wfrc.usgs.gov — Over the past 150 years, land reclamation activities have resulted in loss of significant amounts of tidal marshes (sometimes referred to as inter-tidal wetlands, the estuarine zone that is alternately flooded and exposed) in San Francisco Bay and the Sacramento-San Joaquin Delta (Bay/Delta). Recently, in an effort to halt or reverse the decline More...

fl.biology.usgs.gov — The Nile tilapia (Oreochromis niloticus) is commonly used in aquaculture worldwide. Feral populations exist in many regions where individuals escape culture and establish in natural habitats. In Mississippi, Nile tilapia are established in at least three distinct localities (fig. 1): the lower Pascagoula and Escatawpa river drainages, and a More...

fl.biology.usgs.gov — Because the African jewelfish has a broad salinity tolerance, scientists tested how the species low-temperature tolerance varied at three salinities: freshwater (0 ppt), brackish (10 ppt) and marine (35 ppt) in the laboratory. A field experiment was then conducted to examine the survivorship of individuals when caged in several common aquatic More...
