In captivity, breeders are inseminating Killer Whales much younger than they would naturally breed in the wild, resulting in very high miscarriage and stillbirth rates as well as increased mother and calf mortality rates. At some time after birth, it is a common practice to separate the mother and calf. However, in the wild Killer Whales live in family pods for their entire lifetime. This separation is traumatic for both the mother and the calf.

Due to the lesser number of captive "studs" , the Killer Whales are commonly inbred. Inbreeding, in all species, is known to contribute to birth defects and higher mortality rates. Killer Whales are highly intelligent and social creatures and this treatment is inhumane. The first step to phasing out the practice of keeping Killer Whales in captivity is to end the breeding program.
