You say WA is lax in its rules and has no enforcement. How would this change the enforcement? The recreational mining rules have been in the legislature since sometime in the 90s. That would be a decade or more in which to collect information on the what, where, good, bad.

This is one of a whole lot of activities that need an honest look at the impacts to fish.

A question that has been asked by miners "why should I be restricted from killing or injuring fish because of my recreational choice while you (F&G agencies) license people to kill those same fish commercially and recreationally." The fish is just as dead.
