Poles and light tackle are fine for potluck fishing, but if targeting the big ones, use heavy spinning or baitcasting tackle with lines up to 20-pound test, or even light saltwater gear.

Fishing is best in flowing streams, concentrating on deep holes during the day.
In canals and lakes, try areas where creeks or other flowing water comes in. Light blue or gray on top, silvery below, with many black spots. The tail is forked. Big fish often are almost black. Anywhere from 4 or 5 inches to 40 or 50 pounds.
