Our Goals

  1. Acquire and make easily accessible to zoo and aquarium professionals the current body of knowledge on animal welfare and ethics.
  2. Conduct and facilitate welfare assessments and applied welfare research on captive exotic animals.
  3. Convene important discussions and presentations on captive exotic animal welfare and ethics.
  4. Train professionals on captive exotic animal welfare best practices and policies.
  5. Recognize advances in improving captive exotic animal welfare and ethics through awards.
