“…Piscine poikilocytosis is induced by foreign particles, heavy metal toxicity, pharmaceuticals, and antibiotics, leading to altered erythrocyte morphology and anemic conditions [3,5,[13][14][15][16][17]. Dietary florfenicol and emamectin benzoate cause erythro-morphological alterations in healthy Oreochromis niloticus juveniles [2,3,11,12].…”

Fish health assessment is essential for maintaining sustainable aquatic ecosystems and ensuring the well‐being of wild and farmed fish populations. Hematological parameters are crucial indicators of fish health, with poikilocytosis emerging as a fundamental marker with significant diagnostic value. Poikilocytosis refers to abnormally shaped erythrocytes in bloodstream, reflecting underlying physiological and pathological conditions. Poikilocytosis can occur in various fish species and can be influenced by environmental stressors, infectious agents, nutritional deficiencies, and exposure to pollutants. Morphological alterations in erythrocytes, such as acanthocytes, echinocytes, dacrocytes, schistocytes, spherocytes, and codocytes are common poikilocytes in fish. Understanding the relationship between poikilocytosis and fish health has important implications for disease diagnosis, monitoring, surveillance, and management. By quantifying poikilocytic changes, researchers and veterinarians can differentiate normal variations from pathological conditions, facilitating targeted interventions and treatment strategies. While most studies have focused on heavy metal toxicity, stressors, nutritional deficiencies, pollutants, and therapeutics, the etiological induction of poikilocytosis in fish health has been overlooked. Nonetheless, poikilocytosis remains a valuable biomarker for assessing fish health and their environment. This review highlights piscine poikilocytosis as a significant fish hematological biomarker and its importance in understanding their health and culture conditions.

“…The strength of these composites depends on the type of reinforcement used, which must have a high strength-to-weight ratio and a high modulus ratio in order to effectively withstand applied loads [11]. Various types of ceramic nanoparticles, such as ZnO, ZrO2, MgO, B4C, Al2O3, TiB2 and SiC, are commonly used as reinforcements due to their excellent properties, including high hardness, refractoriness, wear-resistance, and high compressive strength [12], [13], [14], [15], [16], [17]. To produce aluminium nano metal matrix composites, effective casting techniques are crucial.…”

This study investigates the impact of Yttria Stabilized Zirconia (YSZ) and T6 heat treatment on the mechanical and microstructural properties of A6082-based Metal Matrix Composites (MMCs) prepared using the conventional stir casting route. A6082 is widely used in various industrial applications due to its excellent physical, structural and functional properties with good corrosion resistance. YSZ with superior mechanical and thermal properties that can enhance the strength and wear resistance of aluminium-based composites. T6 heat treatment is a widely adopted technique to improve the material properties of aluminium alloys. The results of this study indicate that the T6 heat treatment significantly refines the grain structure of the composites, resulting in improved hardness and tensile values compared to untreated samples. Mechanical properties are also enhanced by YSZ's integration into the composites, with a 9wt.% YSZ addition to the matrix alloy leading to a noticeable improvement in hardness for both the untreated and treated composites. The tensile parameters show a similar trend, with a gain in Ultimate Tensile Strength and Yield Strength up to 6wt.% YSZ addition, after which the findings follow a downtrend (at 9wt.%). The results of this research show that A6082/YSZ composites subjected to T6 heat treatment have great promise as a high-performance material.

Antibiotics are crucial in the control of bacterial infections on fish farms. However, the influence of licensed antibiotics on DNA damage, histological changes, and protein differentiation in some farmed fish species is unidentified. The current study aimed to investigate the effect of therapeutic (80 mg/kg body weight/day) and high doses (160 mg/kg body weight/day) of oxytetracycline (OTC) on some biological indices, protein differentiation, histological changes, and DNA damage in Oreochromis niloticus (n = 360; 40 ± 3.5 g) and the potential positive effects of dietary ascorbic acid (AA) and whether it is capable of reducing the deleterious impacts of OTC and working synergistically to increase fish disease resistance and decrease morbidity and mortality rates. In the current study, fish were fed diets with or without OTC (80 or 160 mg/kg body weight/day) and AA (100 mg/kg diet/day) for 28 days, followed by a bacterial stress test with two different virulent strains for 14 days. Treatments include CTR (control; without additives), AA, OTC80, OTC160, OTC80 + AA, and OTC160 + AA. The results revealed that the AA group had the best antioxidative (significant increase in SOD, CAT, and GPx) and immunomodulatory effects (an increase in IgM, nitroblue tetrazolium, and total leucocytic count). Furthermore, the hematological parameters, immune indices (NBT), and antioxidant enzymes were significantly reduced by OTC160 (p ≤ 0.05). The results also showed that OTC160 notably augmented the activity of liver (ALT, AST, and LDH) and kidney (creatinine and urea) damage markers (p ≤ 0.05). OTC160 revealed considerable hepatic and renal tissue damage and significantly higher hepatocyte DNA damage. Pathological changes and DNA damage were directly correlated to the dosage of OTC exposure, where they were more severe in OTC160. OTC80 showed insignificant changes in most parameters. Compared to CTR, the inclusion of AA in the O. niloticus diet significantly restored the biological indices, histological changes, and DNA damage in OTC-treated groups. The morbidity and mortality percentages after bacterial challenge were significantly lower in the OTC80 + AA group, followed by the OTC160 + AA group than in the CTR. These results corroborate the use of AA as a potent antioxidant and immune stimulant and a potential co-adjuvant to OTC in the diet of O. niloticus to reach optimal resistance to disease.
