Polystyrene nanoplastic (PS-NPs) and Engine oil (EO) pose multiple ecotoxic effects with increasing threat to fish ecosystems. The current study investigated the toxicity of 15 days exposure to PS-NPs and / or EO to explore their combined synergistic effects on Nile tilapia, Oreochromis niloticus (O. niloticus). Hematobiochemical parameters, proinflammatory cytokines, and oxidative stress biomarkers as well as histological alterations were evaluated. The experimental design contained 120 acclimated Nile tilapia distributed into four groups, control, PS-NPs (5 mg/L), EO (1%) and their combination (PS-NPs + EO). After 15-days of exposure, blood and tissue samples were collected from all fish experimental groups. Results indicated that Nile tilapia exposed to PS-NPs and / or EO revealed a significant decrease in almost all the measured hematological parameters in comparison to the control, whereas WBCs and lymphocyte counts were significantly increased in the combined group only. Results clarified that the combined PS-NPs + EO group showed the maximum decrease in RBCs, Hb, MCH and MCHC, and showed the maximum significant rise in interleukin-1β (IL-1β), and interleukin-6 (IL-6) in comparison to all other exposed groups. Meanwhile, total antioxidant capacity (TAC) showed a significant (p < 0.05) decline only in the combination group, whereas reduced glutathione (GSH) showed a significant decline in all exposed groups in comparison to the control. Both malondialdehyde (MDA) and aspartate aminotransferase (AST) showed a significant elevation only in the combination group. Uric acid showed the maximum elevation in the combination group than all other groups, whereas creatinine showed significant elevation in the EO and combination group when compared to the control. Furthermore, the present experiment proved that exposure to these toxicants either individually or in combination is accompanied by pronounced histomorpholgical damage characterized by severe necrosis and hemorrhage of the vital organs of Nile tilapia, additionally extensively inflammatory conditions with leucocytes infiltration. We concluded that combination exposure to both PS-NPs and EO caused severe anemia, extreme inflammatory response, oxidative stress, and lipid peroxidation effects, thus they can synergize with each other to intensify toxicity in fish.

“…Nanochitosan not only aids in medicinal applications but also acts as a valuable supplement carrier, contributing to overall fish health. The role of CNPs as beneficial additives in fish feed, stimulating growth, boosting immune defenses, and reducing pathogenic bacterial proliferation in the gastrointestinal tract [8]. Previous research has revealed compelling evidence showcasing the bactericidal properties of chitosan nanoparticles (CNPs) against A. hydrophila bacteria [9].…”

One of the bacterial types that affects freshwater fish is Aeromonas hydrophila. These bacteria cause the occurrence of Motile Aeromonas Septicemia (MAS) disease. This study investigates the impact and optimal dosage of chitosan nanoparticles (CNPs) loaded with sidr leaves extract (SLE) on clinical manifestations, growth, hematological parameters, and survival rates of Pangasius sp. infected A. hydrophila. The experimental design employed a Completely Randomized Design with five treatments and three replications, utilizing 150 fish with an average length of 7-9 cm. Treatments included the addition of 10 ppm tetracycline (K+) in the diet and CNPs SLE with concentrations A (0 ppm), B (450 ppm), C (500 ppm), and D (550 ppm). The results demonstrate that incorporating CNPs SLE into the diet yields beneficial effects on infected Pangasius sp., leading to faster recovery from clinical symptoms, enhanced growth rates, and increased survival rates of up to 85%. The optimal dosage of CNPs SLE for Pangasius sp. infected A. hydrophila in the feed is determined to be 500 ppm.

“…This biopolymer is biodegradable and possesses many beneficial properties, such as biocompatibility, nontoxicity, and antimicrobial, hemostatic, anti-inflammatory, antioxidant, and adsorption enhancement effects [ 30 , 31 ]. Recently, in an aquaculture system, chitosan was experimentally applied, and its feed supplementation optimally improved probiotic potency under in vivo gastrointestinal conditions and consequently resulted in promising non-plant-delivered prebiotics with multiple biological activities [ 32 , 33 ] in some fish species, including brown trout ( Salmo trutta fario ) [ 34 ], hybrid grouper ( Epinephelus fuscoguttatus ♀ × E. lanceolatus ♂) [ 35 ], silver barb ( Barbonymus gonionotus ) [ 36 ], and Nile tilapia ( Oreochromis niloticus (L.)) [ 37 ]. However, its prebiotic effects on Acinetobacter KU011TH and the synbiotic effects of these components on Clarias catfish or its hybrid have never been investigated.…”

The effects of potential synbiotic chitosan and Acinetobacter KU011TH mixture on growth performance, immune response, and A. hydrophila resistance were investigated for the first time. The control group was fed a basal diet (A), and group B was given the formula B diet that was supplemented with chitosan at 20 mL/kg diet via top dressing. The other synbiotic groups, C, D, and E, were top-dressed with the target probiotics at 1 × 108, 1 × 109, and 1 × 1010 CFU/kg diet, respectively, and coated with the same concentration of chitosan. Fish were continuously fed the five different feeds for 16 weeks during winter. At the end of the trial, the growth parameters of the test groups did not significantly differ from those of the control (p > 0.05). All the symbiotic-chitosan treatments significantly increased various hematological and serum immune parameters. Moreover, the expression levels of immune-related genes were strongly elevated in the head kidney and spleen, whereas upregulated expression was observed in the liver and whole blood (p < 0.05). Survival analysis indicated that fish in groups B and C showed significantly higher survival (84.33 ± 2.21 and 79.50 ± 6.34%) than those in groups A, D and E (55.33 ± 8.82%–74.00 ± 6.50) (p < 0.05) after injection with A. hydrophila for 14 days.
