“…The negative impact of suboptimal and cold temperatures on tilapia health has been shown in previous studies [ 4 – 6 , 47 ]. The objective of the current study was to determine how C. sativum affected O. niloticus reared at suboptimal temperatures in terms of growth, health condition, survival rate, and resistance to A. veronii .…”

“…Exposure to suboptimal temperatures leads to the production of reactive oxygen species (ROS). Excessive ROS generation impairs physiological processes, damages DNA, induces cellular apoptosis, and suppresses the immune system [ 7 , 37 , 47 ]. In the current study, TAC, SOD, and catalase activity significantly decreased in the OT group compared to the CONT group.…”

This study (60 days) was conducted to investigate the ability of diet enriched with Coriandrum sativum powder or its extract to protect Oreochromis niloticus health and survivability at suboptimal temperature (21 ℃). One hundred and twenty (33.14 ± 0.5 g) were divided into four groups; each group has three replicates.. The first control group fed on a basal diet. Second and third groups fed on diet enriched with 30 mg/kg coriander seed powder (CP) and coriander seed ethanolic extract (CE), respectively. The fourth group (OT) fed on diet enriched with 500 mg oxytetracycline/kg diet. The results revealed that CE exhibited a considerable improvement in hematological parameters, hepatic-renal functions, antioxidant status, and immunological markers as well as remarkably increased resistance against Aeromonas veronii. It could be concluded that feeding tilapia CE enriched diet at 30 mg/kg is a recommended strategy to enhance tilapia health and resistance to A. veronii infection reared at 21 ℃.

“…Its sensitivity to low-temperature environments often leads to slow growth and even mass death. Low temperature can affect tilapia’s metabolism, immune function, cell cycle and other life activities ( Dellagostin et al, 2022 ; Velmurugan, Chan & Weng, 2019 ; Yilmaz et al, 2021 ). When the temperature is below 15 °C, the body of tilapia will be damaged, and the semi-lethal low temperature is about 10 °C ( Cnaani, Gall & Hulata, 2000 ; Li et al, 2002 ; Tave, 1990 ).…”

As an important farmed fish, tilapia has poor tolerance to low-temperatures. At the same time, different tilapia strains have apparent differences in low-temperature tolerance. In this study, using the iTRAQ method, the phosphorylated proteomics of two tilapia strains (Oreochromis niloticus and Oreochromis aureus) with different tolerances to low-temperature stress were quantitatively and comparatively analyzed, to clarify the physiological mechanism of tilapia’s response to low-temperature stress. Through the GO and IPR analyses of differentially phosphorylated proteins, a number of similarities in physiological activities and regulatory effects were found between the two tilapias in response to low-temperature stress. Many differentially phosphorylated proteins are mainly involved in lipid metabolism, cell proliferation and apoptosis. However, the difference in endurance of low temperature of these two tilapias might be related to the differences in categories, expression and modification level of genetic products which were involved in the aforementioned physiological processes. And meanwhile, the enrichment results of KEGG showed the changes of multiple immune-related and growth-related phosphorylated proteins in the cytokine-cytokine receptor interaction pathway in O. aureus are more prominent. Furthermore, the significantly enriched pathway of carbohydrate digestion and absorption in O. niloticus may indicate that low-temperature stress exerts a more severe impact on energy metabolism. The relative results would help elucidating the molecular mechanism by which tilapia responds to low-temperature stress, and developing culture of tilapia species.

“…Hypothermia exposure suppresses the innate immune system of fish, thereby increasing susceptibility to infection [ 19 ]. Furthermore, many studies have demonstrated that fish tissues have inflammatory reactions as a result of hypothermia [ 20 ]. Under hypothermia exposure, inflammatory reactions in tilapia seem tissue specific.…”

Hypothermia-exposure-induced oxidative stress dysregulates cell fate and perturbs cellular homeostasis and function, thereby disturbing fish health. To evaluate the impact of hypothermia on the freshwater drum (Aplodinotus grunniens), an 8-day experiment was conducted at 25 °C (control group, Con), 18 °C (LT18), and 10 °C (LT10) for 0 h, 8 h, 1 d, 2 d, and 8 d. Antioxidant and non-specific immune parameters reveal hypothermia induced oxidative stress and immunosuppression. Liver ultrastructure alterations indicate hypothermia induced mitochondrial enlargement, nucleoli aggregation, and lipid droplet accumulation under hypothermia exposure. With the analysis of the transcriptome, differentially expressed genes (DEGs) induced by hypothermia were mainly involved in metabolism, immunity and inflammation, programmed cell death, and disease. Furthermore, the inflammatory response and apoptosis were evoked by hypothermia exposure in different immune organs. Interactively, apoptosis and inflammation in immune organs were correlated with antioxidation and immunity suppression induced by hypothermia exposure. In conclusion, these results suggest hypothermia-induced inflammation and apoptosis, which might be the adaptive mechanism of antioxidation and immunity in the freshwater drum. These findings contribute to helping us better understand how freshwater drum adjust to hypothermia stress.
