I'm not certain if it's in their genes, but nightcrawlers are absolutely a must if you are trying new ground. Therefore, in other words, if you are visiting a new place: nightcrawlers are a must! This month of August, almost all the posts here will show fish caught on NIGHTCRAWLERS. I'll focus on its importance, as well as its reliability. Well...I'll call this the "worm month" (Original name, huh?).
Yesterday my focus was directly on the white perch. I usually cast out with an 1 oz weight (it's enough for me, even though some people use 2-3oz there), past the first pillar of the bridge; and 15lb or less of line (yesterday I was using 14lb fluorocarbon). The perch don't really get big at the Schuykill River (the biggest one, rarely, pass the size of a palm of a hand), but the action is constant and steady. I did my homework, and I came to observe and learn that schools of white perch pass through that location every ten minutes or so. Therefore, if there are breaks, they don't exceed the ten minutes limit (usually). Of course there will be days that the fishing is really bad (due to a number of factors - weather and temperature being some of them), and on those days no perch will bite at all. Don't give up: just come another day.
