Anybody got any fishing recommendations?

So in shtf there would be a need to disguise these floats, do these gill nets knot up easy, does it take more than one person to place net, and pull net, are they worth the effort, dragging around giant nets and spending x amount of time setting up is it really smart thing to do?

What size are your nets I have been looking at these since jd1 made the comment I am interested in them, but so far they all look to be for sea use, which is of no use to me the fish where I live would swim through them.
