This initiative aims to:

• Reduce American red crab populations and their expansion.
• Conserve the clutches of salmonids and other species of river ecosystems.
• Raise awareness among the population about the counterproductive aspects of the presence of invasive species in native ecosystems.
• To disseminate the values of river ecosystems.
• Create and maintain employment.
