The word poaching might apply in all those situations even though the law would not charge you with such.
That of course means that poaching is a "general category" of offense. My point has been all along thatpoaching is a very specific offense. Again, according to the primary useage as defined in the dictionary, it is trespassingfor the purpose of taking fish orgame.In other words to use your example it would be analogous to say grand theft, not the general term stealing. I would say the general category would be tresspassing and the type of tresspass would be for the purpose of taking fish or game or in a word, "poaching". Anyway, just my opinion. This has been an interesting discussion. Y'all take care!
