Captured animals are subjected to stress than can have adverse effects on their physilogical condition. Death can sometimes occur
Muscles may be damaged if too much lactic acid builds up.
Do this:
1)Animals should be captured and handled in ways to minimize stress
2)Animals shouls not be confined to tight spaces or bound
3)Blindfolds should be used to calm animals
4)Keep animals cool
5)Avoid making excesive noise
6)move animals in corrals slowly and gently
7)Work quickly, thereby limiting handling time |

Snap traps
Used to capture small mammals in situations where live-capture is not required (pop index, species composition, experimental removals). Baited /w peanut butter or oatmeal.
Conibear traps (furbearers ... weasels, marten, fishers... set in wooden cubby with bait at back of box) |
|
|
Term
|
Definition
Can be used to capture small to medium size mammals and birds. Commercially-made traps are available for mammals of mouse, squirrel, or racoon size. Baited cage traps are used to capture ducks and other birds.
Large cage traps known as Clover traps are successfully used to capture deer, sheep, and goats. Culvert traps (large cage on wheels towed by vehicle) are used to capture bears, particularly problem bears with are acclimated to human-made structures.
National Live Trap: one end opens
Havahart Trap: two ends open.. can see through other side
Barrel/culver trap cylinder with sliding guillotine door |

Term
|
Definition
Essentially a large cage trap for capturing several large ungulates at once (elk, sheep, pronghorn). The gate is usualy designed to be closed by a concealed observer from a distance (electrical or radio signal). Once the animals learn to make regular use of the bait in the corral, a one-way gate can be installed which allows the animals to enter but not leave. |

for bears, the leg-holding Aldrich snare is often used. Leg snares have been used to live capture lynx and coyotes. Neck snares with closure stoppers can be used to live capture mammals.

Used to carry and inject drugs into animals.
Syringe to blow and dart guns.
Cap-Chur Syringes: 2.5" = 3cc
4" = 7cc
7/5" = 15ccc
Syringe: most basic delivery system. Requires close proximity. Do not inject into major blood vessel.
Jab Stick: syrince attached to a pole aand used to inject an animal caught in a trap.
Blow Guns: little bruising. Dart self injects. Close range. (Blow guns are restricted weapons in can)
Bow and Arrow: similar to blow guns. Increased distance.
Tranquilliser gun: Propels a dart containing the drug (propelled by powder charge, compresed air, or CO2). Injected by second powder charge.
Animals must be within 75m. Helicopters commonly used. Can serioulsy injure or kill an animal if dart does not hit major muscle mass. Rarely used on animals smaller than deer.
Baits: drug treated baits are used to capture waterfowl and other birds. No control over dosage rate. |

Ketamine and Rompun
-Central nervous system anaesthetic and tranquilizer which are mixed together to immobilize wild mammals.
-Reasonably cheap and easy to obtain, safe to use
-Induction time is 5 mins but recover is long (2-4 hours)
Etorphine Hydrochloride
CNS anaesthetic. 5 min induction time, and antidote is used to reverse effects.
Underdose can result in a prolonged state of excitation and death due to stress (myopathy).
Extremely dangerous to humans (prick of needle cause death)
Telazol
A new, not widely tested but seemingly great drug.
1)more predictable in effects.. induction and recovery are not variable
2)Shorter induction time which reduces stress
3)Telazol has a very wide safety margin for dosage. A mild overdose has little effect on period of anaesthesia.
4)Very seldom causes congvulsions
5)Does not affect thermoregulatory ability of animal
6)Demonstrated to have an extremely low mortality rate
7)5 times more potent that Ketamine/Rompus. Large animals done with single dart.
Has been widely used on wolves and lynx |

Receiver Placement and Options |
|
Definition
1)Ground Mobile (hand held or truck mounted. Uses triangulation method
2)Ground towers (above trees... reduces signal bounce)
3)Fixed wing aircraft (directional antennae mounted on each strut point to either side. Can switch from wing to wing. High cost and low precision.
4)Helicopter - better but very high cost
4)Satellite. Only for large, far-ranging species (polar bears, whales) very very expensive, accuracy to one km.
OPTIONS
1)scanner- scans through pre-programmed frequencies and user stops when signal is heard
2)Signal meter - electronically meters the direction of strongest signal |
