The MSA expended a significant amount of personnel, equipment, and over $150,000 toward this project. Be sure to read "Estimating consumption rate of Atlantic Salmon smolts by Striped Bass in the Miramichi River estuary using acoustic telemetry." 
In some years, it has been confirmed that up to 18% of the salmon smolts in the the Northwest Miramichi River are being eaten by the Striped Bass.
