Post‐spawn movements and habitat use by greater redhorse, Moxostoma valenciennesi

摘要: A combination of radio telemetry and surface observations were used to characterize the movements habitats greater redhor- se, Moxostoma valenciennesi, after spawning in Grand River, Ontario, Canada. This river supports a large population redhorse that migrate upstream spring spawn on riffles. After spawning, moved as far 15.2 km downstream areas maintained summer home ranges low velocity runs. Mean (tSE) water depth by was 46.3t0.9 cm, velo- cities less than 5 cm/s. Greater usually located over cobble/gravel substrates covered with Cladophora. Although interspecific associations golden redhorse, M. erythrurum, common carp, Cyprinus carpio, smallmouth bass, Micropterus dolomieu, northern hog sucker, Hypentelium nigricans, observed, most associated conspecifics. Areas habitat types throughout did not change, until relocation overwintering occurred early autumn. Un resumen en espaiiol se incluye detras del texto principal de este articulo.
