Evidence-based analysis of striped bass mortality, conservation, and fisheries management
The 13.16 Million Fish Discovery
For nearly three decades, striped bass release mortality was estimated at 9% based on a 1996 study with significant limitations. Modern telemetry research tracking over 8,000 fish reveals the actual rate is approximately 4.5%, half of what management assumed.
Using ASMFC's own data from 2014-2024, this discrepancy represents 13.16 million fish counted as dead that actually survived. These phantom fish shaped stock assessments, justified restrictive regulations, and penalized recreational anglers based on false premises.
