Capture of Wild Animals for the Pet Trade

February 21, 2018

Position

The Canadian Veterinary Medical Association (CVMA) is opposed to the capture of wild animals to be kept or sold as pets.

Summary

  • Exploitation of wildlife is a significant threat to global biodiversity.
  • Significantly high proportions of captured wild animals for the pet trade are injured or die during capture and transportation, thereby presenting welfare and ethical concerns.
  • Capture practices may lead to extensive habitat destruction and indiscriminate injury or death of non-target species.
  • Unregulated global trade in wildlife may contribute to foreign animal diseases, zoonoses, and introduction of invasive species which can have detrimental effects on local endemic populations of native wildlife.

Background

  1. Exploitation of wildlife is a significant threat to global biodiversity (1-7).
    • Millions of vertebrate and invertebrate species are captured and traded annually, with the vast majority of this trade being unregulated and illegal.
    • Capture and removal of these animals for the pet trade often occurs in a void of knowledge with respect to each species’ population sustainability, and few initiatives exist to promote sustainability.
    • Significant numbers of these species are considered at risk of becoming endangered or extinct.
  2. Large proportions (up to 80%) of wild animals captured for the pet trade are injured or die during capture and transportation (1-10).
    • The handling and transport conditions of captured animals often present welfare and ethical concerns.
    • Animals that survive capture and transport are often unable to acclimate to captivity.
    • Wild animals manifest a range of behaviours that assist them in adapting to their natural environment. They are often instinctively afraid of humans and other domestic animals, and will not adapt to become good companion animals.
    • Information on the optimum care, behavioural needs, social structures, and nutrition of many wild animal species is not readily available. This leads to suboptimal care and premature death in captive settings.
  3. Capture of marine species may involve extensive habitat destruction and indiscriminate injury or death of many non-target species (e.g., marine tropical fish and corals) (5,11).
    • Cyanide fishing is recognized as a major factor leading to the destruction of coral reefs. This method involves squirting concentrated sodium cyanide in a focal area to stun fish making it easier to collect them. The high concentration can kill both target and non-target fish and corals.
    • Residual cyanide is believed to contribute to high delayed mortality of marine fish.
  4. Unregulated global trade in wildlife may contribute to introduction of non-native invasive species and foreign animal diseases, with potentially significant economic and public health impacts (3,12-14).
    • Little disease surveillance is conducted for legally imported non-agricultural animals.
    • The process of importation and distribution often involves keeping animals at high density and in unnatural groupings of species, providing opportunities for cross-species transmission and amplification of known and unknown pathogens.
    • The CVMA supports education of consumers about the negative impacts of exotic animal purchase.
    • The CVMA supports global efforts to combat illegal trade of wildlife through community education and capacity building with local people where these species are harvested, increased local research to better understand the effects of harvest on wild populations, and coordinated international regulations and enforcement.
