It may be needed but crashing a system is not the answer. Removing thousands of fish from any system will have negative effects anyway you slice it, hatchery or native. Recovery may happen but will likely take longer because of the sudden massive changes to the system and available nutrients.

Throwing a wrench in the system is not the answer. Steps have already been taken to monitor and help manage wild fish stocks in the mass marking that is occuring now. Do it right or suffer the possible complete crash of the entire system.
