Summary: Co-infections with various ectoparasites and bacteria were found in a private Nile tilapia farm in Egypt, leading to high fish mortality. The application of peracetic acid effectively reduced the infection by Aeromonas hydrophila and improved the survivability of Nile tilapia by eradicating the ciliated protozoans Ichthyophthirius multifiliis and Trichodina centrostrigeata.

Summary: Streptococcus iniae is a re-emerging bacterial pathogen in freshwater and marine aquaculture worldwide. Currently, in the United States, there are no commercial vaccines available for S. iniae, and autogenous vaccines have limited protection. Serial passage of S. iniae in the presence of rifampin may generate immunogenic live-attenuated vaccines that confer protection against heterologous strains.

Summary: This study investigates the effect of different bacterial concentrations on the immunity of Nile tilapia and identifies the optimal vaccine concentration to induce immunity. The results show that a vaccine concentration of 10(6) CFU/fish is effective in inducing immunity. Additionally, it is found that high concentrations of Streptococcus agalactiae do not significantly affect the mortality of the Nile tilapia.

Summary: This study characterized two Trichodina species infecting farmed Nile tilapia using morphological, molecular, and immunological approaches, identifying Trichodina heterodentata and T. centrostrigeata. Gene expression levels of MHCII beta and CD4 genes were increased during trichodinid infection. Chemicals like potassium permanganate and hydrogen peroxide were successfully verified to control trichodiniasis in a small-scale trial.

Summary: This study evaluated the infection status of parasitic pathogens in freshwater sutchi catfish and silver dollar farmed in Alborz province, Iran. Six parasite species, including five protozoan species and one monogenean species, were identified in the examined fish. The overall prevalence of the recovered parasites was 46.43%. The identification of these new parasite hosts is important for protecting fish health.

Summary: This study compared the different tolerance mechanisms to Streptococcus agalactiae in three tilapia lines through transcriptome analysis. The results showed that numerous metabolic and immune-related pathways were activated in all three tilapia lines 48 hours after infection. Hybrid tilapia exhibited stronger resistance to Streptococcus agalactiae, which was associated with differential expression of specific genes.

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: Fish parasites, such as Neoechinorhynchus buttnerae, can accumulate high concentrations of trace metals and serve as bioindicators of environmental contamination. The presence of metals in the parasite was significantly higher than in the host fish Colossoma macropomum, indicating their ability to accumulate metals. The results suggest that the parasite directly influences the concentrations of trace metals in the fish tissues.

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.
