That is what I was wondering also. You fishing for catfish, bluegill, small or large mouth bass, suckers, trout, crappie etc....Where do you live and what do you want to catch?
As Algo is asking it all depends on what you want to catch, are you after trout and salmon for the table or are you on about ctaching fish like catfish for sport.
I was thinking fish for food when the usual bait is not available such as live worms and minows. Kind of like if you had to make your bait. I love my cast net but that's really only good for sandy bottoms. One snag in winter water and you've lost your net.
