We collected juvenile striped bass Morone saxatilis and white bass M. chrysops with various gears to evaluate size selectivity and the precision of mean catch per unit effort (CPUE). We used four types of trawls, horizontal and vertical gill nets, conventional electrofishing and electrofishing with a push net, cove rotenone, and bag seine. Trawling was ineffective for sampling juvenile striped bass (<30 cm total length) and white bass (<15 cm). Striped bass CPUE data were most precise for offshore and nearshore floating gill nets, and least precise for push‐net electrofishing. Floating gill nets also provided relatively precise CPUE estimates for white bass. There were substantial differences in the size of fishes collected by the gears, with gill nets collecting the largest juveniles.
