Illegal Gillnet Discovered in Tenerife Breeding Ground for Endangered Angel Sharks
Authorities in Tenerife have launched an investigation after a large illegal gillnet was discovered at Las Teresitas beach, leading to the successful rescue of a critically endangered angel shark and four stingrays.
The discovery of illegal fishing gear in protected waters has once again exposed the vulnerability of marine life in the Canary Islands. Yesterday, a swimmer at Las Teresitas beach in Santa Cruz de Tenerife found a large gillnet, estimated to be 40 to 60 meters long, resting on the seabed. The net was located about eight to ten meters deep, near the breakwater. Local police have launched an investigation into the poaching, which is believed to have taken place under the cover of darkness to avoid detection.
This incident is particularly serious because the area is a vital breeding ground for the angel shark (Squatina squatina), a critically endangered species under strict international protection. A coordinated rescue effort involving the local police, Tenerife fire department divers, the Red Cross, and wildlife experts from the La Tahonilla recovery center successfully freed one live angel shark and four common stingrays trapped in the net.
Gillnets, which are anchored to the ocean floor, are strictly banned in this part of the Tenerife coastline. Because these nets catch everything in their path, they are highly destructive and pose a direct threat to protected marine life. Authorities are concerned that this may be part of a recurring problem, highlighting a need for better surveillance of these sensitive breeding grounds. While the rescue of the five trapped animals was a success, the incident serves as a stark reminder of the urgent need to strengthen protection for the coast’s most vulnerable ecosystems.
