Field Setup: Seasonal Window, Fish Bait & Solar Power
• Optimal Seasonal Window (Winter to Spring)
Trapping is conducted from late winter into early spring to align with the mating season (rut) and heightened territorial movement. Natural prey scarcity during winter significantly increases bait acceptance.
• Dead Fish as Primary Bait
Dead fish provides an authentic, strong olfactory lure tailored to the wetland ecosystem of the Danube Delta. The powerful scent diffuses through dense reed beds, attracting jackals from long distances.
• Solar-Powered Electric Fence System
A multi-strand electric wire perimeter powered by a 12V battery and solar panel keeps non-target livestock (cattle) out while defining the trapping area and powering camera monitoring gear.

Behavioral Innovation: The Pear Catch System ('Sistem Pară')

• Overcoming Wild Canid Neophobia
Placing wire traps directly in open habitat triggers immediate avoidance in golden jackals due to extreme neophobia.
• Funnel Corridor & Pear Geometry
The system features a funnel entry channel that guides animals naturally into an enclosed pear-shaped outer fence area.
• Curiosity-Driven Desensitization
Jackals enter the enclosure drawn by fish scent, explore around the wire cages freely, and gradually lose fear of metal structures.
• Integrated Camera Surveillance
Solar-powered trail cameras record approach behavior, hesitation time, and entry patterns to continuously refine setup.

Equipment Evaluation: Tomahawk vs. Vevor Cage Traps
TOMAHAWK
✔ Rigid Galvanized Frame: Heavy gauge wire prevents flex under 10–14 kg animal lunges.
✔ Precision: Adjustable trigger tension avoids false trips from non-target rodents.
✔ Secure Door Lock: Anti-escape gravity lock stays closed under violent struggles.
✔ Animal Welfare Standard: Smooth interior welds minimize muzzle and dental abrasions.
VEVOR (Foldable)
✖ Portability: Lightweight and easy to carry into marshy Delta terrain.
✖ Flexibility Risk: Frame can flex or jam in mud under heavy struggles.
✖ Corrosion Sensitivity: Latches require frequent greasing in saline delta environments.

Summary & Handover to Dr. Panagiotis Azmanis
✔ Behavioral Adaptation Works:
Combining winter fish bait with the Pear Catch System overcomes jackal neophobia in wild wetlands.
✔ Equipment Quality Matters:
Rigid Tomahawk traps ensure safe, reliable retention without injury during the critical waiting window.
✔ The Next Critical Phase:
Successful live trapping is only step one — immediate, safe veterinary handling is essential for telemetry success.
