The copper uptake and toxicity of young and market-size tilapia, Oreochromis niloticus, exposed to copper sulP'hate were investigated. A series of preliminary experiments were conducted to provide requisite information for the final experiment. Preliminary experiments establishe…
The dynamic nature of aquatic ecosystems requires extensive data to facilitate sustainable management practices but the resources to collect these data are often limited. Historical tensions between stakeholders in the fisheries management process have limited the potential for …
Shortnose (Lepisosteus platostomus), spotted (L. oculatus), and longnose gars (L. osseus) were sampled during the months of April–December in three tributaries of the Middle Mississippi River (MMR) to elucidate and compare critical aspects of their life history. Analyses were pe…
