Holy cow, I just found some fishing laws in New Brunswick Canada. Strict is an understatement:
Angling is the only legal method of catching sport fish.
* Jigging is illegal. You cannot have a jigging device or spear within 15 metres of the water. If you hook a fish accidentally in any part of its body except the mouth, you must release it immediately.
* You cannot use a gaff or spear to land a sport fish.
* You cannot have a snare or bow and arrow within 15 metres of our rivers, lakes and streams unless you are hunting or trapping.
* You cannot fish with more than one line. (No more than three hooks attached)
* You cannot use a setline in our rivers, lakes and streams except for ice fishing.
* You cannot fish for Atlantic salmon with an artificial fly that has more than two hooks.
* You cannot fish at night. (See angling hours.)
* You cannot fish with an artificial light or light from a fire.
* You cannot purchase, sell or barter sport fish. (This does not apply to licensed aquaculture facilities.)
* You cannot fish from a bridge.
* You cannot fish within 22.8 metres (25 yards) of the lower entrance to a fishway or dam.
In America I think we have one rule: no dynamite in a school zone 😀
