fl.biology.usgs.gov — The African jewelfish (Hemichromis letourneuxi) has been established in canals surrounding the Miami area since the 1960s. With changes in water delivery to the park, the species has recently (2000) entered Everglades National Park and expanded its range westward through Big Cypress National Preserve. Simultaneously, African jewelfish from a 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...

wfrc.usgs.gov — Ballast water discharges are the most significant cause of aquatic biological invasions in coastal waters, including the Great Lakes. Currently, treatment of ballast water prior to discharge at the receiving port offers significant promise to help control this problem. However, development of treatment technologies is limited by lack of objective More...
