Summary: This study investigated the ameliorative effects of Spirulina and Saccharomyces cerevisiae on fipronil toxicity in Nile tilapia fish. The results showed that fipronil had negative effects on growth performance, hematological and biochemical parameters, as well as genotoxicity in Nile tilapia. However, these negative effects were mitigated by dietary supplementation of Spirulina and Saccharomyces.

Summary: This study investigated the relationship between VE and PAP in fish and uncovered the function of PAP. Both VE and PAP showed antioxidant effects in the liver and serum of Nile tilapia, increasing the activities of antioxidant enzymes and improving miRNA expression profiles. VE promoted the accumulation of PAP, which entered the nucleus to inhibit the expression of XRN genes, similar to its function in plants. These findings lay the foundation for the application of PAP as a new antioxidant agent in fish farming and provide further understanding of VE's antioxidant function in fish.

Summary: This study found that exposure to different sub-lethal concentrations of profenofos caused various blood biomarker changes in Nile tilapia. Glucose and white blood cell levels increased, while hemoglobin, red blood cell, and packed cell volume decreased. The exposure also led to abnormal erythrocytic morphology and cellular abnormalities in the fish.

Summary: Trace elements such as titanium, zirconium, thorium, and uranium are present in black sand after weathering and corrosion. This study found that black sand not only contains precious metals but also rare earth elements. Lithophilic elements like lithium, uranium, and tin negatively affect the aquatic life in lakes and reservoirs. The experiments conducted on Nile tilapia exposed to isolated black sand revealed significant changes in blood biomarkers, antioxidant balance, morpho-nuclear erythrocyte's alterations, and histopathological signs. These findings suggest that black sand from Red Sea beach can impact the hematology, biochemistry, and antioxidant parameters of Oreochromis niloticus, and induce cellular and nuclear abnormalities in erythrocytes.

Summary: This study evaluated the effects of different probiotic strains on the growth and infection resistance of tilapia. The results showed that feeding tilapia with a multi-strain mixture of probiotics improved their survival rate and infection resistance. Additionally, probiotic supplementation also increased various blood parameters in the fish.

Summary: Aquaculture feed containing olive oil (OO) instead of fish oil (FO) can cause oxidative stress and impair gonad development in fish. This study investigated the effect of dietary OO-induced oxidative stress on ovarian development and found that supplementation with vitamin E (VE) could mitigate the negative effects. OO reduced growth rate, inhibited antioxidant enzymes, delayed ovarian development, decreased sex hormone levels, and affected lipid metabolism in fish. However, supplementation with VE improved antioxidant capacity, alleviated inflammation and abnormal lipid metabolism, possibly through regulating the nrf2-nf-kb signaling pathway.

Summary: The rapid expansion of tilapia aquaculture in Bangladesh has led to increased use of pharmaceuticals. This study investigated the effects of zeolite on water quality, growth performance, hematology, gut microbiota, and heavy metal content of Oreochromis niloticus. The results showed that zeolite significantly influenced growth indices and reduced heavy metal concentrations in sediment, water, and fish flesh.

Summary: Polyacrylamide microplastics produced in the environment have adverse effects on aquatic organisms, causing global concern. This study aimed to assess the toxicity of different concentrations of polyacrylamide microplastics on Oreochromis niloticus. Characterization of the microplastics was conducted using Fourier transform infrared and Raman spectroscopy, confirming their presence in the gills of the fish. The microplastics were found to significantly affect antioxidant enzymes, increase oxidative stress levels, and induce histological changes in various organs, highlighting their harmful effects on fish health.
