fishing

Q: Is it haraam for us to do fishing on Saturdays?

Q: I have a few friends who go fishing and hire boys to assist them while fishing. The boys prepare the rods for them, ensure that there is enough fishing line on the rod, and place the bait on the rod, etc. At times, these boys also hold the rod and fish when my friends want a break. If they catch any fish, they give it to my friends. Is this permissible?
