I can't say I've noticed a difference one way or the other. I'm just happy when they get actual fish, and not all the other stuff (like the umpteen lemons, violins, vampire books and so on). I usually don't go fishing with more than 2 sims, and they would both be fishing in the same area, if not at the same spot.
Maybe this needs some testing. 10 minutes watching and 10 minutes NOT watching, count the catches, and see if there is a difference.
I'm not sure either. I have left Sims fishing to check on the rest of the family and I get notices of the fish that are caught. Can't say whether or not it's more or less. It's just hard to watch them doing so. Kinda as exciting as watching paint dry …
