Abstract: | We investigated the effect of salinity on growth, survival, and condition of pinfish Lagodon rhomboides juveniles (36–80 mm standard length) in two laboratory experiments in July 2003 and June/July 2004. Our results show that
juvenile pinfish grown in laboratory conditions under a range of salinities experience rapid growth and high survival in typical
estuarine-like salinities (15–30 ppt). We also found that relative weight as an index of condition corroborates the idea that
pinfish are well adapted to survive and grow in a wide range of salinities. Such rapid growth and high survival in a dynamic
environment may afford juvenile pinfish potential ecological advantages over other estuarine-dependent fish species that are
relatively more constrained by changes in salinity regime. Because coastal development is wide-spread throughout Gulf of Mexico
and Atlantic estuaries, insights concerning the impacts of human-induced changes to estuarine environments are essential for
effective management practices. |
