It seem like there are so many professions that become obsolete, will commercial salmon fishing eventually be one? I donít mean in the sense of being replaced by farmed salmon, but by using a more economical method of harvesting the fish, such as a fish wheel or some other form of trap at the place that they are returning to. Since salmon always return to the same location at a predictable time, it seems like there would be a much more efficient way of harvesting them commercially, especially the ones that come from hatcheries. Think of all of the labor and fuel currently being used with the current method. It seems like it would be much more efficient to harvest them using another means. Is there some reasoning why this is done the way we currently do it?
