Techniques for Aquatic Organism Capture

Chloe Spangler discusses various capture techniques for the eastern hellbender salamander, including stream nets, wading and turning, skin diving, and electroshocking. Each method's pros and cons are evaluated, with a recommendation to combine wading and skin diving for effective and less harmful capture. References are provided for further reading.
