You do know that natural law dictates that you may use as much of a thing as you need for your survival?
Now if dirty hippy were netting with the intention of selling fish into commerce that sort of activity could be a trespass on your (the land-owner ....(land produces few fish by the way) ... ) right to be free from the mischief of others.
In Arizona on public land (incorrectly identified as BLM ground) you may open (and hopefully close) any gate and if stopped and asked why you are there point to a distant mountain and say that you are on your way there to examine it more closely.
