摘要: Abstract We used mark–recapture techniques to examine the effects of four types road crossings on fish movement during spring base flows and summer low in small streams Ouachita Mountains, west-central Arkansas. assessed for 21 species seven families through culvert, slab, open-box, ford natural reaches. detected no seasonal or directional bias any crossing type Overall was an order magnitude lower culverts than other reaches, except slab crossing. In contrast, open-box showed little difference from reaches overall fishes. Numbers that traversed within three dominant (Centrarchidae, Cyprinidae, Fundulidae) also were reduced at relative sprin...
