“…These results might be attributed to experimental infection where this result has been confirmed by histopathological lesions in the liver and kidney. These results are in harmony with the result of Fadl, Barakat, and Elgohary (), Fadl et al () and El‐Habashi et al () in Nile tilapia infected with Aeromonas hydrophila and Rastiannasab, Afsharmanesh, Rahimi, and Sharifian () in common carp with parasitic infection.…”

The present investigation aimed to evaluate the effect of dietary chitosan supplementation on growth performance, body composition, immune response and histopathology of Nile tilapia, and also the in vitro antibacterial activity of chitosan against Streptococcus agalactiae (S. agalactiae). About 180 fish (average body weight 39.3 ± 0.3 g) were randomly divided into three groups according to chitosan supplementation: control group (basal diet without chitosan), Ch3 group (3 g chitosan/ kg diet) and Ch5 group (5 g chitosan/kg diet). Growth performance parameters and body proximate composition were measured before infection but biochemical parameters and lysozyme and antibacterial activities before and after experimental infection. Results of the present investigation showed dietary chitosan (5 g chitosan/ kg diet) significantly (p < .05) improved growth performance parameters, body composition (dry matter, crude protein, ether extract, ash, and carbohydrate) and serum biochemistry (total protein, albumin, globulin, with no effect on AST, ALT, urea and creatinine) before infection in Ch5 group than the control. After infection, liver enzymes (serum AST and ALT) were maintained lower in fish fed Ch3 or Ch5 than the control. Serum lysozyme and bactericidal activities significantly increased (p < .05) in chitosan groups before and after the challenge. The mortality rate was markedly reduced in the Ch3 group and prohibited in the Ch5 group after the experimental infection. In conclusion, feeding 3 or 5 g chitosan/kg diet increased the growth rate and improved FCR of Nile tilapia. In addition, it reduced mortality by its antibacterial and immunostimulant effects.

“…It catalyzes the transfer of an amino group from L-alanine to  -Ketoglutarate, the products of this reversible transamination reaction being pyriuvate and Lglutamate. Elevated levels of ALT often suggest the existence of other medical problems such as viral hepatitis, diabetes, liver damage, bile duct problems, congestive heart failure, infectious mononucleosis or myopathy [22], and the results of this work with elevated level of ALT in the fish infected with the pathogens suggests that there is organ damage in the infected fish.…”

Clarias gariepinus were infected with Aeromonas hydrophila and Pseudomonas aeruginosa, and blood samples were collected weekly for biochemical analysis to analyse their enzyme activities and pathogenesis for four weeks. The enzymes includes: aspartate aminotransferase (AST), alkaline phosphastase (ALP), acid phosphastase (ACP) and lactate – dehydrogenase (LDH). The fish were distributed in three different groups in triplicates as: control (C1 C2 C3), A. hydrophila (A1, A2, A3) and P. aeruginosa (P1, P2, P3). After two weeks of acclimatization, A1 – A3 were injected with 1.5 ml of 106 cfu/ml of A. hydrophila, P1-P3 were injected with 1.5 ml of 106 cfu/ml of P. aeruginosa, while C1-C3 were pathogen free. At the end of the experiment, it was observed that there was a constant increase, in the enzyme activities of the infected fish, indicating increase in virulence with respect to weeks of exposure but P. aeruginosa had higher pathogenicity compared to A. hydrophila.

Cymothoid isopods cause serious infestations in fish that may adversely affect the aquaculture. Current study targeted investigating the enormous infestation of European sea bass Dicentrarchus labrax with cymothoid isopod, Nerocila species in a marine fish farm at Kafr El Sheikh Governorate, Egypt; accompanied with trials for treatment with malathion 57% at 0.15 and 0.30 mg/L concentrations and evaluation of the immune and antioxidants responses. For this purpose, 450 D. labrax were randomly collected alive during April 2020 and thoroughly examined for detection of external parasites. Malathion 57% treatment trial was carried out. Blood and tissue samples were collected from infested fish at zero-day (before malathion treatment) and at 24hrs, 48hrs, 3rd day, 4th day and 5th day (after malathion treatment). Isopods collected from infested fish were identified as N. orbigny and fish's external body surface and gills were the predilection sites. Both malathion concentrations were effective in eradicating N. orbigny and decreasing the isopod prevalence from 100 to 0% at the 5 th day sampling point. Infested fish revealed improved hematological parameters (Erythrocyte counts, hemoglobin, and hematocrit readings), however leucocyte and differential cells counts showed significant decrease in infested fish. Immunological parameters (Lysozyme and IgM activities) decreased, but nitric oxide increased by time after malathion application. Nerocila is considered serious parasite in aquaculture that negatively affects fish's immune and
