New Breed Vets
Synopsis | Episode Guide | Australian Wildlife Hospital | Acclaim


In this special investigative episode of New Breed Vets, we delve into the world of animal forensics. Steve visits the National Wildlife and Forensics Laboratory in Ashland, USA to join the high-tech scientific fight against wildlife criminals. In Australia, we probe the mysterious deaths of koalas in an isolated island colony. And in England, we join New Breed Vets investigating the cause of suspicious mouth lesions that could prove serious for a gorgeous Lowland Gorilla.

Episode: “Forensics”
Case Study: Short-nosed Sturgeon Sterilisation
Location: University of Georgia, Athens USA
Veterinarian: Dr Stephen Hernandez-Divers

Dr Hernandez-Divers from the University of Georgia is working with the US Fisheries and Wildlife Service on an endangered species program with Short-nosed Sturgeon fish. The joint project involves delicate birth control surgery on captive-bred individuals. To save the species from extinction, US Fisheries are releasing captive-bred sterilised fish into wild populations to ascertain habitat viability, adult mortality rates and distribution, while maintaining the integrity of the wild population gene pool. This fish was anaesthetised by simply adding anaesthetic to its water. Once unconscious, Dr Hernandez-Divers inserted an endoscope through the outer skin of the fish. The endoscope was fitted with a small camera to allow Dr Hernandez-Divers to see precisely where he was working. The next step was to insert a small syringe and inflate the swim bladder – the organ the fish uses to control buoyancy. A second endoscope was inserted after the ovary was located. As Dr Hernandez-Divers cut the ovaries free, the incision was simultaneously cauterised to seal the wound and prevent blood loss. The whole organs were extracted in one piece through another small incision. The ovarian tubes were then tied to prevent any possibility of eggs being released. The tiny keyhole incisions were then stitched and the fish was returned to a recovery aquarium.

Case Study wolf  

Episode: “Forensics”
Case Study: Grey Wolf Autopsy
Location: National Fish and Wildlife Forensics Lab, Oregon USA
Veterinarian: Dr Richard Stroud

The National Fish and Wildlife Forensics Laboratory in Ashland, Oregon is the only facility of its type – a world-class wildlife forensics centre, with the latest high-tech crime-fighting equipment and personnel. This deceased Grey Wolf was brought in and positively identified by sampling a single strand of hair through DNA analysis comparison with the lab’s comprehensive DNA data bank. Dr Richard Stroud, the Senior Medical Examiner, took x-rays of the dead wolf which clearly showed dense bullet fragments lodged in the wolf carcass. Dr Stroud then performed a necropsy – the animal version of an autopsy, carefully reconstructing the path of the bullets and taking photographic evidence. The necropsy confirmed the wolf was killed from the bullet wounds. The bullet fragments were given to Mike Scanlan, the Senior Firearms Examiner, to identify the type of bullet and weapon used through a ballistics test and comparison. The collective evidence is then admissible in prosecution proceedings.
