Summary: This study evaluated the effects of Spirulina and Betaine on the growth performance, hepato-renal biomarkers, immune response, and protective effect against Aeromonas infection in Nile tilapia. The results showed that the dietary inclusion of Spirulina and Betaine improved weight gain, final weight, and food conversion ratio, while also regulating levels of biomarkers and cytokines in the fish. Food supplemented with Spirulina and Betaine demonstrated significant protective power against Aeromonas infection in the Nile tilapia.

Summary: The study involved two experiments to explore the anesthetic efficiency, hematological, and biochemical effects of thymol on Nile tilapia. Thymol was found to induce anesthesia at concentrations ranging from 20 to 100 mg L-1 within 56.3-491s. Anesthesia had no significant effects on various blood parameters, but led to significant changes in plasma cortisol, glucose, lactate, and other indicators. Thymol may induce less stress and oxidative stress compared to eugenol, but further research is needed for conclusive results.

Summary: The effects of individual polypropylene microplastics (PP-MPs) and combined PP-MPs and boron on biomarkers in red tilapia were investigated in this study. Results showed that higher concentrations of individual PP-MPs decreased acetylcholinesterase (AChE) and malondialdehyde (MDA) in fish, but increased superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione (GSH) in fish liver. Mixed concentrations of boron and PP-MPs decreased AChE, GSH, and MDA activity, but increased CAT, SOD, and GPx activity in fish.

Summary: The study demonstrated that feeding African catfish males with 200 mg Ge/kg diet significantly improved growth performance, sperm quality, antioxidant capacity, and other reproductive parameters compared to other treatments. This suggests that dietary Ge at a level of 200 mg/kg has the potential to enhance reproductive success in adult African catfish males and contribute to the sustainability of aquaculture for this species.

Summary: This study evaluates the use of fresh green azolla (FGA) as a replacement for daily fish feed intake. The results show that a 20% replacement with azolla leads to the highest growth performance, hematological parameters, and feed conversion ratio. Furthermore, the activities of intestinal enzymes are highest in the 20% replacement group. Additionally, a replacement level of 20% improves antioxidant response and reduces muscular pH, stored loss, and frozen leakage rate.

Summary: Aquaculture plays a crucial role in providing high-quality aquatic food for consumption worldwide. However, the aquaculture sector in Egypt is highly vulnerable to the adverse impacts of climate change. Climate change leads to changes in water availability, decreased water quality, saltwater intrusion, and salinization of groundwater, which pose threats to freshwater aquaculture. Additionally, higher temperatures not only reduce dissolved oxygen levels but also increase disease spread and fish mortality, resulting in decreased fish production. Flooding from rising sea levels further affects aquaculture activities in lowland areas. This article provides an overview of the aquaculture sector in Egypt, explains climate change and its causes, discusses its effects on different aspects of aquaculture, and reviews mitigation strategies to minimize the negative impacts of climate change on fish farming, particularly in Egypt.

Summary: The aim of this experiment was to enhance the resistance of hybrid red tilapia to chronic cold stress by increasing unsaturated fatty acids and evaluating their effects on various aspects of fish physiology. It was found that by gradually increasing the use of Aquafat-O-(R) in the diet, the negative effects of cold stress were mitigated.

Summary: The purpose of this trial was to evaluate the effects of substituting lipid sources on the growth, feed utilization, body biochemistry, blood constraints, and fatty acid profile of Thinlip grey mullet fingerlings. Four lipid sources were compared to fish oil as a basal diet, and the substitution showed a non-significant but notable influence on growth performance. Fingerlings nourished by poultry viscera oil had significant improvements in feed utilization, while those nourished by plant oil had lower body lipid contents. The fatty acid composition of the fish flesh reflected the dietary fatty acids, with higher levels of polyunsaturated fatty acids in fish fed fish oil.

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.
