Spawning migration distance was related to body condition and size-at-age/maturity in Atlantic cod {Gadiis morhua; Jorgensen et al. 2008), where fish that migrated longer distances were generally older, bigger fish with higher overall fitness. Although the relationship between barred sand bass TL and spawning migration distance was somewhat inconclusive, we cannot rule out bioenergetics as a possible explanation for individual variability in migration distance, as maturity and fitness were not determined for tagged fish. Migration distance also varied by peak spawning season tagging location. This could be due to variability in the numbers of returns across sites or distinct differences among sites. Nemeth et al. (2007) attributed differences in migration distance and functional migration area (, the area inclusive of home ranges and spawning ground) to differences in shelf area and fish length between spawning sites, where the site demonstrating a smaller functional migration area and shorter migration distances contained a smaller shelf area and aggregations of smaller fish. Spawning Season Residency Barred sand bass return rates at Huntington Flats suggested a spawning residence time within a 7 to 35-day period. Nemeth et al. (2007) reported a similar spawning residency period for tagged red hind recaptured on their spawning grounds (, 7 d-2 mo); however, diver s
