Efficacy of Amphora coffeaeformis supplemented diets in improving growth performance, health status, and resistance to Aeromonas sobria in Oreochromis niloticus exposed to suboptimal temperature conditions

Journal of Applied Phycology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 31, 2025

Abstract Climate change affects aquaculture to a significant extent, while one of the primary threats Nile tilapia ( Oreochromis niloticus ) growth and health is suboptimal temperatures. The objective this study was assess effects Amphora coffeaeformis powder extract on performance status grown in temperature (21 °C). A total 180 fish (31.39 ± 0.5 g) were randomly allocated into six groups, each with three replicates. control group fed basal diet. second third groups supplemented 50 g kg −1 (AMP50) 70 (AMP70) A. powder, respectively. fourth fifth received (AME50) (AME70) extract, sixth (OXY) diet 500 mg kg⁻ 1 oxytetracycline. After 60-day feeding trial, all challenged Aeromonas sobria . findings indicated that , particularly at concentration diet, significantly enhanced performance, hematological biochemical parameters, antioxidant immunological markers. Additionally, it notably increased resistance against These results suggest supplementation, AME effectively mitigates productivity by enhancing growth, health, disease resistance.

A Hypothetical Protein Fragment from Large Yellow Croaker (Larimichthys crocea) Demonstrates Significant Activity Against Both Bacterial and Parasite

Fishes, Journal Year: 2025, Volume and Issue: 10(3), P. 109 - 109

Published: March 4, 2025

Antimicrobial peptides (AMPs) are biocompatible and biodegradable, making them an attractive alternative to traditional antimicrobial agents chemical preservatives. Here, a novel α-helix amphiphilic anionic AMP Lc149 was screened from large yellow croaker (Larimichthys crocea) using Bacillus subtilis expression system. is hypothesized protein fragment not annotated in the genome of croaker. Both extracellular recombinant (rLc149) exhibited significant killing effects against Gram-negative Escherichia coli Vibrio harveyi. Scanning transmission electron microscopy revealed that rLc149 had ability disrupt bacterial cell membranes, causing irregular morphology, severe membrane damage, cytoplasm agglutination, intracellular content leakage. Confocal laser scanning flow cytometry further confirmed destruction mortality rates over 80%. Gel retardation assays SDS-PAGE electrophoresis showed unable bind DNA, but did reduce contents. Additionally, maintained antibacterial activity E. V. harveyi upon exposure temperatures 25–100 °C, UV radiation time 0–60 min, pH levels 3–12, different proteases. Biosafety low hemolytic toxicity erythrocytes croaker, rabbit, shrimp, cytotoxicity kidney cells HEK 293T cells. More deeply, also possessed parasites. Therefore, can be considered antiparasitic drug fisheries.

Dietary Pelargonium Sidoides extract mitigates thermal stress in Oreochromis niloticus: physiological and immunological insights

Veterinary Research Communications, Journal Year: 2025, Volume and Issue: 49(3)

Published: March 24, 2025

Abstract Extreme water temperatures caused by climate change constitute a serious threat to aquaculture producers. Aquatic ectotherms, which are unable regulate their body temperature, highly affected temperature changes and serve as excellent models for studying the effects of these factors. This study aimed examine impact extreme variation on growth, biological indices, antioxidant capacity, histology, disease resistance Oreochromis niloticus . The fish were exposed 17 °C, 25 °C (control), or 33 30 days, imitating events. Additionally, mitigation trial was conducted via dietary Pelargonium sidoides root extract (PS). Compared with that at growth performance significantly impaired thermal stress. exposure O. stress, especially cold elicited significant increases in stress biomarkers (cortisol glucose), hepatorenal functions (AST, ALT, LDH, creatinine), lipid profiles (triglyceride, cholesterol, HDL, LDL). Cold induced immunosuppression terms reduced total protein, phagocytosis, serum bacterial activity, immunoglobulin, white blood cells, all increased susceptibility Aeromonas hydrophila infection mortality. In addition severe pathological lesions gills, liver, intestine, causes an imbalance antioxidant/oxidative Nevertheless, PS counteracted detrimental impacts conclusion, may be recommended enhancing immunity antioxidative mitigate These findings useful developing hypotheses about physiology immunology extreme-temperature environments.

Assessing the impact of risk perception on fisheries performance: a structural equation modeling approach in coastal fisheries

Frontiers in Marine Science, Journal Year: 2025, Volume and Issue: 12

Published: April 22, 2025

Risk perception is crucial for making effective fisheries management strategies. However, this role of risk needs to be addressed, particularly in developing countries. Published literature documents such a scenario the case Pakistan, which results decreased economic contribution sector. Despite its importance, managing sector absent online scientific studies. The present study strives address research void by analyzing survey-based data collected through snowball sampling between May 2022 and October 2024. Multivariate analysis, viz., Structure Equation Modeling (SEM), was done Statistical Package Social Sciences (SPSS) as well Analysis Moment Structures (AMOS). Cronbach’s alpha values all constructs were above 0.6, with highest being 0.962 policies regulations risk, confirming reliability. Confirmatory Factor (CFA) indices, including Comparative Fit Index (CFI) (0.933) Tucker-Lewis index (TLI) (0.916), indicated good model fit, acceptable construct reliability (CR) Average Variance Extracted (AVE) values. SEM showed that (estimate = -0.425, p 0.000), environmental -0.251, 0.007), consumption -0.265, 0.000) negatively impacted performance, while -0.113, 0.121) infrastructure logistics -0.073, 0.411) insignificant. significant mediator varying effects across Sindh Balochistan.
