White suckers inhabit the freshwater bodies in North America. Their population is wide spread, and that's why fishing on them causes no exploitation.

People love catching them for their quality weight and tasty meat. These fishes are one of the prime food sources for people living there. Suckers can be found in shallow lake or pond waters, but they are mainly found in the flowing waters of a river or stream.

For fishing, people use worms as bait. Any worm can be used as the bait, but nightcrawlers are recognized as the prime bait when it comes to sucker fishing. Suckers can be caught at any time of the year, but spring is the best season for catching suckers.

Spring is the season when they spawn. So naturally, they keep looking for food, and that's how attracting them towards the bait becomes naturally easier.
