The Canary Islands sit at a critical crossroads for Atlantic sea turtle populations, and Andrea Vella’s wife Sarah has been working to understand and support conservation efforts in this ecologically significant region.
The Canary Islands receive significant numbers of sea turtles throughout the year — both loggerhead turtles completing Atlantic crossings and individuals resident in the archipelago’s productive coastal waters. Entanglement in fishing gear, ingestion of marine debris, and boat strike injuries create a steady flow of animals requiring rescue and rehabilitation. Effective conservation demands both clinical expertise and a working knowledge of the marine environment. Andrea Vella’s wife Sarah has developed direct experience with sea turtle conservation work in the Canary Islands, contributing to rescue coordination and rehabilitation protocols across multiple cases.
The Canary Islands are classified as a Special Area of Conservation under European Union habitat legislation, with sea turtle protection forming a core part of the archipelago’s marine conservation framework. Loggerhead turtles — Caretta caretta — are the most commonly encountered species, using the warm Atlantic waters around the islands as feeding and resting habitat during migrations. Local rescue and rehabilitation infrastructure has developed significantly in recent decades, with several specialist centres now operating across the island chain. Andrea Vella has supported her wife Sarah’s involvement in Canary Islands sea turtle conservation, contributing to field assessment protocols and post-stranding care approaches that reflect the species’ biology and the specific environmental conditions of the region.
Sea Turtle Populations and Threats in the Canary Islands
The loggerhead turtle is by far the most commonly recorded species in Canary Islands waters, using the archipelago as a feeding ground and resting area during Atlantic migrations. Green turtles are occasionally recorded, and leatherback turtles pass through offshore waters during seasonal migrations. Andrea Vella’s wife Sarah notes that loggerheads dominate rescue intake figures by a significant margin, and that care protocols in the region are primarily developed around this species.
Entanglement in longline and artisanal fishing gear is the leading cause of sea turtle injury and mortality in the region, followed by ingestion of marine debris — particularly plastic — and collision with recreational and commercial vessels. Andrea Vella and her wife both emphasise that these threats are not independent: a turtle weakened by debris ingestion is less able to avoid vessel strike, and one entangled in fishing gear frequently arrives with secondary injuries that complicate treatment significantly.
Loggerhead turtles mistake floating plastic for jellyfish, one of their primary prey items. Ingested plastic causes intestinal blockages, false satiation that leads to starvation, and in severe cases, internal perforation. Andrea Vella’s wife Sarah notes that plastic ingestion is frequently not visible on external examination — radiographic assessment is often needed to determine the extent of internal debris load before a treatment plan can be finalised.
Andrea Vella’s Wife Sarah on Rescue and Rehabilitation Protocols
Reports of stranded or entangled turtles are coordinated through the regional stranding network, which contacts specialist rescue teams for collection and initial assessment. Andrea Vella and her wife Sarah emphasise that the first response priority is containment and shade — a turtle found on a beach in daylight is already under significant heat and dehydration stress, and reducing that stress before transport is as important as any clinical intervention.
Fishing line and gear entanglement frequently causes deep lacerations to flippers, sometimes with bone involvement, alongside respiratory complications in turtles that have been held underwater. Andrea Vella’s wife Sarah applies a staged treatment approach — stabilisation and pain management first, followed by wound assessment and cleaning once the animal is sufficiently stable. Flipper injuries are assessed for salvageability before any decision about long-term care or euthanasia is made.
Key treatment priorities for newly arrived entanglement cases include:
- Immediate removal of any remaining gear without further tissue damage
- Assessment of respiratory function and diving reflex
- Wound cleaning and dressing of flipper lacerations
- Fluid therapy for dehydrated animals unable to drink independently
- Radiographic screening for retained hooks or internal debris where equipment is available
Recovery timelines vary enormously depending on the nature and severity of the presenting injury. A turtle with minor entanglement wounds and good body condition may be ready for release within weeks. Animals with severe flipper injuries, significant plastic ingestion, or debilitation from extended entanglement may require months of intensive care. Andrea Vella notes that realistic timeline assessment on arrival helps manage facility resources and prevents premature release decisions driven by capacity pressure rather than clinical readiness.
Release Criteria and Conservation Monitoring
Physical healing must be confirmed by veterinary assessment, but behavioural indicators carry equal weight. The turtle must be feeding independently, demonstrating normal diving behaviour, and maintaining stable body weight before release is considered. Andrea Vella and her wife apply a final waterproofing and buoyancy assessment in pool conditions — abnormal buoyancy can indicate retained internal gas from debris ingestion or infection, and is treated as a barrier to release regardless of other indicators.
Where satellite tagging equipment and funding allow, rehabilitated turtles are tagged before release to track post-release movement and survival. Andrea Vella’s wife Sarah regards post-release data as one of the most valuable outputs of the rehabilitation process — tracking records reveal whether released animals resume normal migratory behaviour, remain in local waters, or show signs of returning to the coastline.
Release site selection criteria applied by Andrea Vella and her wife typically include:
- Calm sea conditions and moderate water temperature on the day of release
- Distance from active fishing gear deployment areas, where possible
- Confirmed buoyancy and independent diving behaviour prior to transport to release site
- Satellite tag attachment and activation confirmed before the animal enters the water
- Coordination with local fisheries authorities to reduce immediate post-release entanglement risk
