Every effort is made to ensure that the specimens used for dissection are obtained in a humane and ethical manner. Preserved specimens are purchased from biological supply companies that are bound by legislation that governs the sourcing of biological specimens. At Langara, the Biology Department has always minimized the number of specimens used for dissection by performing dissections in groups. This approach allows all members of the group to participate in the dissection to the extent that they feel comfortable, while still being able to learn from the experience. Students who object to dissection do not have to participate but are still required to learn the material. These students can self-identify at the beginning of the semester to discuss their specific concerns and work out appropriate accommodations with their instructor.
In one of the courses, students dissect rat and quail specimens. These animals are sourced locally from breeders that provide rats for reptile husbandry and quail for human consumption. Once these animals have been dissected in the lab, they are donated to Orphaned WildLife Rehabilitation Society (OWL) as a food source for injured owls, eagles, and other birds of prey. In this way, the animals have served a dual purpose, first as an educational tool, and second, as food for animals that have been injured by human activity as part of their rehabilitation to be released back into the wild.
In a typical year, the department uses 550 total animal specimens, of which the largest groups are invertebrates (35%) and fish (33%). Non-rodent mammals are the smallest group at 2%.
