I don't like the bag for several reasons. First, if you catch too many fish, they can quickly become overcrowded in a bag, in a pond with no quick aeration. You are forced to move fish quickly. I don't care for that. Next, I don't always pull the seine equally, side to side. With a bag, you must pull the seine toward the bag. If you have fish of different sizes, or different species, the big ones beat up the small ones. I like to allow them room to move and separate according to size. Bruce, you noticed how the fish separated themselves in the seine? You can't work them as well in a bag. Bags, to me, are for big numbers of big fish to be handled in a big way, fast. You saw what happened when we took our time.
Teach a man to grow fish... He can teach to catch fish...
