the Eastern Atlantic and Mediterranean Sea was published in ICES Journal of Marine Science. Results show that Sawback Angelshark range has declined by 51%, Smoothback Angelshark range by 48% and Angelshark range by 58%.
The Spanish Ministry of Ecological Transition have announced today (6th June 2019) that angel shark populations are fully protected in the Canary Islands, through inclusion in the category “in danger of extinction” on the Spanish Endangered Species List. This is of vital importance to enable continued survival of angel sharks in their unique stronghold.
The IUCN SSC Shark Specialist Group is currently undertaking a global reassessment of all sharks, rays, and chimaeras for the IUCN Red List of Threatened Species through a series of regional workshops. So far we have successfully completed 4 workshops and assessed 357 species, with plans for 7 more workshops throughout 2019/2020 to assess the full ~1,250 chondrichthyan species.
A collaborative sightings map was developed in December 2016 to have a central coordinated system to gather sightings of angel sharks across their range.
The Angel Shark Project used data collected through POSEIDON (a citizen science program to collect marine biodiversity data in the Canary Islands), to identify the distribution patterns, habitat use and population structure of the Angelshark (Squatina squatina) in its last stronghold.
The Angel Shark Project and Natural Resources Wales are asking fishers across Wales to report any accidental captures of Angelsharks and follow best practice guidance to ensure Angelsharks are safely return to the water unharmed.
