During this putative northward migration, Cobias enter high salinity bays and estuaries, including Port Royal Sound and St.
(1)), and only recently has research verified the reproductive function of these aggregations through documentation of the presence of eggs, newly hatched Cobia larvae and reproductively mature females within the Port Royal Sound and St.
Broodstock used for the production of all stocked fish was collected from the Port Royal Sound estuary (Fig.
Samples collected from the Port Royal Sound and St.
Parentage analysis of 341 samples identified two fish in the SC 2008 collections that were both originally stocked in 2004 into Port Royal Sound. On the basis of otolith aging, 174 fish from the 2004 year class (YC) were present in the SC 2008 collections.
From the 2009 collections (n=232), 11 stocked fish were identified, all from the 2007 YC small juvenile stockings in Port Royal Sound. Thirteen 2007 YC fish were identified in the 2009 collections, resulting in an 84.6% contribution of stocked fish to the SC Cobia 2007 YC and a 4.7% contribution to the overall SC population of sampled Cobias.
The detection of stocked fish from multiple year classes of fish released within the Port Royal Sound estuary was somewhat unexpected given the many unknowns regarding Cobia life history (e.g., their use of juvenile habitat, their home ranges, movement patterns, and spawning migrations).
