When the capture of wild orcas became illegal, SeaWorld established a regimented (but not very scientific) breeding program that fails to consider orca welfare. Female whales are forced to breed around the young ages of 8 or 9, despite research that shows the average orca breeding age to be closer to 15. SeaWorld also conducts a practice of continuous breeding, constantly artificially inseminating females with ejaculate from male "studs" who are often aggressive -- or closely related to their breeding partners. As a result, many of SeaWorld's orcas are inbred, which can cause major problems for the survival and rearing of calves.
