The Effects of Stocking Density and Feeding Frequency on Aggressive and Cannibalistic Behaviors in Larval Hatchery-Reared Spotted Seatrout, <i>Cynosion nebulosus</i>
… has been identified as a possible candidate for stock enhancement. Stock enhancement is the practice of releasing hatchery-reared juveniles to increase local recruitment beyond existing levels. However, raising enough Spotted Seatrout in an intensive aquaculture system has proven difficult due to …

Environment-induced Phenotypic Plasticity in the Teeth of Hatchery and Wild Largemouth Bass, <i>Micropterus floridanus</i>
Successful stock enhancement of hatchery-reared fish depends heavily on the release of individuals able to demonstrate strong survival skills. Overall survival of fishes is a reflection of a successful blend of physiology, anatomy, and behavior. With fishes being highly phenotypically plastic, the …
