The main objective of this project was to examine the potential use of pheromones as a method of controlling Pacifastacus leniusculus. The main subjects examined as potential control mechanisms were sex pheromones, predator odours (as well as crayfish stress and alarm odours), feeding stimulants and deterrents, and cannibalism-inducing compounds. Pheromone trials were conducted both in the laboratory and field.
