Fish Movement in a Large Navigation River System
Fish movement is an important ecological component to the any lotic ecosystem. The Ohio River was once a large free-flowing system, but since the early 1880s this large river system has been altered to its current state of navigation pools and tailwater reaches. To determine movement of highly migratory fish species, a study was conducted on sauger, hybrid striped bass, and paddlefish to ascertain movement patterns and the influence of riverine conditions. Fish were inserted with either t-bar anchor tags (sauger and hybrid striped bass) or coded wire tags with elastomer marks (paddlefish...
