Research conducted on zoo primates generates valuable conservation and behavioral knowledge but raises ethical questions about individual animal welfare. Rigorous ethics oversight ensures research benefits justify any costs.
The ethics of zoo primate research requires weighing potential benefits against costs to individual animals. Minimally invasive behavioral and cognitive research generates conservation-relevant knowledge with minimal individual welfare cost. Blood draws, fecal collection, and observational studies represent a spectrum of welfare impact that well-designed ethics review processes can evaluate appropriately. Historical invasive research on captive great apes — particularly biomedical research — caused severe individual welfare harm and has been substantially curtailed under ethical pressure. The principle that captive primates who cannot consent to research deserve the highest welfare protections is now broadly accepted in accredited institutions.
