Summary: In this study, the effects of florfenicol (FFC) on Oreochromis niloticus juveniles were investigated. The results showed that FFC caused a reduction in feed intake, survival, and biomass, as well as abnormalities in hematological, erythrocytic, and serum biochemical indices. However, most of the measured parameters and histopathological changes recovered within 3 weeks after the suspension of FFC dosing, indicating that the therapeutic dose of FFC is reversible and safe for O. niloticus.

Summary: This study aimed to investigate the toxic effects of buprofezin insecticide on Nile tilapia. Exposure to buprofezin led to significant increases in serum transferase activity, urea and creatinine levels, as well as oxidative stress characterized by changes in MDA, GSH, SOD, and CAT levels. The upregulation of IL-1 beta and COX-2 genes in various organs indicated an inflammatory response, while histopathological alterations were observed in multiple tissues. Immunohistochemical analysis showed expression of iNOS in hepatocytes in the buprofezin-treated group, suggesting tissue damage was mediated by oxidative stress and inflammation rather than apoptosis.

Summary: This study investigates the potential genotoxic and histopathological effects of nano-TiO2 exposure on Nile tilapia. Results show that nano-TiO2 induces concentration-dependent erythrocytic DNA damage and micronuclei induction. Histopathological alterations, including hepatic parenchyma and intestinal mucosa necrosis, were observed in the fish exposed to nano-TiO2. Bulk TiO2 exposure increased liver damage and erythrocytic DNA damage, suggesting its dissolved form is also biologically active. Further research is needed to assess the environmental risks of nano-TiO2 and bulk TiO2 at realistic levels.

Summary: The study investigated the effects of levamisole hydrochloride dietary supplementation on the lipid and protein profiles of Nile tilapia through histopathological analyses and MALDI-TOF MS. Results showed improved stomach health in fish fed with 100 and 150 mg/kg levamisole, with no significant changes in liver but alterations in gill tissue. Protein and lipid profiling revealed that the 100 mg/kg levamisole supplementation provided the greatest benefits for Nile tilapia fingerlings.

Summary: In this study, the oral administration of oxytetracycline in Nile tilapia had a slight effect on feed intake and growth, with dose-dependent reduction in feed intake and dose-dependent mortalities. Oxytetracycline residue levels in fish muscle were within the acceptable range, and any pathological changes caused by oxytetracycline were mild to moderate and could be overcome by the fish over time.

Summary: An analytical method using modified QuEChERS procedure and DLLME technique was developed, optimized, and validated for the determination of erythromycin A (ERY) residues in fish fillet. The method exhibited LOD and LOQ of 0.1 μg/kg and 1 μg/kg, respectively. It demonstrated linearity in the range of 1 to 20 μg/kg, with precision (CV < 6.3%) and accuracy (recovery ranging from 103 to 110%). The method was further applied to study the residual depletion profile of ERY in fish (Piaractus mesopotamicus) after oral administration, with a withdrawal time estimated at 240 degree-days for concentrations below the maximum residue limit (MRL 100 μg/kg).

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
