![]() ![]() ![]() This study was conducted to explore the effects of periodic changes of salinity on different phenotypic traits in Nile tilapia (Oreochromis niloticus) in order to find out any traits that can be expressed through compensatory growth. Salinity fluctuation is a great threat for fish as most species either do not grow well or eventually die in coastal regions where salinity changes happen regularly because of different natural calamities. Our finding indicated that only water temperature, but not salinity, is the major determinant factor governing the FF fate in the fish body. On the contrary, increasing the salinity from 5 to 15 ppt at a given temperature level produced no significant change in the PK behavior. The extents of these PK changes were similar at the two salinity levels. The result revealed that at 32☌, the elimination half-lives (t 1/2β ), time to reach the peak concentration (T max ), area under the serum concentration-time curve (AUC), and mean residence time (MRT) were significantly decreased, while the clearance relative to bioavailability (CL/F) significantly increased compared to those at 24☌. The serum concentrations were analyzed by HPLC method and the PK parameters were analyzed by a 2-compartmental model. The FF was administered at a single dose of 15 mg/kg body weight via oral gavage. Twenty-eight fish were divided into four groups and kept at one of two temperatures (24 vs. The objective of the current study was to investigate the effect of temperature and salinity concurrently on the PK of florfenicol (FF) in Nile tilapia reared in brackish water. Although the influence of each individual factor is known, the combined effect is less clear. Prudent antimicrobial use requires knowledge of pharmacokinetics (PK) in a specific fish species which in turn depends on water temperature and salinity. This is particularly important given the predicted changes in coastal landscapes due to global climate change and sea-level rise. These data are vital to predicting the invasion of non-native fishes into coastal watersheds. However, successful invasion is subject to two caveats: (1) wintertime survival depends on finding thermal refugia, and (2) reproduction is hampered in regions where salinities are $30. These integrated responses suggest that Nile tilapia can invade coastal areas beyond their point of introduction. Although fish were able to equilibrate to saline waters in warm temperatures, reproductive parameters were reduced at salinities $30. However, cold temperature (148C) reduced survival of fish in saline waters $10 and increased the incidence of disease in freshwater controls. Tilapia withstood acute transfer from fresh water up to a salinity of 20 and survived gradual transfer up to 60 at typical summertime (308C) temperatures. We hypothesised that combinations of temperature and salinity will interact to affect survival, growth, and reproduction of Nile tilapia, Oreochromis niloticus, introduced into Mississippi, USA. Salinity and temperature are environmental variables that limit the spread of many non-native fishes.
