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 coastal bayou (Davis Bayou). All three of these populations have potential access to coastal waterways. In this study, scientists have determined the effects of salinity on survival, growth and reproduction of Nile tilapia from Mississippi to assist in predicting their potential spread to estuarine and coastal regions.
