Here's a quick and dirty example of the beginnings of a test that could be used to certify dipnetters as "responsible" before they can be issued a dipnet permit - just as is done for hunting licenses:
I don't represent this to be complete, or even sufficient. I just threw it together to show that this type of stuff is easy to do, and would not require much investment on anyone's part to put in place.
Hunter safety/ed courses have proven their worth and I know of no one that disputes their value overall to the sport. This same solution might cheaply solve some problems that our dipnetting activity does suffer from today.
This test is designed to be easy; it is designed that all will pass - just like what is done in hunter ed classes and tests. (So, no crowing from experienced dipnetters that you got 100% right - You were expected to! )
