Population Dynamics of a Migration Limited Shortnose Sturgeon Population
Upstream migration of the Cooper River, South Carolina, population of shortnose sturgeon (Acipenser brevirostrum) is severely limited at Pinopolis Dam (river km 77). Shortnose sturgeon congregating and spawning in the tailrace of the dam has been documented but data is lacking on the group's population dynamics. From 1995 through 1999, the population was sampled in the tailrace with 91.4 m long bottom-set gillnets during the spawning season when fish were concentrated in the area.
