The Act applied only to protected animals from halfway through their gestation or incubation periods (for mammals, birds and reptiles) or from when they became capable of independent feeding (for fish, amphibians and, the common octopuses).

The project must also pass an ethical review panel which aims to decide if the potential benefits outweigh any suffering for the animals involved. ASPA involves three levels of regulation — person, project, and place. The 'person' level is achieved by the granting of a "personal licence" (PIL, procedure personal licence) to a researcher wishing to carry out regulated procedures on a protected animal. Having undergone a defined sequence of training, a researcher can apply for a PIL permitting specified techniques to be carried out on named species of animals. The 'project' level
