Movement patterns of juvenile sandbar sharks (Carcharhinus plumbeus) on their nursery grounds were investigated by using acoustic telemetry to actively track shark.\u00a0\u00a0Twenty five sharks were fitted with transmitters and their movements continuously monitored for periods of between 6 and 72 h.\u00a0\u00a0Tracked sharks spent the majority of their time moving parallel to the coastline, predominately within 3 km of shore and at depths between 2 and 5 m.\u00a0Although there was a core area of activity near the Delaware coast near the entrance of the bay, several sharks ranged farther from shore and two sharks crossed from one side of the bay to the other.\u00a0\u00a0Movements of sharks were heavily influenced by tidal currents, but there were no apparent trends associated with depth or time of day.\u00a0Sharks tended to swim against the tidal current, presumably to limit the distance they are transported by the strong currents and to increase the amount of time spent in optimal nursery habitat.\u00a0\u00a0The results of this study indicate that juvenile sandbar sharks typically move within a restricted area in shallow water, fairly close to shore withinDelaware Bay\u00a0.\u00a0\u00a0However, these sharks are capable of making long distance movements within the bay in short time periods.<\/p>\n
