<div class="abstract-group "><div class="article-section__content en main"><p>We compared three methods of boat driving and pedal operation using 600-s transects: these were the parallel continuous (PC), parallel intermittent (PI), and arc-intermittent (AI) methods for surveying warmwater fishes in reservoirs. We tested differences in total time and distance per transect, CPUE (fish/h, fish/m), and length frequencies of captured fish among methods. The PC method took the least amount of time, while the AI method took the least amount of distance to complete a transect. The AI method provided slightly higher CPUE (fish/h, fish/m) for Bluegill<span> </span><i>Lepomis macrochirus</i><span> </span>and Yellow Bass<span> </span><i>Morone mississippiensis</i><span> </span>and higher CPUE (fish/m) for Common Carp<span> </span><i>Cyprinus carpio</i>, Green Sunfish<span> </span><i>L. cyanellus</i>, and Largemouth Bass<span> </span><i>Micropterus salmoides</i>. Each method caught similar size ranges of fish; however, there were slight differences in proportions of sizes for Gizzard Shad<span> </span><i>Dorosoma cepedianum</i>, Largemouth Bass, and Bluegill. Overall, the AI method performed slightly better for a few species; however, difference in the methods were minor. Any technique should work well for monitoring reservoir fish populations when fish/h is the effort metric.</p></div></div>
