Ammonia exposure can be considered more stressful for aquatic animals when it coincides with high temperature. This study was conducted to detect the effects of ammonia and heat stress their interactions on histological features gills liver tissues expression responses immune antioxidative related genes in Nile tilapia. Thus, 180 fish were divided into four groups (triplicates), where first third kept clean water without total ammonium nitrogen (TAN) exposure. At same time, second fourth exposed 5 mg TAN/L. After seven days, temperature raised (without toxicity) (exposed TAN/L) up 32 °C under these conditions 24 h. While optimum (27.28 °C) then dissected. Marked upregulation keap1 seen ammonia/heat stress. The mRNA levels nrf2, nqo-1, cat, gpx downregulated all stressed groups, lowest recorded group. transcription ho-1 upregulated while complement C3 gene livers lysozyme nf-κB, il-1β, tnf-α higher group than highest level tnf-α, il-8, hsp70 observed co-exposure triggered degeneration primary secondary gill filaments telangiectasia vascular congestion epithelium while, showed hepatic visible necrotic changes nuclear pyknosis.

Exploring the Roles of Dietary Herbal Essential Oils in Aquaculture: A Review

Animals, Journal Year: 2022, Volume and Issue: 12(7), P. 823 - 823

Published: March 24, 2022

The aquaculture sector is one of the main activities contributing to food security for humanity around globe. However, aquatic animals are susceptible several farming stressors involved in deteriorated growth performance, reduced productivity, and eventually high mortality rates. In some countries still, antibiotics chemotherapies comprehensively applied control biotic stressors. Aside from apparent benefits, continuous usage develops bacterial resistance, deteriorates populations, accumulates these compounds environment. Alternatively, environmentally friendly additives were used avoid direct indirect impacts on ecosystem human health. aquaculture, medicinal herbs extracts extensively approved their growth-promoting, anti-inflammatory, antioxidative properties. Herbal essential oils contain many bioactive components with powerful antibacterial, antioxidative, immunostimulant potentials, suggesting application animals. Essential can be provided via diet benefit by improving well-being health status. use aquafeed has been studied a variety determine beneficial roles optimum doses. outputs illustrated that herbal exciting alternatives prominent promotion, roles. Herein, we reviewed aquaculture. This review also aims describe trends use, mainly commercial fish species, analyze different factors affect oils' efficacy immune responses finfish species.

Water physicochemical factors and oxidative stress physiology in fish, a review

Frontiers in Environmental Science, Journal Year: 2023, Volume and Issue: 11

Published: Sept. 15, 2023

Fish are among the best-studied aquatic animals due to their economic and ecological values. meat is most affordable protein source for economically weaker section of people. The environment almost all ecosystems has a specific influential role on or by fishes. Therefore, studying stress biology, especially oxidative stress, vital because it can influence growth, production, reproduction, etc. To review above topic, peer-reviewed electronic databases, including Web Science, science direct, PubMed, Google Scholar, Scopus, AGRICOLA, were searched with keywords associated fish, diseases, abiotic such as effects water dissolved oxygen, temperature, salinity, hardness, alkalinity, pH, pollutants, heavy metals, anthropogenic activities, was reviewed in current article draw conclusion updated relation that exists between fish physiology, disease, stressors. Oxidative redox regulatory levels under parameters anti-stress responses differ various models. Undoubtedly, factors modulate health status greater extent, therefore, these must be considered priority basis improve general immunity fish. statement remains valid both saline freshwater habitats.

Genome-Wide Association Study Reveals Growth-Related SNPs and Candidate Genes in Largemouth Bass (Micropterus salmoides) Adapted to Hypertonic Environments

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(5), P. 1834 - 1834

Published: Feb. 20, 2025

Sustainable development of the largemouth bass industry is hindered by limited freshwater resources. Consequently, expansion farming space brackish and saline water aquaculture has become imperative. Largemouth an economically important fish species. However, there presently a lack germplasm resources with capacity to adapt hypertonic environments maintain rapid growth. A genome-wide association study technique used for detection genetic variants associated specific phenotypic traits. In this study, we firstly applied explore potential single-nucleotide polymorphism (SNP) locus candidate genes growth adaptation environment bass. total 10 growth-related SNPs were obtained on chromosome 16, SNP16:4120214 was significant SNP peak. Based these SNPs, 23 annotated in genome, including Nkcc1, Mapkap1, Hmgcs1, Slc27a6, Shroom3. Shroom3 expression significantly higher individuals enriched most growth-advantageous genotypes. upregulation beneficial hyperosmotic environments.

Balanced aquafeed is the key factor for enhancing productivity of aquatic animals. In this context, animals require optimal amounts lipids, proteins, carbohydrates, vitamins, and minerals. The original plant animals’ ingredients in basal diets are insufficient to provide with suitable Concurrently, elements should be incorporated doses, which differ based on diets’ species, age, size, composition. Selenium one essential trace involved various metabolic, biological, physiological functions. Se acts as a precursor antioxidative enzyme synthesis leading high total capacity. Further, can enhance immune response tolerance infectious diseases. Several metabolic mechanisms, such thyroid hormone production, cytokine formation, fecundity, DNA synthesis, sufficient addition. recent progress nanotechnology industry also applied production nanoparticles. Indeed, nanoparticles elaborated more soluble bioavailable than organic non-organic forms. aquaculture, multiple investigations have role performances wellbeing review, outputs studies associated were simplified presented research development.

The performance rate markedly higher in reared 0, 8 ppt than ( p < 0.05). Before stress, superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) activities, malondialdehyde (MDA) increased 12-ppt After all groups showed marked SOD, CAT, GSH, MDA before same manner Furthermore, group severe intestinal, gill, liver histological features. glucose cortisol exposed 0 gradually either or after highest values ALT, AST, urea, creatinine, lowest total protein, albumin, globulin observed ppt.
