Whale entanglement has become an issue not only to the animals but to the environment and fishing industry.
Issues concerning the health and welfare of the animal
Difficulties associated with human intervention
Methods and routes used to achieve euthanasia
Whale Entanglement and Euthanasia- DMNS
Jan Lyons, C.V.T., A.A.S., CPhT
AVMA definition of euthanasia- the use of humane techniques to induce the most rapid and painless and distress free death possible.
Criteria for euthanasia:- The cetacean is stranded- Unable to swim- Judged to have a very low likelihood of
medium to long term survival.- Demeanor- Weak respirations- Failure to refloat after 2 high tides
Excitement phase from some injectable drugs
Time for death to occur
Inexperienced personnel
Cost
Disposal of body
Public view and relations
Procedure being done improperly
Complications:
IC- intracardiac IV- intravenous IM- intramuscular IP- within the abdomen IN- intranasal Sublingual- under the tongue Intrahepatic- within the liver
Routes of Administration for injectables
Implosion Ballistics Explosive grenade Powergel Magnum Explosive Dart gun Exsanguination Spinal lance Pithing
Physical Methods
Specialized needle for delivering euthanasia solutions.
Length = 1 meter ( 39 inches) Outer diameter = 21 mm (13/16 inch) Inner diameter = 12 mm ( less than ½ inch) Tubing hooked up to a pressure sprayer Needle is custom made for the procedure
and is costly
$1000.00 for customized needle
$500.00 for combination of three sedatives◦ Generally a “cocktail”
$500.00 for KCL- Potassium Chloride
Cost can increase or decrease with the size of the animal or the number that have been stranded.
Costs for injectable method:
Sedatives: delivered prior to euthanasia
• Valium®/diazepam
• Versed®/ midazolam
• Atravet/ ® acepromazine
• Rompum®/ xylazine
• Telazol®/ tiletamine
• Ketalar ® /Ketamine®
Recommended injectable medications
Sodium Pentobarbital
◦ Major issues involved with the use of this drug
◦ Difficult to dispose of the carcass after medication has been delivered.
◦ Concentration of the medication
◦ Controlled substance- CII
Euthanasia Agents used:

◦ Action of this drug
◦ Dosage
◦ Environmental impact
◦ Route of administration
