Trotlines usually have 10 to 25 hooks that hang from short, regularly spaced lines called trots. Trotlines allow you to catch lots of catfish quickly. The heavy nylon cords, large hooks, and big swivels used to make each line can subdue even the fattest cats. Target transition areas—where a tributary flows into the main lake, for example, or a side channel rises onto shallow flats. Tie the trotline between snags or make anchor points. Then, after baiting the hooks, add a weight in the middle to pull the line near the bottom. Chunks of oily baitfish are ideal for big blues and channel cats, while flatheads prefer live bluegills and suckers. Work with a buddy. Both anglers should carefully grip the main line and pull their way along it, removing fish and rebaiting.
